Safety Monitor

The Safety Monitor enables safe transmission and processing of safety relevant data from safety input modules and safe shut-off of safety output modules remotely over ASi right where the potentially hazardous motion takes place. And always PLe compliant.

Bihl+Wiedemann offers the Safety Monitor for ASi Safety at Work as a stand-alone device for expanding existing ASi circuits with safety modules. For new systems we can provide our ASi-3 resp. ASi-5/ASi-3 gateways with integrated Safety Monitor and interfaces for the most commonly used automation systems using the most efficient method for safely constructing 1 or 2 ASi circuits at the same time. Even large applications with up to 1922 safety I/Os can be implemented with these devices using our “Safe Link over Ethernet” technology by connecting multiple gateways safely over Ethernet/Profinet.

For small applications with three or more safe signals you should consider our Safety Basic Monitor, a compact safety controller without gateway but with configurable status outputs. The module allows for universal expansion and is also ideal as a head station for special safety applications.
