Electromagnetic compatibility

Definition
Electromagnetic compatibility refers to the capability and reliability of electrical equipment in
performing its function in an electromagnetic environment without causing interference in the
same environment.
The ET 200S distributed I/O system meets all EMC legislation requirements for the
European market. As a prerequisite the ET 200S distributed I/O system must satisfy the
specifications and guidelines concerning electrical installation.
Pulse-shaped Interference
The following table shows the electromagnetic compatibility of the ET 200S distributed I/O
system when compared with pulse-shaped interference.
Electrostatic discharge according
to IEC 61000-4-2
Burst pulse (fast transients)
complying with IEC 61000-4-4
High-energy single pulse (surge) according to IEC 61000-4-5
Only with lightning protection elements (see the DP master manual and

Sinusoidal Interference
The following table shows the electromagnetic compatibility of the ET 200S Distributed I/O
System when confronted with sinusoidal interference.
● HF radiation according to IEC 61000-4-3
● HF coupling according to IEC 61000-4-6
