The Omron G7Z-4A-02Z-R DC24V is a safety relay from the G7Z series, offering four normally open contacts (4PST-NO) with a 24V DC coil drawing 154 mA. It is used in safety circuits where fail-safe isolation is required—common in machine guarding, press controls, and emergency-stop chains. The screw terminals accept 8 pins, so wire up the four NO contacts per the nameplate diagram. No push-to-test button, so verify coil pickup separately if bench testing.
