Mechanical time timers with autonomous power. Technical specifications of the mechanical timer-outlet

As follows from the name of this device, it unites in one device an outlet and a timer. Most often, the device is inserted into a stationary outlet or an outlet of an extension cord, the power of which is continuously supplied. FROM the opposite side  in the case of the device there is (output) power outlet  for connecting the load - household electrical appliances.

Electricity at the output contacts is not constantly supplied. The time schedule for supplying voltage to the load is set by means of a built-in timer that controls the relays connecting the input and output contacts.

Such devices are available for use in a variety of conditions - in a conventional room, and for rooms with high humidity, and in a splash-proof design.

Characteristics. Regulations

A socket with a timer has the following main characteristics:

• Maximum programming time (the program can be set for a day, a week or even even longer) or a range of time intervals for interval timers;
• Accuracy of the clock and maximum temporal error in the operation of commutation of input and output circuits (relay operating time);
• The discrete setting of the switching time (it can be from a few seconds to 30 minutes);
• Load capacity of the device (maximum switched currents);
• Maximum number of possible commutations per day.

Normative international documents that are used in the design and manufacture of the instruments under consideration are the standards of the International Electrotechnical Commission IEC 60669-2-3-97, IEC 60947-6-2-92.

The load capacity of modern outlets (including those with control devices) in most cases is 16 A for alternating current  230 V with a frequency of 50 Hz.

Virtually all outlets with a timer are equipped with a built-in battery, designed for autonomous operation of the device's watches for 100 or more hours. To charge this battery, it is recommended to connect the device to the mains without load for 12 to 14 hours.

Many devices are equipped with switches that specify one of three modes - automatic (timer control of the relay), and also on or off.

Functions

Use the device in question can be used to solve a variety of tasks.

First of all, the device provides energy saving. He can turn off the heating devices while there is no one in the house, and turn them on before your arrival from work in a time sufficient to create a comfortable temperature. Enable or disable heating appliances  in the automatic mode it is not recommended by all manufacturers of outlets with a timer. Carefully read the instructions for the specific device.

By schedule, you can automatically turn on and off the outdoor lighting. Another task that can be easily solved with our device is the periodic automatic activation of the irrigation system in the garden area.

  The work of instruments (compressors, lighting devices, filters) on a strict schedule is necessary to create the necessary conditions in aquariums and terrariums. Timers are also widely used to control the operation of pool equipment.

Use controllable sockets  to create the effect of the presence of people in an empty house, which can to some extent protect from intruders. In this case, it is recommended to use instruments with a time schedule that is not set rigidly, with some random deviations.

Sockets with a trip timer (interval timers, countdown timers) are also used. In fact, this device is well known to all washing machines  and electric stoves. Turn the timer knob to set the time after which the time relay switches off the load.

Types of timers

The considered devices are classified by the type of timer.

The simplest version is an interval timer with a purely mechanical method of setting the tripping time and a mechanical clock that starts when cocked.

Socket with electromechanical timer

The most common rosette with a mechanical daily timer should be noted for a small inaccuracy - for such devices, the clock still fed from electricity. Therefore, it is more correct to say "with an electromechanical timer". For backup power in such devices, batteries are usually provided. Mechanically, with the help of, as a rule, 15-minute segments-petals, a program of switching on and off the load is set.

A socket with electronic control usually has a weekly programming interval and a liquid crystal display (indicator) for displaying the current time and parameters of the installed programs. The control of the electronic device program is carried out by means of function buttons (usually their number is from 6 to 10).

Socket with electronic control

Mechanical (electromechanical) socket - timer

Programming mechanical outlet  is performed using a rotating time disk. First of all, the current time is set against the mark on the timer body. Then, as shown in the figure, the segments (lobes) around the disk are pressed downward. The pressed segment corresponds to the time period (15, 30 minutes, depending on the model) during which the input voltage is applied to the outlet contacts of the outlet.

