Delay On-Off Relay

This mini relay module can either open or close contacts at a 1-20s adjustable delay when you apply 12V to it. It's so tiny at 30x54mm it can even be housed in other equipment.

Providing a perfect solution to delay the switch on or switch off of lights, door locks, bells, buzzers and so on, at such a low price it's an absolute bargain for any professional installer's toolbox.

If you need a delay on or off longer than 20 seconds then look at our 10 function relay (HRM250) with a delay of up to 10 days!
