The SRB211ST (V2) safety relay is a compact and reliable solution for monitoring safety-critical circuits in industrial applications. It is ideally suited for use with safety door systems, emergency stop buttons, safety light curtains, and pull-wire switches. The relay is designed to meet safety requirements in compliance with EN ISO 13849-1 and EN IEC 62061, offering protection up to SIL 3 and PL e. Integrated features such as wire break detection, cross-fault detection, and ground fault detection ensure maximum operational safety.

The housing is made of durable, glass-fiber reinforced plastic, providing robust protection against both mechanical and electrical stress. With six status LEDs, the device provides clear feedback on the operating status. The relay outputs are designed for STOP categories 0 and 1, making the device flexible for various safety concepts.

The safety relay supports both automatic and manual reset functions. Its compact size of only 22.5 mm width allows for space-saving installation on DIN rails. Thanks to its integrated protective measures against interference and a high mechanical lifespan of over 10 million switching cycles, the device ensures long-term reliability.
