Electromagnetic Power Relay, 8-Pin 10 AMP 12V DC Relay Coil with Socket Base, LED Indicator, DPDT 2NO 2NC - MY2NJ 2PCS [Applicable for DIN Rail System]

Great little relays for many projects rated at 10A contact. DPDT. I got the 24vac coil for a RV thermostat conversion. With these i am converting my Coleman Mach roof a/c and suburban floor heater so i can use a residential style thermostat. A RV uses a 12v system and unless the thermostat is battery operated it can’t be used in the situation and definitely won’t have WiFi capability. I am using a Honeywell Redlink for my personal preference but these relays would allow you to use Nest or Ecobee or Sensi If you desire. Now my project like I said may only work for the basic Coleman unit.

It's working perfectly

Worked great is exactly as described

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.

Did not need, or want the relay base, however, the unit works as expected.

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.

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.
