The G9SE221T30DC24FOROEE is a DIN-rail-mount safety relay from the G9SE series, configured with 2 normally-open (2NO) safety contacts and a PNP transistor auxiliary output. It switches 5 A on both AC and DC loads, runs on a 24 VDC supply, and responds within 15 ms — fast enough for most emergency-stop and light-curtain circuits.
The 2NO contact arrangement suits dual-channel safety circuits — two independent paths for the safety function, each rated to 5 A. The PNP transistor auxiliary gives a status signal back to the PLC without loading the safety contacts. Screwless terminals (spring-cage) speed panel wiring and hold up under vibration. IP20 keeps the relay safe for enclosure interiors; no washdown or dust protection. Electric life is rated to 50,000 cycles and mechanical life to 5 million — the electric figure governs in high-duty applications like repetitive press or robot cell cycling.
