Mains powered 1 to 180 second retriggerable delay timer board module with a mains rated relay output.
The timer is triggered by closing the low voltage Start Input (using for example a volt-free push button or relay contact closure).
When triggered, the relay turns on for the user-set delay time and then turns off at timeout (irrespective of the Start input being open or still closed). The Start Input must go open circuit and be closed again to register a new trigger input.
If a new trigger input is received while the relay is active, the full delay time is restored (non-cumulative) without interrupting the relay. When no new trigger input is received for the entire duration of the set delay time and timeout is reached, the relay will turn off and the board resets ready for a new trigger signal.
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 relay is active.
