After the relay has been supplied with 9V, the relay does not pick up immediately.
The time can be set between 1 and 10 seconds.
The status of the output connection of the relay is: normally open
When the set time has elapsed, the relay picks up.
As long as the module is supplied with power (9V) without interruption , this state is maintained. If the 9V power supply is interrupted, the relay opens again.
- Adjustable delay time (0-10 seconds)
- Increasing the potentiometer increases the delay time
- Increasing the capacitance C1 can increase the delay time
- Status lamp for the relay status (blue LED lights up when the relay is switched on)
- Status lamp for the power supply (9V) on the relay
- Controllable current AC 220 V / 10A. (Maximum control power 2000W)
