Product list Signals with a common reference potential
Protect signals with a common reference potential against surge voltages from an overall width starting from just 3.5 mm.
When only one specific switching state is being transmitted, we refer to this as digital signals or switching contacts. In cases like these, the signals are routed over a common reference potential. Overvoltages can interfere with the transmission of statuses, which in turn results in system errors. The right surge protection solution protects your signal transmission and ensures that your system keeps running.
Your advantages
- The world’s narrowest surge protection from an overall width of just 3.5 mm
- Versatile use: designs and connection technology adapted to the application
- Easy testing with pluggable surge protective devices
- Space-saving installation with the narrowest protective devices
Signals with common reference potential
Switching states and signal contacts are typical signals that are recorded with the binary inputs of controllers. The controllers also switch actuators such as solenoid valves. Use suitable surge protection to protect the sensitive inputs and outputs of controllers. The individual binary signals are often connected against a common reference potential. Typical arrangements that take into account this common reference potential are provided by so-called 2x1 or 4x1 circuits.
Products for protecting signals with common reference potential
These products provide surge protection for signals with common reference potential.
TERMITRAB complete with an overall width of 3.5 mm
This is the narrowest surge protection available, with an overall width of just 3.5 mm. The different versions securely protect signals with a common reference potential and isolated signals from surge voltages. Both products are available for nominal voltages of up to 24 V DC with Push-in connection technology.

LINETRAB
The LINETRAB product family provides surge protection in an overall width of 6.2 mm. This allows you to protect up to four signal wires for digital or analog interfaces, including in intrinsically safe areas. Multi-conductor temperature measurements can also be performed via an optional DIN rail connector. LINETRAB is available with screw connection technology.
SURGETRAB S-PT
The SURGETRAB surge protective devices can be screwed directly onto field devices such as measuring elements. Product versions for parallel and through wiring are available. Various voltage and circuit versions are available with different connecting threads. SURGETRAB is available for Ex areas with Ex i (intrinsic safety) and Ex d (flameproof enclosure) type of protection.
COMTRAB modular
COMTRAB modular surge protection is available for marshalling systems with LSA-PLUS connection technology. Up to 10 protective plugs can fit into the CTM 10-MAG magazine. The plugs are available in different voltage and circuit versions. The protective plugs are tested with the CHECKMASTER 2.