With this device, you can turn the load on and off at least every 15 minutes, and without limiting the number of switches during the day. It is more correct to say that the number of switches is limited by the discretion of the time setting. However, complicated, and even more so, casual programs can not be set with such a timer.

Devices of this type can be not only daily, but also weekly

Electronic outlet - timer

It should be noted that for a socket with an electronic timer, the programming process can be quite complicated. Before use, always carefully read the instructions for the specific device. The devices of different manufacturers identical in purpose can differ substantially in the way they are programmed.

Pay attention to the permissible number of shifts during the day. For different electronic devices it is different and explicitly spelled out in the passport of the device.

Sockets with electronic control allow you to set up to 140 load switching programs. Many of these devices have a "presence" program that can turn on the light in the house randomly at a specified time interval (for example, from 6am to 12am).

The discreteness of the time setting during electronic control is usually one minute (we recall that for electromechanics this figure is not less than 15 minutes).

Buying a socket with a timer - the task is not particularly difficult. Now you can buy such a device in almost any hardware store with a department of electrical goods. However, if you feel the need to get advice on using, connecting or setting up the device, it's best to contact a specialized electronics store. Obtaining documents confirming the conformity of the product to standards is also easier in a specialized firm or store.

Note that the price of a socket with an electronic timer is usually much higher than with a mechanical timer. The purchase of the first option is justified only when it really is necessary to automatically perform a weekly program and use more complex inclusion algorithms (for example, switching on light at a random moment to scare off thieves).

When performing the same schedule every day, it is advisable to stop at a socket with a daily electromechanical clock.

Timers are developed and produced electronic and electromechanical, timers are operated from the electrical network. The household timer is designed to turn on and off electrical appliances at the set time. In most cases, you can do without it, but to simplify everyday tasks with a timer you can significantly ease yourself the task and a repetitive monophonic work can easily be assigned to an electronic device called a programmable household timer.

The device performs the following main functions:

• Control of switching on and off by electrical devices. Using a household timer to control, for example, an electric heater. The household timer will save energy consumption, include heating in the apartment before arrival, provide comfortable conditions. At the same time, electricity will not be consumed until there is no home.
• Timer - controls the light. Lighting control With the help of a timer it is possible to set when it is necessary to turn on the lighting in the courtyard, for example, with the onset of twilight from 19 o'clock and from 23 o'clock you can turn off the lights and turn on in the morning.
• The household timer will feed. Breakfast is scheduled. If you put the necessary ingredients into the steamer in the evening and adjust the timer, breakfast will be ready on time. Similarly, it is convenient to operate a kettle or coffee machine.
• The timer - will wake. In the role of an alarm clock Are you tired of waking up under a sharp alarm clock? The timer can switch on any device, for example, a music center or a lamp.
• Control of household appliances according to a set schedule Many necessary electrical appliances - air ionizers, Chizhevsky chandelier - must be switched on periodically and for a certain period of time. A household timer will help you.
• Timer - take care. To help owners of aquariums Inhabitants of aquariums and terrariums need to turn on the light and air the compressor strictly at a certain time. Set the program to the timer and it will not fail.
• The timer will scare you away. Imitation of finding people in the room, apartment (for the period of vacation, went to the country ...). Mechanical and electronic timers with the function of random inclusion will make it possible to effect the presence in the house - the periodic switching on and off of light, turning on and off the sound file of the pet (for example, for the holiday period).
• Work at night. Recently, it has become important to take into account various tariffs for electricity and water supply, depending on the time of day. In this case, electrical appliances, such as a washing machine or a dishwasher, should be used at night. With this task, the timer can do without much effort.

At present, a household timer becomes an essential appliance in everyday life.Timers mechanical and digital can be used for internal device  control, time-controlled shutdown, for example, TV, lighting, heating system, cooling system, as well as terrarium systems, air humidifiers, aquarium compressors, fans, dosing and CO2 systems, mechanical gearshifts for automatic operation, etc.

Electromechanical timers differ from each other in the presence of a regulator,  allow you to operate the electrical device included in it directly, bypassing the settings of the household timer, this is convenient when you need to turn on, for example, the compressor in the aquarium and not switching the device supply voltage.

