The latest addition to Schmersal's line of safety controllers: The PROTECT SRB-E series. They are multifunctional, configurable, electronic safety controllers.
 
Each module in the series can be adjusted to one of up to 11 preset configurations which include selecting the type of reset, activating or deactivating cross-wire monitoring, and selecting the monitored contact configuration all via a rotary dial on the front. Once changed to the desired setting, the dials are protected from further adjustment by a transparent front cover which can be easily secured.

The series variants include:

The PROTECT SRB-E series is distinguished by very short response times and detailed diagnostic and status reports via LED displays. The housings are compact and feature removable terminal blocks with customizable coding strips.

The drastically reduced number of versions and a clear overview of their relevant functions make it considerably easier for a machine manufacturer to select a module from this series which is right for their particular application. All conventional safety sensors and electromechanical safety equipment can be monitored. The safety relay modules of the PROTECT SRB-E series can be used in applications up to Category 4, PLe in accordance with ISO 13849 and SIL 3 in accordance to IEC 61508.
