The difference between analog signals and binary signals or switching contacts is that only one concrete signal status is transmitted. Surge voltages can, however, interfere with the transmission of statuses, which in turn results in system errors. The right surge protection protects your signal transmission and ensures that your system keeps running.

Switching states and signal contacts are typical signals that are recorded with the binary inputs on controllers. The controllers also switch actuators such as solenoid valves. Use suitable surge protection to protect the sensitive inputs and outputs on 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.
