24Vdc powered 2 minutes to 3.5 hours 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.
An optional INSTANT-ON mode disables the Start input. In this mode, the the relay turns on and the delay countdown commences immediately power is applied to the board. The relay turns off when the user-set time period has elapsed. Power must be removed and reapplied for a fresh countdown to commence. Instant-On mode is set using a header jumper not included (Order Code JUMPER-RED).
The delay period is adjustable using the time scale switch and onboard potentiometer.
An LED indicates that the timer is in operation. The board is reverse polarity protected.
