NE555 Time delay relay module Time delay power switch 5V automotive electrical monostable switch

Product features:
1, switch on the power relay delay suction.
Specifically: After supplying 12v power to the relay, the relay will not absorb and, the state of the relay output is: normally open and public disconnect, normally closed and public on-off; Wait until the delay of 1-10s (can be adjusted), the relay suction and, at this time, the
relay output state is: normally open and public conduction usually closed and public disconnected; This status remains as long as the module is powered on. 2, adjustable delay time, (0~10 seconds)
4, increase the potentiometer can increase the delay time
5, increase the capacitor C1 can increase the delay time
6, with input power indicator
7, with relay pull indicator light
8, can control AC 220V/10A equipment. (Large control equipment 2000W)
9, with relay continuous current protection
10.
Delay time formula: T- 1.1RC. For example, the capacitor is 100uf and the resistor is 100KT
= 1.1 * 100, 000 * 0.0001 =11 seconds
