Product Description

The PNOZ s4.1 safety relay is a robust 24VDC safety relay designed for industrial automation, offering 3 normally open (NO) and 1 normally closed (NC) safety-rated contacts. It operates on a 24VDC power supply (±10% tolerance) and supports direct connection to safety devices via dual-channel inputs for reliable monitoring of emergency stops, light curtains, or interlocks. With an operating temperature range of -20°C to +55°C, it excels in harsh environments typical of manufacturing, machinery, and material handling systems. The module can interface with up to two expansion units via its integrated terminals, simplifying system scalability. While it lacks built-in communication interfaces, its strengths include compact design, high fault tolerance, and compliance with EN ISO 13849-1 safety standards. Key features include cross-circuit detection, manual reset capability, and LED status indicators for diagnostics. However, it does not support advanced networking protocols, limiting its use in complex networked safety systems. The relay’s fail-safe architecture ensures immediate shutdown upon detecting faults, minimizing downtime and enhancing personnel safety.
