The delay time is adjustable(0 to 10 seconds)
Increasing the potential can increase the delay time
Increasing the capacitor C1 can increase the delay time
With input power indicator
With relay indicator
Can control AC 220V / 10A about equipment. (Maximum control equipment 2000W)
With freewheeling protection relay.
The delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf 100K
T = 1.1 * 100000 * 0.0001 = 11 seconds
