24Vdc powered 0.1 second to 4 minute delay timer module with mains rated relay output. Delay is user adjustable using two time scales. When activated the relay turns on for the user-set time period. Timer is activated by the Start input (using for example a push button or relay contact closure). The timing cycle is non-retriggerable and will be completed regardless of further Start inputs or if the Start input remains closed after activation. A new timing cycle can only commence once the current timing cycle has finished.
