Monitoring surge protection for signal interfaces

20 November 2023

Surge protective devices from Phoenix Contact are able to protect signal lines from surge voltages caused by switching operations or lightning strikes.

The TERMITRAB product family enable surge protection without being space hungry. Often, the protective components are installed in several control cabinets or in the field which can make it difficult to gain a permanent visual check of the protective devices on site. 

The TERMITRAB range, however, enable users to visually monitor up to 50 devices. The devices record the status of all the protective modules and, in the event of a fault, output an alarm to a central signaling contact.