Disadvantages of household mechanical timers:

• when the voltage is lost, the program is stalled for a time that was not in the mains voltage;
• the installed program is the same for each day;
• some models tick like a mechanical alarm clock.
• more often out of order, stop rotating (the gear mechanism seems to wear out)
• ladies with chic manicure and beautiful long nails, after a power failure in the network troublesome to screw the disc in the desired position without touching the plate-levers that strive to catch the nail and knock down the entire previously exposed program.

Advantages of household mechanical timers:

• easy operation with mechanical timers.

Electronic timers, differ from each other mainly in the design of the external form and a couple of functions. Some have the function of transition to summer-winter time, other function of the response to movement (turn on when approaching the device included in the timer)

All electronic timers are equipped with a switch that allows the work of the electric device included in it to go straight through the timer settings. Electronic timers have their own accumulators, which do not allow to get lost to the tuned program when the power is cut off in the network. As soon as the power reappears, the timer runs according to the specified program.

  The difference between an electronic timer and a mechanical one:

• fast transition from summer to winter time;
• presence of the built in power supply (the program does not get off in case of power failure);
• installation of the program for each day of the week;
• the ability to install your program for each week, etc.

Disadvantages of household electronic timers:

• internal batteries are not permanent, and sometime the time will come for their full development. If you can not buy new ones and replace them, the timer can be discarded.
• as mentioned above, when the power is turned off, we can not use the prompt, as in the case of a mechanical timer and find out whether the power was off. After all, the timer does not go astray, and does not fall behind for that period of time, until there was food.

Advantages of household electronic timers:

• the program can be set for each day of its own. For example, during working days, the devices will be switched on and off according to our employment schedule at work (study), and on weekends at other times. Or in general every day at different times.
• the program can be exhibited for several days. For example, only the first or second half of the week.
• the program can be exhibited every other day.
• the program can be exhibited only for one any day.
• in relation to the mechanical timer, there are not any plate-levers, there is no gear mechanism and there is no ticking resembling an alarm clock

Timers or time relays are devices that automatically control the turning on and off of light, electrical appliances and equipment designed to support life in, audio-video equipment, heating appliances and much more.

Types of light on and off timers

All timers are divided into mechanical and electronic (digital). Mechanical are pretty primitive and will suit you if the on / off accuracy can fluctuate within 10-20 minutes. But if you need a clear program for each day with high accuracy, then you need an electronic timer.

How does the automatic light timer work?

In order to connect the time timer, you do not need to be a highly qualified specialist. All you need is just to plug in the appliance and ask him the schedule.

This device will be a great help to you. For example, a timer for light will help create the effect of the presence of hosts in the house, including turning off the light at a given time. So you do not need to worry about uninvited guests while on a long trip.

Also, the light off timer can be used if you or your family members have a habit of often leaving light in the hallway or other rooms in the house turned on, permanently leaving their homes. To save your spending on electricity, use this simple device. It is an energy-saving switch that turns off the light after 5 minutes after turning on. It is extremely convenient for use in rooms where you pass with occupied hands (staircase, hallway, staircase), a good timer in both the garage and the basement. After you leave, the light will turn off automatically.

The light-on timer is useful for you if you go home in the dark and want to see a bright light in the courtyard or on the landing, but you do not want it to burn all day long. Managing the timer is very simple - set the right time, and it will turn on the lighting for you at the given moment.

Light switches with a timer are another option for controlling the light in the house. It is a button with an indicator, for example, in the form of an hourglass, which shows how much time is left until the moment when the light turns off. This circuit breaker  great for summer residents, who would certainly be upset when they saw the light on after a month's absence.

The presence of a timer in the outlet allows you to turn it on and off at a certain time. This innovation can significantly reduce the cost of electricity and makes it convenient to operate electrical appliances. About how to choose a socket with a timer and its characteristics, let's talk further.

