Schmersal is proud to introduce the PROTECT SRB-E series, a range of multifunctional, configurable, electronic safety controllers. The series features safe PNP outputs and can be used to monitor most safeguarding switches such as electromechanical switches, safety light curtains, electronic safety sensors, and coded-magnet sensors. Models are available with input expansion up to Cat.4/PLe, monitoring of two independent safety functions, and monitoring of two-hand controls.
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 dial is protected from further adjustment by a transparent front cover which can be secured.
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. All of 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.
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.
