Safety Monitors AS-Interface

Ask a question about this product

The "Basic" safety monitor and its expanded version are the core elements of ASIsafe. They monitor data transferred via AS-Interface (master call, response from the safe slave). The safety monitor brings the system into a safe condition if the safety circuit is interrupted or safety-related sensors are faulted. It therefore acts as a bus-based safety relay. The standard infrastructure of the AS-i network can continue to be used without restrictions.

The PC-based ASIMON software is used to configure the safety monitor. The response to various input signals can be defined via its graphic user interface.