  Functional features of using a socket with a timer

Sockets with a timer are an automated device on which there is a timer for turning it on and off. Thus, the timer happens both electronic, and mechanical type. With the help of this type of outlet, it is possible to automate various kinds of equipment. In addition, the operation of different devices is simplified.

For example, through this outlet you can connect one of the lighting devices or a pump in the aquarium. Adjusting its inclusion and shutdown at a certain time, it will be possible without intervening to ensure the periodic operation of the pumping equipment.

With the help of such outlets it is possible to regulate the operation of the alarm system, lighting devices or watering the garden. The use of mechanical type timers allows switching the devices on and off every fifteen or thirty minutes (in relation to the selected model).

But the electronic version of the socket timer provides adjustment of the device's operation for more than seven days. In addition, the adjustment interval can be adjusted up to minutes. The built-in battery allows the timer to work even if there is no power supply.

Installing the outlet from the timers and connecting the convector to it, you can adjust its inclusion only during the stay in the people's house. In addition, by means of a socket of the timer it is possible to disconnect the socket for the night and bring it into service during the daytime. In the evening, with the help of a timer outlet, the lighting that is on the street will turn on automatically.

The function of an arbitrary inclusion on the electronic timer will allow to turn on the light in the house, even at a time when there is nobody in it. This action will help frighten thieves if they suddenly want to get into the house.

Thus, a socket with a timer is a very useful thing, with which it is possible to regulate the switching on and off of various electrical appliances, down to coffee makers and wi-fi routers.

1. The first step is to determine the function of the outlet and determine its type. Mechanical timer socket - allows you to ensure its performance within a short time interval, no more than half an hour. Such outlets are very limited. In addition, they work only with periodic human intervention. The electronic timer socket has a wide range of functionality. This version of the outlet is able to regulate the switching on and off of electrical equipment every minute. In addition, these outlets often have additional functions - simulating the presence in the house, weekly or daily inclusion, etc.

2. In addition, buy the outlet should be in the specialized electronics stores. This is how you have the opportunity to get the proper advice on how to operate, and on setting up the outlet. When choosing a socket, ask for documents confirming its compliance with the product quality standards.

3. A socket with a weekly timer is suitable for those people who need to permanently turn it off and on. For example, the adjustment of the illumination in the aquarium will be carried out for seven days, from the time of setting the outlet. These outlets provide the inclusion of devices for a whole week, while in the settings you can choose the time of operation of the outlet during each day. These programs are repeated throughout the entire life of the outlet, if necessary, they can be adjusted. The timers for weekly outlets allow the socket to be turned on in five different modes.

4. A socket with a timer is capable of turning the pump on and off in the aquarium. It is able to operate in a specified interval, for example, every hour to turn on and off. Weekly same types of outlets timers can be turned on and off no more than five times a day. The program will run daily and does not need a permanent restart.

  How to set the timer socket

On most outlets with a timer there are buttons like TIMER, WEEK, DAY, ON, OFF, AUTO. CLOCK, MINUTE, HOUR. With their help, the timer is adjusted to a certain mode of operation.

Socket with timer user manual and configuration:

1. This version of the instruction is relevant for most models of outlets with a timer, but not for everyone. Therefore, before starting work, read the instructions provided by the manufacturer.

2. To start, press the power button, after the icon appears on its display, you must press the power button and timer settings.

4. The button for pressing the timer closes the process of setting the outlet. In order to view the preset settings, you must hold the timer button for five seconds.

5. Button clocks, if available, makes the settings relevant. We recommend that you record the time of turning the timer on and off on a sheet of paper before starting to work, especially if you set up the outlet for a five-day operation.

If you have a socket-type timer of a mechanical type, then the process of setting up is much faster. In order to program the socket, the interval of its operation is followed by a special display, which rotates in a circle. Segments that are separated by 15 or 30 minutes indicate the period of operation of the outlet. Note that you should not forget about the inclusion of the device itself, so the socket with the timer will function in the previously set mode.

