Safety relay modules

All equipment versions can be employed in applications up to cat. 4 / PL e according to EN ISO 13849-1 and SIL 3 according to EN 62061 / IEC 61508.

A key advantage of the new PROTECT SRB-E range is that, with each basic version, several dozen existing safety relay modules can be replaced thanks to the multi-functionality of PROTECT SRB-E. Each module can be configured for up to eleven different applications via a simple control element. All conventional safety sensors and electromechanical safety equipment can be monitored.

The reduced number of versions and a clear overview of the eight versions with their relevant functions is said to make it considerably easier for the machine manufacturer to select the right module for its particular application.
