Schmersal SRB-EXi safety relay modules

The Schmersal SRB-EXi safety relay modules now meet the requirements for use in hazardous areas since obtaining IECEx certification.

The SRB safety relay is suitable for secure signal analysis of emergency stops and safety monitoring equipment up to safety category 4 or PLe. This device is capable of monitoring safety devices such as E-stops, pull wire switches, guard switches and non-contact safety sensors installed in hazardous environments.

Short circuit, wire break and earth connection detection are all supported across the two safety monitored inputs while the dual safety outputs use forced guided relays to ensure peace of mind in times of need. An automatic restart model is available or manual edge detection restart is also available with an intrinsically safe restart circuit.

The requirements for explosion protection apply in many areas of the industry including chemicals, gases, materials handling and even food processing where powdered ingredients or end products are processed, manufactured or stored.
