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!
This versatile relay module has two independent timers built in to it so it can be set up to switch the relay contacts on and off in a variety of ways.
Handy 1, 2, 4, 8, or 16 channel relay which boast 'opto isolation' of input to output for added safety and to ensure circuits are truly electrically isolated.
The Mini HRM402 Voltage Booster measures just 64mm x 35mm so it's tiny enough to fit in other equipment and actually contains a built in LED voltmeter.
This module allows remote control of third party electrical equipment/systems via the Zip Range/alienDVR and our Free ZipVision/alienVision software.
