Resideo RA89A1074 Relay Els PW 17895 it provides consistent millivolt output

it provides consistent millivolt output to the safety shut-off valve

eliminating the need for step-down transformers

reducing field diagnostics and ensuring the furnace operates within its designed static pressure and temperature rise parameters

it should only be used in 120V applications designed for carbide resistance

tech-standard practice is to wrap the monitored conductor through the center window multiple times to increase the induced current and improve sensor resolution

Resideo RA89A1074 Relay Els PW 17895 it provides consistent millivolt outputThe Resideo RA89A1074 Relay is a reliable, industry standard solution for technicians managing hydronic systems that require seamless interfacing between low voltage controls and 120V line voltage equipment. Built with a 120Vac primary voltage transformer and a 24Vac coil, this switching relay allows a standard 2 wire thermostat to drive heavy duty components like circulator pumps, fans, or boiler ignition circuits. Its SPST switching action ensures
