Product Description

The **PNOZ s4 Safety Relay** is a robust safety relay designed for industrial applications, featuring a 3NO+1NC contact configuration (3 normally open and 1 normally closed safety contacts). It operates within a wide voltage range of 48-240V AC/DC, making it suitable for diverse global voltage standards. The relay integrates forced-guided contacts for reliable fault detection and supports hardwired safety circuits without requiring additional communication interfaces. With a compact design, it enables direct mounting in control panels and can interface with multiple safety devices via its configurable inputs. Ideal for machinery safety systems, automated production lines, and hazard control, it offers high immunity to electromagnetic interference and operates within -20°C to +55°C. Advantages include simplified integration, rugged construction, and compliance with IEC/EN 60947-5-1. Limitations include no built-in communication protocols. Screen size and battery capacity are not applicable as this is a hardwired relay. Its safety-focused design ensures rapid shutdown in fault conditions, critical for protecting personnel and equipment.