In addition, distinguish between sockets with the presence of a sleep timer. In this case, the inclusion of the device is not regulated. To configure these outlets, a special ring stretches on which there is a special indicator. Operating mode electrical appliance  determines the color position of the indicator. Green means disconnection of the device, yellow - its operability, and red - the occurrence of a short circuit or malfunction with the mains. To establish the exact working time of the outlet, they have a scale on which this fact is indicated.

The outlet model with the "Expert" timer has two operating modes, for switching which is used as a button, and the side part. The first mode ensures the permanent operability of the outlet, and the second one - periodic. The timer and battery ensure that the settings are saved for more than four days without electricity.

On the electronic power-on timers of the outlet, it is possible to adjust their operation in more than 150 variations. In addition, they are equipped with a function of presence, which is an additional security element of the dwelling, during the absence of the owners in it.

  Advantages and peculiarities of using weekly and daily outlets with a timer

Sockets with the presence of an electromechanical power-on timer allow you to connect both industrial and household appliances. On street sockets there is plastic protection against moisture, frost, precipitation and other external factors. On the sockets that are used in the house there are dampers, which, if necessary, block access to the socket. Daily outlets allow you to manage their work throughout the day. They have certain petals, allowing the outlet to work in a certain interval.

The principle of operation of the outlet from the timers consists in the periodic switching on and off of the device, which is regulated by means of a built-in timer. The instructions to each outlet indicate:

• general rules and wiring diagrams;
• timer adjustment;
• principle of connecting electrical appliances.

Note that if the appliance is not plugged in, it is in the inoperative mode.

If the turn-on and off times of electrical appliances are different every day, we recommend using a weekly version of outlets with a timer. They allow you to regulate electricity, even with a long absence of the owners of the house.

On electronic outlets with a timer there are liquid crystal displays, batteries, euromolders and sockets, as well as buttons for adjusting the device. The cost of such a device is much higher than the mechanical one. However, their purchase is justified only in the case of a weekly adjustment of the operation of the devices. Otherwise, you can get by and mechanical type  timer.

At the outlet with an electric timer, there are such advantages:

• the possibility of adjusting the operating time by minutes;
• selection of the day of the week during which the outlets will be switched off and on;
• the possibility of both manual and automatic inclusion;
• the timer does not depend on the power supply, the presence of the battery allows the timer to save the settings for more than four days;
• presence of the function of imitation of the presence of the owners in the house;
• the existence of an autonomous program for more than two years.

  Overview of socket manufacturers with a timer

We offer you to get acquainted with the main manufacturers of outlets with a timer and their features.

A socket with a Feron timer is distinguished by the presence of an electromechanical timer type. These rosettes are distinguished first of all by affordable cost and optimum quality. This explains their popularity. The type of timer installed in one or another outlet model determines the time interval for the operation of electrical appliances. These outlets can be either daily or weekly.

In addition, the company produces models of sockets for baths or rooms with high humidity, on the case of such a socket there is a protective casing that prevents splashes from getting.

Among the features of the weekly outlets Feron distinguish:

• control of the operation of electrical appliances in relation to the day of the week;
• the features of the outlets enable heater  at home or at the dacha, two or three hours before your arrival;
• periodic inclusion of light in the terrarium;
• imitation of the presence of people in the house, etc.

Using the use of daily outlets for the home, it is possible to perform such actions:

• the inclusion of heaters;
• switching on of lighting devices;
• turning off electrical appliances in the form of an iron, thus, it is possible to secure the home from the occurrence of a fire.

For the operability and continued operation of outlets with a Feron timer, perform a series of actions:

• take care of installing the necessary program and launching it;
• connect the outlet to the mains;
• connect the outlet to the monitored device;
• plug in the appliance;
• check the operability of the device and the execution of their specified program.

Pretty affordable price  and excellent performance characteristics are different models of sockets with a timer Feron outlet timer tm22 and Feron tm 23.

We offer you to familiarize yourself with the technical characteristics of the first model - tm22. This outlet allows you to connect to it both household and industrial appliances, such as an iron, a heater, an electric kettle, a heater, a lamp, a searchlight, an electric stove. In order to ensure the safety of small children or pets, the socket has special flaps that cover the possibility of access to it when the appliance is switched off.

