Omron G2RV-ST500 AC/DC24 PNP Terminal Relay, Current Lifecyc

The Omron G2RV-ST500 AC/DC24 is a PNP terminal relay, part of the G2RV series, with a 24 VAC/DC coil. It is designed for interface between a controller (PLC) and field devices, providing a clean signal path in a compact, DIN-rail-mountable package. The PNP output means it switches the positive side of the load — common in modern PLC systems that source current. Check the shield first if you're chasing a phantom fault; this relay isolates the field wiring from the control logic, but the signal integrity depends on proper grounding at the panel end.
