12Vdc powered 1 to 180 second delay timer module with a mains rated relay output. When activated the relay turns on for the user-set delay period.
The timer is activated 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. Once finished, a fresh trigger signal is needed to start a new timing period.
An optional "Instant-On" mode disables the trigger input and commence the delay countdown immediately power is applied . The relay will stay on until the user-set time period has elapsed. The power must be removed and reapplied for a fresh countdown to commence.
The delay period is adjustable from 1 to 180 seconds using the onboard potentiometers (header pins allow the use of user-supplied external potentiometers if required).
An LED indicates that the timer is in operation. The board is reverse polarity protected.
