Electromagnetic Power Relay, 14-Pin 5 AMP 12V DC Relay Coil with Socket Base, LED Indicator, 4PDT 4NO 4NC - MY4NJ [Applicable for DIN Rail System]

I like the din rail mounting system, the sockets are easy to wire and the led indicator is nice for diagnostics and just looks good.

These work well, but if you want the LED indicator to function properly, you'll need to be aware of the coil polarity, which is typically not a concern. The provided socket/terminals are great because they allow connection to the relay without soldering, which is what caused my previous relay to fail. Relays are somewhat fragile and heat-sensitive, and this is a great solution.

AC coil relay works great at 120V, and the status LED is nice visual confirmation that it's working. The output has two separate circuits, which was useful for my particular use. I'm detecting if AC power is lost, feeding one output into a Zigbee contact sensor, and the other output feeds into a 120V UPS output which powers a light tree. I added a fuse to the coil side in case if the coil ever shorts the fuse will blow instead of burning up some wire.

These are quality relays. The ice cube fits securely into the base, actually hard to get them back out. I could tighten down the set screws tightly without stripping them out. Even comes with a strip of din rail for mounting.

I used the 110V 8 pin relay to make a perfect and fast power out transfer to battery backup for my diesel heater. You cannot let the power stop for this baby when its running or the mainboard will melt.

I had planned on mounting on a din rail and they will work great for me but upon examination I was looking for holes in the base to mount without a din rail and there is none These can not be mounted directly to a flat surface they MUST have a din rail. Good product except for the missing the secondary mounting option

This 8 pin relay was the perfect solution for my inline duct fan install project. I purchased the 120v 10A relay. For those of us who aren't Master Electricians I have attached pictures explaining my install. After hours of internet research I pieced together exactly what I needed to do for my particular install, as I wanted the inline duct fan to turn on and off whenever my HVAC system was running - rather than having it run all the time or having to operate it by a switch/remote. You should be able to adapt your particular needs using this relay. I ordered the 2 relay kit because it was such a great value. It included 2 relays and the mounting bar needed, plus if my relay ever fails I will have an immediate replacement on hand! I hope this helps my fellow DIY jobbers get their project done.NOTE: for those who need to know what is the amp draw of this coil, I found the manufacturer data spec sheet. This relay coil will draw an average of .028 Amps derived from the Spec Sheet rating of Coil Current of 27.1 milliamps.

Fit as expected, fixed the problem, easily ordered.
