The Omron G2R-1-SNI AC110(S) is a general-purpose relay with a 110 VAC coil, SPDT (1 form C) contact arrangement, and silver cadmium oxide contacts. The SNI suffix indicates the inclusion of an LED indicator and a test button, making it useful for panel troubleshooting without needing a meter to verify coil state.
What the Ratings Mean for Fit
The 110 VAC coil is the primary fit constraint — it will not pull in on 24 VDC or 120 VAC without a dropping resistor or transformer. The SPDT contacts (common, normally open, normally closed) handle general-purpose switching up to the relay's rated load; silver cadmium oxide gives good arc resistance for moderate inductive loads like contactor coils or small solenoids. The LED indicator draws negligible current from the coil circuit and confirms the coil is energized at a glance.
