-Turn on the power relay to pull in and off at a fixed cycle of 1-10s. Specifically: after the relay is supplied with 12v power, the relay will not immediately sink. The state of the relay output is: normally open and common conduction, normally closed and public disconnected; wait until the delay is 1-10s (can be adjusted), the relay Released, at this time, the state of the relay output is: normally open and common open, normally closed and common conduction; as long as the module is continuously powered, this state will remain closed and released at a fixed cycle of 1-10s.
-Delay time is adjustable, (0~10 seconds).
-Increase the potentiometer to increase the delay time.
-Increase the capacitance C1 to increase the delay time.
-With input power indicator.
-With relay pull-in indicator.
-Can control AC 220V/10A equipment. (Maximum control device 2000W).
-With relay freewheeling protection.
-Delay time formula: T = 1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds.
