12Vdc Delayed On Timer Relay Module, 2 to 45 Minute

12Vdc powered 2 to 45 minute DELAYED-ON timer module with a mains rated relay output.

The user-adjustable delay time starts when power is applied to the board but the relay remains off. The relay activates on timeout and remains on until the modules power supply is removed. The process is repeated each time the board is powered up.

The delay period is adjustable from 2 to 45 minutes using the onboard potentiometers (header pins J1 allow the use of user-supplied external potentiometers if required).

The timing sequence is non-retriggerable and will be completed regardless of further trigger signals or if the contacts remain closed after activation. Power must be removed and reapplied to reset the timer.

Board can be modified to push button operation by removing C3 and adding a switch of your choice to jumper J2 (see manual for details).
