CONTROL Logic has released the Novaris SL series of plug-in surge protectors, providing protection against induced surges and transients in twisted pair signalling lines. They can be used to protect PLC I/O, PLC signalling interfaces, fire and security systems, telecommunications and telemetry, railway signalling and other industrial monitoring and control equipment.
Multistage protection is included in each plug-in module, which may be changed while the DIN rail mount base module containing the wiring terminals remains intact. A surge protector for 12V and 24V power circuits and a range of interposing relays are available.
The plug-in protector is 7mm wide. It maximises space within marshalling cubicles and allows for easy retrofitting. It can replace two 4mm terminals. 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.
