6.2 Electromagnetic
compatibility
Definition
Electromagnetic compatibility is the capability of an electrical system to function
satisfactorily in its electromagnetic environment without disturbing its surroundings.
The ET 200R distributed I/O device also fulfills, among others, the requirements of
the EMC law of the European domestic market.
Prerequisite for this: The cabling must be made in accordance with the specifica-
tions and guidelines of electrical setup.
Pulse-shaped interference
The following table shows the electromagnetic compatibility of the ET 200R distri-
buted I/O device in the presence of pulse-shaped interference.
Pulse-Shaped Interference
