Electromagnetic Power Relay, 8-Pin 10 AMP 24V AC Relay Coil with Socket Base, LED Indicator, DPDT 2NO 2NC - MY4NJ 2PCS [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.

Ordered these for a timer project I was working on. The quality of the parts received appear on par with any industrial ones I have worked with over decades of experience in electronics. Very nice also that the base is lighter colored and so pin numbers are easily readable. The relay has an internal red light that comes on when it is activated. To top off the deal, it comes with a mounting rail, screws, and retainer clips as well and is packed in a reusable clear hard plastic case.. Very competitive deal!

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.

Best relay block I've seen so far,etched terminal blocks numbers and schematics are clear and simple.I ordered and open it thinking I was going to use it turned out the photo cell I ordered had an isolated set of contacts eliminating the need for a relay.However I keep it just because I will use them some day and they look like good quality part (rare now in days)Yes I recommend this parts.

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

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 made this convoluted wifi add-on for my dumb sprinkler controller, which this relay is a part of. I needed a 24V AC relay so that I can detect the sprinkler is on or not (albeit only one zone). I did not use the DIN rail that came with it, rather the spade connector directly to the terminals. I managed to broke off one of the terminals so I soldered the wire directly to the short remaining end. As to which terminals to use - you can see how this relay operates from the side, an advantage of having clear plastic cover, to figure out whether you want NC (normally closed) or NO (normally open). I even used the plastic box that came with it as an enclosure. Pretty satisfied with this relay.

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.
