The 2904958 is a safety relay designed for monitoring emergency stops, safety doors, and light grids in safety-critical systems. It supports both 1 and 2-channel operation with automatic activation and is powered by a 24 VDC supply. This electromechanical relay provides two undelayed, safety-related N/O enabling current paths with a limiting continuous current of 6 A. Housed in a narrow 6.8 mm wide enclosure for DIN rail mounting, it is designed for operation in ambient temperatures from -40 °C to 55 °C. The device achieves high safety levels, including SILCL 3 (IEC 62061) and PL e, Category 4 (ISO 13849-1), making it a reliable component for industrial machine safety applications.
