CI0037 - 12Vdc Delayed-On Timer Relay Module (2 to 45 Minute)

2 to 45 minute 12Vdc "Delayed-On" timer module with a mains rated relay output. The user-set delay time starts when power is applied to the board but the relay remains off. On completion, the relay activates and remains on until the modules power supply is removed. The process will be repeated each time the board is powered up.

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

The timer can be modified to activate using the Start Switch input (push-button contact closure). The timing sequence with 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.

A 1 to 180 second version of this board is available (Order Code CI0036)
