Features:
1, The relay time delay and power supply are connected. Specifically, as follows: for a 12V power supply to the relay, the relay does not immediately activate and absorb power; the relay output status is: normally open and publicly disconnected, normally closed and publicly conducting; Wait for a 1-10 second delay (adjustable), then the relay activates and absorbs power. At this point, the relay output status is: normally open and publicly conducting, normally closed and publicly disconnected; As long as the module power is continuously supplied, this state will remain.
2, The delay time is adjustable (0 ~ 10 seconds)
4, Increasing the potentiometer increases the delay time
5, Capacitor C1 can increase the delay time
6, With input power light
7, A relay and indicator lights
8, Controls AC 220V / 10A devices. (maximum control equipment 2000W)
9, Equipped with relay protection.
10, The delay time formula: T = 1.1 RC. For example: 100µF capacitance, 100kΩ resistance, T = 1.1 * 100000 * 0.0001 = 11 seconds
