Resideo RT850T-347 Relay 320788-703 protecting sensitive HVACR electronics fromThe Resideo RT850T 347 Relay is a heavy duty solid state relay engineered specifically for controlling line voltage resistive loads in electric heating applications. Featuring a built in 24 V transformer, this unit simplifies the control of baseboard heaters, radiant ceilings, and duct heaters from a low voltage thermostat. The TRIAC switching ensures 100% silent operation, eliminating the mechanical clicking common in traditional contactors, making
