【brief introduction】
1. Size: 6.8CM*2.1CM
2. Main chip: NE555
3. Working voltage: DC 12V
4. Features:
1. Turn on the power, and the relay will pull in with a delay (this module only has a delay pull function, and there is no delay disconnect function, unless the power is turned off). Specifically: After power-on, the relay will not immediately absorb and the state of the relay output terminal is: normally open and public disconnect, normally closed and public conduct; after the delay is 1-10s (the delay is adjustable), The relay is in and at this time, the state of the relay output terminal is: normally open and public conduction, normally closed and public disconnection; as long as the module is continuously powered, this state (relay suction state) will always be maintained. Test phenomenon: After power-on, the red power indicator light is on. After a delay of 1-10S, the relay is activated, and a “click” sound will be heard, and the blue relay and indicator light is on.
2. The delay time is adjustable, (0～10 seconds)
4. Increasing the potentiometer can increase the delay time
5. Increasing the capacitor C1 can increase the delay time
6. With input power indicator
7. With a relay pull-in indicator
8. It can control AC 220V/10A lower equipment. (Control equipment 2000W)
9. With relay freewheeling protection.
10. Delay time formula: T=1.1RC. For example: capacitance 100uf resistance 100K T=1.1*100000*0.0001=11 seconds
