LY2-AC24 General Purpose Power Relay, 10A Contact Rating, 46Ma at 60hz Rated Load Current, 24 VAC Rated Load Voltage

This was an exact part match for the existing relay that was clicking on and off like crazy. The failing relay was causing a unpleasant leak from sudden overpressure that had me baffled. Once I investigated the clicking noise I could see the arcing inside the original relay. To repair, I just disconnected the power using the circuit breaker, then pulled out the old relay with my hand, and slid the new relay into place. It really was a trivial repair with dramatic results! No more over pressure leaking, and the heating to that room is now more reliable.

I go through these every few years; they control pumps for a hydronic system. Good relays (industry standard) and I'll keep buying them!

I did not buy these for a heating system. I made a custom irrigation system master valve relay switching system to operate one master valve from three different irrigation controllers. Worked wonderfully teamed up with Amazon item # B005T67OFE. I posted a picture. Take note that there is no pin schematic included with the relay other than the hard to read rela. Granted that can be figured out with an ohm meter or download the pin schematic. (datasheet(dot)octopart.com/LY2-AC24-Omron-datasheet-10910099(dot)pdf) I have 24VAC on the coil and switching 24VAC at .3 amps. Quite low because the switch is rated at 10 amps for 120 volts.

What can I say it works in my Arco zone controller for my heating. My old relay was not activating all the time and now with this replacement it does. For $12 my hydronic system is running right again. Quality looks pretty good, we will see about longevity but I suspect it will last as long as the original, 12 years.

These are direct pin replacements for the heating controller at my brother's home and they work as expected. We bought extras just to have on hand.

Relay was exactly the brand and quality I was hoping for. Quick service and I didn't end up with an inferior copy of the original brand. Very pleased with the service. I would be happy to deal with this company in the future.

Perfect replacement with good price.

Works great. replaced the furnace relay that furnace co wanted $50 for. It is merely a standard LY2 footprint DPDT relay. I got this model with a 24v coil to switch the 110V furnace circuits. FYI although I bought this Omron product I could have bought ANY LY2 footprint relay with a 24V coil.
