Mains powered 1 to 180 second retriggerable delay timer module with a mains rated relay output.
With power applied to the board, the timer is activated using the Start Input (using for example a volt-free push button or relay contact closure).
On activation, the relay turns on for the user-set delay time. Any further triggers received while the relay is active will restore the full delay time (non-cumulative) without interrupting the relay. If another trigger is not received before the delay timeout is reached, the relay will turn off and the board resets ready for a new trigger signal. The Start Input must go open circuit and be closed again to register a fresh trigger input.
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.
