NT90-AC220-10X Power Relay AC 220V Coil 120 VAC 30A 40A SPDT(1NO 1NC) with Flange Mounting and 10 Quick Connect Terminals Wires Mini Relay(Pack of 2pcs)

Exactly what I needed and works great! I installed it inside an old Roper 18,000 BTU wall AC unit that I have had for 28 years or more. The thermostat was stuck on so the compressor ran all the time. The terminals were the same as what was on the internal unit thermostat so I had to just plug them onto the relay and run a pair of low voltage wires out of the unit into an external thermostat I had already with a 12 volt wall wart supply in series with the thermostat wire. Yes, You can call it a rig but it works very well! Love that I now have a true digital thermostat control on an ancient reliable unit. (Except the thermostat, but who expected any of it to last 28+ years!) Let see how many more years I can get out of it. Heck, It might outlast me! LOL!

They worked great

Exactly what I needed. 120vac coil to control 120vac switch. Using it in application to turn off light when power is applied. Relay has both NC (Normally closed) and NO (Normally open) outputs.

The cables that come with it are worthless, (there aren’t enough for one relay, let alone two) but otherwise works great!

It was great

In the picture you will see 2 relays and 5 wires for each relay. What was sent to me were 2 relays with 3 wires total. This relay uses 2 different sizes of spade connectors, Standard width for the relay outputs and narrow for the coil connections. The relays came with only 3 wires, a black, red, and blue wire and all of them had the narrow connectors. Like I said before, it was not 3 wires per relay, it was 3 wires total. This would allow me to connect one of the relays coils but nothing for the relay output connections and not enough wires to even connect the second relays coil, never mind the second relays outputs. What good is a 2 pack of relays if they don't come with the connectors required to use them. I could order or go to one of the big box stores to get the required connectors but why should I have to do that when the image shows it coming with all of the required wires. These will be sent back because as they have come, they are useless without added cost. Sadly, this is an issue when ordering items on-line. You don't always get what you ordered or expected. Fortunately for me, I saw this prior to the return deadline.

I use one of these with a smart plug to turn on the fireplace with a standing pilot thermocouple gas valve with Alexa. Just unplug the blower and replace with a Smart Plug. Insert a multioutlet adapter. Plug in the blower motor. Mount the relay near the manual on/off switch. Attach the connectors to the relay Normally Open contacts. Attach a 120-volt cord to the relay coil. Set up Smart Plug as "Fireplace" and say Alexa turn on fireplace. This will save you hundreds of dollars. I bought two, one for a spare. Another option would be to wire the relay contacts in parallel so the fireplace can be turned on in a power outage if desired.
