NE555 0-10 sec Adjustable Timer 10A/250V Relay Module Arduino

Relay module with timer - 0-10 seconds - contacts 10A / 250V AC or 10A / 30V DC.

Relay module with adjustable timer in the range from 0 to 10 seconds. The system works on a simple principle: after supplying 12V power to the input, it starts measuring the set time and when this is over the module turns on the relay. Time after which the module is to turn on the relay is regulated by a potentiometer soldered on the board. There are three terminal blocks at the output of the relay, so you can easily connect the wires. By default, the relay in the rest state short-circuits the middle pin 2 to pin 1 (NC), when the relay switches on, so it changes the position of the contacts when pins 2 and 1 are open and the relay closes the circuit between pins 2 and 3. And when it turns off, it returns to the default position that is, it closes pins 2 and 1 and pin 3 is disconnected. Thanks to this, the user has the option to turn on the device when the relay is turned off (pins 2 and 1), or when the relay is turned on (pins 2 and 3).
