Integrated exchangeable microfuse Monitoring of the fuse Potential for routing as needed The potential distributor module provides 12x ground (from the internal I/O supply) on the terminal connections and opens up additional wiring possibilities for actuators and sensors.
The module is equipped with a replaceable microfuse between the GND potential on the terminal block and the X20 system I/O supply.
The function of the fuse is monitored.
