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 loop 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 loop isolators VM-300IS.


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