The outlet is characterized by:

• eight operating modes;
• possibility of switching on or automatic shutdown;

• twelve or twenty-four hours of operation;
• possibility to work in summer and winter time;
• accidental activation of the device;

Among the features of the model outlet with the timer Feron TM23 note:

• presence of a waterproof coating;
• presence of eight operating modes;
• good performance;
• affordable cost;
• the possibility of application in the bathroom or on the street;
• ease of adjustment;
• warranty from the manufacturer.

Note that when the appliance is switched on, its plug must be firmly connected to the outlet. To clean the dust outlet, use a dry cloth.

Socket Video Timer:

In the conditions of the energy crisis, the concept of a smart house, according to which all processes are controlled by electronics, is very relevant. With the help of devices working on the principle of time relays, it's easy to integrate its individual elements. How does the socket with the timer work and what types of products is represented by the modern market, we will consider in the article.

Automation of a single function or the whole process involves the use of sensors that respond to and transmit information about the parameters of operation to the central control mechanism. But the purchase of this expensive equipment can not afford many.

Partially solve the issue of automation and power management helps install off-grid sockets.

A socket with a timer according to the principle of functioning is in many respects similar to a time relay: after the programmed time interval has expired, it closes /

The method of switching electrical contacts in such devices is based on the fact that when the relay is activated, the conductors are closed.

Depending on the type of the chosen model and its technical parameters, the smart socket is capable of configuring two types of programs:

1. Daily - when the process is limited to a time interval of 24 hours.
2. Weekly - provides the ability to program the start and finish of electrical appliances separately for each day of the week.

In any house there is a lot of equipment that can require deferred switching with the use of a timer for 220 V. Timer outlets help to solve several problems simultaneously, i.e. realize:

• Electrical equipment management.  Including washing machine, a pump, a boiler, a multivark ... Automatically turning on the sockets can also be used to turn on the light and heat the aquarium, chicken coop or shed with animals.
• Lighting control. Automatic inclusion of music and light will help to form an impression and effect of the presence of home owners in the room, so that it will protect the dwelling from the intrusion of uninvited "guests".
• Automation of agricultural works. All processes that do not require direct human participation can be successfully automated, for example, ventilation of greenhouses, care of pets, watering of plants.

The use of smart outlets when installing a two-tariff electricity meter allows the article of monthly payments to be reduced by 30-40%. During the peak hours at the rates of the hours at which the price for a kilowatt of consumed energy is 1.5 times higher than the usual one, the consumer will simply be disconnected, while at the same time consuming electricity during the hours of the lowest-priced billing.

The socket-timer will help on personal plots automatically launch a security device, illuminate the greenhouse and illuminate the territory at night

Devices of this type are very relevant for lovers of late watching TV, which often fall asleep in front of the screen. After all, in addition to the fact that the switched-on TV will continuously consume electricity for several hours, it will also act as a generator of electromagnetic waves, which negatively affect the quality of sleep.

Classification of outlets-timers

In fact, turning off the sockets can not be regarded as such in the usual sense. Unlike fixed fixed blocks or overhead points, they are more like a block adapter. The device combines in itself and an outlet and a timer.

In the case of such a switch is provided an output power jack for the possibility of connecting the plug of the appliance, as well as the plug connector, which is necessary for feeding from a stationary point. On the body of the instruments there are two pins, similar to those in electrical plug. Power supply to the output contacts in such devices is not always supplied.

Programmable switching points, working on the principle of relays, are designed to provide connection of both home appliances and professional equipment in 220 V

The main criterion for classifying devices is the range of regulation and the type of wire used. Depending on the method of setting the interval, the switched out sockets are divided into two types: mechanical and digital. Each type has its own significant advantages and inherent disadvantages.

Traditional mechanical devices

The models, produced half a century ago, worked due to the movement of the mechanism consisting of gears. They were driven by a spiral spring. The mechanical clock works on the same principle.

