The PROTECT SRB-E range safety monitoring modules serve for the secure evaluation of switching signals. The signals can emanate from mechnical position switches, safety switches, solenoid interlocks or magnetic safety sensors on sliding, hinged or removable guard doors. This series consists of safety relay modules which feature integrated multiple functions.

Each module 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 secured.
A major advantage of this new safety controller range is that, since they have integrated multiple functions, each basic version can replace several dozen existing safety relay modules. The drastically reduced number of versions and a clear overview of their relevant functions make it considerably easier to select the right module for each application.
The PROTECT SRB-E series is distinguished by very short response times and detailed diagnostic and status reports via LED displays. They feature removable terminal blocks with customizable coding strips. 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.
