It supports dual-channel input wiring with detection of shorts across contacts to maintain high diagnostic coverage in safety-critical applications. The relay provides both standard and intrinsically safe outputs, enabling reliable switching of safety circuits within ATEX-regulated zones. Designed with integral screw terminals and a robust enclosure, it supports secure installation in industrial control panels operating on 230 VAC. Key Features PNOZ EX ATEX-Certified Design: Developed for intrinsically safe applications in hazardous environments where explosion protection is required. Dual-Channel Intrinsically Safe Inputs: Supports two-channel safety wiring with short-circuit detection to enhance fault detection and system reliability. Multiple Safety Outputs: Provides 3 normally open and 1 normally closed safety contacts for flexible safety circuit control. Additional Intrinsically Safe Outputs: Includes 2 intrinsically safe normally open outputs for direct connection to IS-rated field devices. Monitored Start Function: Ensures controlled and supervised restart behavior after safety events. High Electrical Ratings: Safety contacts support up to 240 VAC and 4 A, allowing direct switching of industrial contactors. Industrial Wiring Interface: Fixed screw terminals support conductor sizes from 24 to 10 AWG for secure and vibration-resistant connections. The 774100 delivers the reliability and precision required for intrinsically safe emergency stop and safety gate monitoring in hazardous industrial environments.