The models of the modern model are equipped with a pulsed slow-speed electric motor.

Thanks to a pulsed slow-speed electric motor, the current models are less noisy, but more dependent on an external power source

At the heart of the work of the devices is a traditional mechanical scheme for organizing control and monitoring the operation of the electrical point. It provides uninterrupted rotational motion of the disk, under the action of which the contacts are closed and opened.

Entering the program data of the equipment operation is set by means of separate key segments installed on the case of the timeline. Each of the keys is responsible for entrusting it to it in 15 or 30 minutes. For a day, the timer can be turned on at least every quarter of an hour. The number of cycles is limited by the discretion of the time, on average over the day it can reach 96 times.

The task of the timer is to organize the supply of electricity to the device when one of the segments is pressed. On sale there are samples in which to disconnect the device, the push buttons must be "heated", and there are those where the keys need to be lifted.

Most models of a mechanical sample are equipped with a circular timeline, the outer contour of which is a number of switching buttons

With the help of the position switch of the device it is possible to transfer from the programmable mode to the usual one. Usually it is installed from the side and equipped with a light indication device.

The principle of control of the outlet-timers of the mechanical category determined their key drawback. They can not be programmed for more than 24 hours. This is due to the fact that the speed of rotation of a disc equipped with a contact directly depends on the gear ratio of the reducer, which reduces the number of revolutions of the impulse motor shaft in one minute.

Theoretically, there are ways to make the executive disk perform a turnover not in 24 hours but in 48 hours. For example: to do this, increase the number of gears, thereby complicating the reducer, or increase the diameter of the disk itself. But such modernization is reflected in the cumbersomeness of the device, and therefore practically not used in practice.

Another significant disadvantage of mechanical outlets equipped with a timer is the dependence of their actuating disk on the normal operation of an external power source.

If the frequency of the alternating current for any reason is different from the nominal value of 50 Hz, then the mechanism starts to "run ahead" or, on the contrary, "lag"

Although the dependence of the mechanical device on the mains voltage can be considered as a plus. Even with an emergency power failure, the mechanism will still execute the specified program, only realizes the task a little later.

Electronic digital models

Electronic models have a wider range of programming. The number of variations can reach more than a hundred.

Electronic devices operate at the expense of relay circuits, which are controlled by the built-in programmable microcontroller

Programming of the device is carried out by pressing the keys on the block, the number of which can be from six to ten. Control over the state of the device and its mode of operation is carried out through the display.

The executive motor in electronic models is not dependent on an external power source because it is equipped with a battery that serves as a backup analog. The battery is able to provide autonomous operation of the device for 100 or more hours.

In the future, in order to recharge such a battery, it is only necessary to connect the device to the mains without load for 12-14 hours.

In the situation of emergency power outage due to the inclusion of the battery, the switch does not notice the difference, in any case closing the contact in the specified period

Unlike mechanical samples, in which the switching interval is limited to 15 and 30 minutes, in electronic devices it is possible to program the inclusion with an accuracy of two seconds.

The main functions of the soft keys are:

• «Timer»  - for entering and confirming data for 12 and 24-hour operation of the device;
• Hour, minute  - time setting in conjunction with the "Timer" key;
• «Week»  - selection and setting for the week;
• «Rst / Rcl»  - performs cancellation and restoration of the program;
• "On / auto / off"  - choice of manual or automatic mode of operation.

Most models have a "Random" function. The function with a floating timer ahead allows you to switch on the socket load from two minutes to half an hour in random order, thereby simulating the presence of a person in the room.

The inclusion of electrical appliances connected through the device is not tied to a specific time, which can confuse "observers" who are trying to find out if there are people in the house.

On the market there are also models that support installation, as well as remembering the shutdown / on-off modes for individual days of the week. For example, the TM-22 model of Feron.

Eligibility Criteria

Practically in all products of this type, the load capacity is 16 A with a frequency of 50 Hz for an alternating current of 230 V. But some negligent manufacturers use poor-quality disconnect devices in their efforts to save money. In them, the conductors are not designed for a large starting current because they differ in small cross section.

