The new Linetrab surge protection devices from Phoenix Contact provide effective surge protection for control systems and process plants and help to prevent costly downtimes.
The narrow surge arrestors protect up to four signal wires with diameters of 6.2 mm. When connected in the appropriate manner, it is possible to provide surge protection for four-cable measurements using just a single module.
Normal mode surge protection between the signal wires can be extended to almost any I/O count across multiple modules using a t-bus adapter for mounting rails. This can provide effective protection for interfaces with more than four signals (e.g., for six line measurements). Since the surge-resistant PE snap-in foot
establishes a local equipotential bond already during assembly, this saves both time and money.
Using the PLC Interface system cabling, the surge protectors can be quickly and easily connected to signal converters or isolators, like the Mini Analog isolating amplifiers from Phoenix Contact or to any conventional PLC.
