Isolator Monitor Module

The loop monitor module can monitor up to three speaker line loops on break and short circuit when the speaker lines are equipped with the isolators VM-300IS. In case of a failure, it will be reported to the system and can be indicated. Each speaker line can be equipped with up to 60 isolators VM-300IS.


The loop monitor module consists of pre-assembled PCBs for an easy DIN rail mounting (snap-in clamps).
