Time relays - a device in which the relay element responsive to a control signal with a time delay. Delay relay is controlled by the impact of the rate of change of a physical quantity affecting the relay element. The accuracy of billing time delay relays, mostly on a scale analog potentiometer.
In applying the multi-band relays, the range is first determined, and then within a given range delay exhibited smoothly potentiometer. Scale potentiometer relay has a gradation in the percentage of 5% to 100% of the final value of the time range.
It should be borne in mind in the timer is no possibility of exhibiting the minimum time delay relay is less than 5% of the final value of the range, for example, for the range of 1:00 to set the time delay can not be less than 3 minutes.
Despite the fact that the time switch equipped stable reference oscillator, when the ambient temperature changes the temperature dependence exists a time delay. In the application of the device in a wide temperature range, this relationship should be taken into account.
Supply voltage timer should be set by the manufacturer within. Otherwise, the accuracy of the relay is not guaranteed. Note that at low power timer is heated during operation. When seated firmly in the closet or under high temperature environment is necessary to control the resulting thermal conditions.
To increase the life of the relay is always necessary to load the relay contacts as small as possible shock. If necessary, a very large security operation mounted on the exit timer powerful intermediate relay. Relay vemeni included applying power or through the gate contact - Read and understand the connection type. Upon completion delay timer needs some time to recover, as a rule, this time is in the range of 50 ... 75ms. During this time span, the relay does not respond to any input control signals that should be considered when "often" turn on the timer.
Timer, like any relay can be divided into categories depending on the physical nature of the input and output signal. Most commonly used in the art electric control timers for communication of electrical signals.
Fields of application timers - timers.
Coordinating with timers heating and heating
Control of electric heaters - oil radiators, heaters, convectors, fan heaters, electric heated floors, IR panels.
Check the functioning of gas boilers.
Control of the electric water heating equipment - boilers.
To control the time of the lighting
On and off the street and house lighting.
Enable or disable lighting indoors.
On and off illuminated signs and lighting displays, billboards, signboards.
For aquariums and terrariums.
Enable or disable lighting aquariums and terrariums.
On and off the compressors in the aquarium, to saturate the water with oxygen at a certain time.
On and off electric heaters, humidifiers and many other instruments of climate control in aquariums and terrariums.
Feeding fish, reptiles and other denizens of the time.

For the infield and agriculture.
Irrigation - including a pump for watering plants in opredennyh period.
For greenhouses - switching on and off lighting, heating, saturation humidity allows you to create an optimal climate for the growth of plants.
To ensure that the effect of presence.
Enable - off lights and other electrical appliances in random order gives the possibility of organizing a visible presence in the room of people that discourages "uninvited" guests when you're not home.
