The new Linetrab surge protection devices from Phoenix Contact 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 degree across multiple modules using a bus adapter for mounting rails. This can provide effective protection for interfaces with more than four signals (eg, for six line measurements). The surge-resistant PE snap-in foot establishes a local equipotential bond already during assembly.
Using the system cabling, the surge protectors can be connected to Mini Analog isolating amplifiers from Phoenix Contact or to any conventional controller.