Sockets-timers of questionable production should not be used to control one and a half kilowatt water heaters and other high-power consumers

When choosing a socket with a timer, you should focus on a number of parameters:

1. The maximum programming time or the range of time intervals.
2. Accuracy of the device clock and maximum time limit for switching operations.
3. The discrete setting of the switching time (the parameter can be from two seconds to half an hour).
4. Load capacity of the device (which maximum permissible switching currents).
5. Maximum number of switching programming per day.

All specifications  registered in the passport to the product. Please note that the active and reactive load of the equipment connected through the switch must not exceed the values ​​indicated by the manufacturer in the documentation attached to the outlet. Example: when the heating device is turned on with a power of 5 kW, the current will be approximately 25 A, which would be fatal for a 16 amp socket.

Each of these outlets is equipped with parameters that provide the necessary level of protection. On sale there are models equipped with a dust and moisture repellent body, equipped with protective covers and curtains.

When choosing a model, pay attention to the number and duration of the on / off intervals they are calculated

When planning to use outdoor switches, it is worth choosing products with a waterproof enclosure, the IP parameter of which is 44, 54 or 65. Guided by the principle - the higher the IP the better protection. Due to the thermal and moisture-resistant coating of housings, such devices are capable of operating in the temperature range from -10 to + 40 ° C.

Choosing a socket for a home where there are small curious household members, it is worth considering the option of purchasing a device equipped with the function "protection from children". Devices of this type are equipped with special valves, which prevent direct contact of foreign objects with electrical contacts.

If you focus on manufacturers, then the Russian market is most popular products of leading brands: Legrand, ABB, Berker, Wessen, Schneider Electric.

Of the more budget models, it is worth considering the products of the trade marks "Feron Company" and "Expert", which are in no way inferior to European producers in quality

The price range of automatically disconnected outlets is wide. The cost of mechanical models starts from the mark of 250 rubles and above. Digital automatic outlets-timers will cost from 500 rubles and above.

Features of the installation of switch-off sockets

To program a mechanical outlet you need to perform a number of manipulations:

1. By rotating the wheel, set the current time.
2. Orienting on the dial, with the help of segments set the set time to turn on the device.
3. Put the device in motion and connect it to the power supply, so that it starts to carry out the task assigned to it.

The principle of installation of a mechanical outlet with a timer for disconnection is identical.

The process of programming a socket with an electronic timer is more complicated.

Before using the device, it is necessary to study the instruction to it in detail, because the identical switches can be very different in the way they are programmed

The programming of the device is performed in this order.

1. The device is connected to the mains so that the built-in battery is recharged. The charging time depends on the manufacturer. It is indicated in the passport.
2. Activate the inclusion and expose the current time and day of the week, as well as the way they are displayed. If necessary, clear the device memory using the "Master Clear" function.
3. With the help of the 24/7 programming system, a timer is set. When setting the on and off times, you can put it every day or any other combination.
4. To finish setting the mode, press the "Time" key again and go to the display with the current time.
5. Plug the socket into the mains and connect the load to it.

When setting up, you need to make sure that the specified programs are not overlapping each other. Otherwise, if you set two mutually exclusive settings, the priority will be the one that corresponds to the "Off" option above the "On" setting.

So, for example, by setting the first unit to turn on the outlet for the period from 12 to 22 hours, and in the second on the same day, but from 15 to 19 hours, the timer will turn on in 12 days and turn off at 19 pm, that under the program of the second block he must work until 22:00.

In general, setting up automatic outlets does not cause any particular difficulties. For a more correct operation of the devices, one should only remember to switch the clock in them to the winter and summer operation mode.

An automatic socket with a timer is an inexpensive and at the same time an effective variant of automation of power supply modes for private housing. The purchase of a digital device is justified when you really need to set up complex algorithms and automatically perform a weekly program. When performing the same schedule daily, you should not overpay, limiting installation mechanical device  with a daily electromechanical clock.
