VI-6777

The VI-6777 Isolate Interface is the module that monitors the short circuit fault at the loop ,It has dual side isolation ,if it detects the short circuit on loop it will isolate that side to ensure loop communication signal will not be affected or interrupt by short-circuit fault.
The advantage of a dual side isolation module can indicate the location of a short circuit through LED indicator ,facilitating on-site troubleshooting.
