The Omron G9SB-200-D AC/DC24 is a safety relay rated at 5 A, with a 24 VAC/DC coil. It sits in the G9SB series, built for machine safety circuits where a forced-guided contact set is needed to monitor and interrupt the safety path.
The 5 A rating governs the switching capacity of the safety contacts — sized for control-circuit loads like contactor coils, solenoid valves, and indicator lamps in a safety loop. The 24 VAC/DC coil means it pulls in on either AC or DC supply, which simplifies panel wiring when you're mixing control voltages. No separate coil-supply rectifier needed.
