9.2 Electromagnetic compatibility
Definition
Electromagnetic compatibility is the ability of an electrical apparatus to function in a
satisfactory manner in its electromagnetic environment without affecting this environment.
The ET 200AL IO-Link I/O modules fulfill the requirements of the EMC law of the European
Single Market. The prerequisite for this is that the ET 200AL IO-Link I/O modules comply with
the requirements and guidelines regarding the electrical configuration.
Pulse-shaped disturbance variables
The following table shows the electromagnetic compatibility of the ET 200AL IO-Link I/O
modules with respect to pulse-shaped disturbance variables.
