The Omron G7Z-4A DC24 is a 4-pole normally open (4PST-NO) power relay from the G7Z series, classified as a safety relay for industrial safety circuits. It pulls 154 mA at 24 VDC coil voltage, a moderate draw that fits standard 24 V control loops. The dielectric isolation is rated for 4000 V AC between coil and contacts, and 2000 V AC between contacts of the same polarity, meeting the isolation requirements for safety-related stop circuits and light curtain interfaces.
The G7Z-4A DC24 is catalogued with a mature lifecycle stage — stable production, no phase-out or last-buy window currently flagged. For a category sourcing planner, this means the part remains a safe BOM line for ongoing builds, with no forced replacement horizon.
Connection is via screw terminals on an 8-pin base. There is no push-to-test button, so manual actuation during commissioning requires a separate test circuit or external pushbutton.
To close: if your BOM calls for a 24 VDC safety relay with four normally open contacts and screw termination, the G7Z-4A DC24 is a direct match. Submit an RFQ with your target quantity and delivery schedule.
