The Pilz PNOZ 1 safety relay (model 775630) is a proven solution for implementing reliable emergency stop and guard monitoring in industrial automation. Designed for 110–120 V AC control panels, it provides three normally open safety outputs and one normally closed auxiliary contact to switch loads and signal status in machine safety circuits.

With flexible 1- or 2-channel input wiring, the PNOZ 1 supports straightforward integration of E‑Stops and safety gate switches. Operating as a standalone module with dependable relay contacts, it omits cross-short detection across contacts, making it well suited for simple, clearly defined safety functions where external diagnostics are handled elsewhere in the system.

For OEMs, panel builders, and maintenance teams seeking dependable performance with minimal complexity, this unit combines clear functionality with fast commissioning to keep downtime low and productivity high; it’s a practical choice for new installations and retrofits alike and is supplied with a 1-year warranty for added assurance during the first year in service.
