OmronLY2-AC24 (Pack of 2) General Purpose Relay, 53.8 mA at 50 Hz and 46 mA at 60 Hz Rated Load Current, 24 VAC Rated Load Voltage

Fit right into the sockets on my Argo Industries AR861 switching controller. I had some bad wiring that caused massive relay chatter to the point they exhausted their life cycles prematurely. I fixed the wiring and then replaced the relays with these two. An effortless fix. Pulled the old relays, plugged these in and all is well. Phew!

Boiler fired right away after swapping the old burned fuses with these new ones.

Had a relay start to fail in our furnace control unit - this is an exact replacement. Plug and Play..
