The cyclic time relay is a fully assembled electronic module designed for controlling electrical loads in a repeating ON / OFF cycle - work, pause, work, pause, continuously.
When power is applied, the POWER LED lights up and the relay switches ON, indicated by the ON LED, entering WORK mode. After the preset work time expires, the relay switches OFF, the ON LED turns off, and the device enters PAUSE mode. Once the pause time elapses, the cycle repeats automatically.
The work time and pause time are adjusted independently using two separate trimmer potentiometers. Each time interval can be set from 1 to 120 seconds or minutes. The selection between seconds and minutes is made via a jumper with the power disconnected.
This module is suitable for automation systems, fan and pump control, lighting, signaling systems, and other applications requiring periodic switching.
