Plug-in Surge Protection for Process I/O

Multistage protection is included in each plug-in module, which may be easily changed whilst the DIN rail mount base module containing the wiring terminals remains intact. As well as models suitable for most signalling schemes a series surge protector for 12V and 24V power circuits and a range of interposing relays are available.

The new Novaris SL plug-in protector is only 7mm wide. It maximises space within marshalling cubicles and allows for easy retrofit. It can simply replace two 4mm terminals with room to spare. The plug-in surge protection modules allow for easy, quick and cost effective replacement. The failsafe design means identification of a module failure is straightforward, as the circuit will open an isolate the line.
