Description
Time relay – Blinker at start of pulse , Blinker at start of pause cyclic relay – symmetrical / asymmetrical cycle
A cyclic relay or cyclic time relay is used to periodically turn on electrical loads (such as lights, fans, etc.) or to energize control signals in automatic monitoring or control systems (such as turning on an emergency flashing light or audible signal). This cyclic timer can be useful for organizing automatic ventilation processes, opening and closing windows, periodically switching on heating or ventilation, for lighting or rotating advertising signs.
If you configure the relay so that its on and pause times are symmetrical, it can be used, for example, to switch on certain electrical appliances gradually in the event of current/power limitations (heaters, heat generators). The presence of a switching output contact makes it possible to start the cycle either pulsed or with a pause.
The time relay is mounted on a standard 35mm DIN rail
