Electromagnetic Compatibility

Introduction
This section contains information on the interference immunity of the fail-safe I/O
module and information on radio interference suppression.
Definition of EMC
Electromagnetic compatibility is the ability of an electrical device to function in its
electromagnetic environment in a satisfactory manner without affecting this
environment.
The fail-safe ET 200eco I/O module also satisfies the requirements of the EMC
directive of the European Economic Area. This is possible only when the ET 200S
distributed I/O station complies with the specifications and guidelines for electrical
assembly.
Pulse-Shaped Interference
The following table shows the electromagnetic compatibility of the fail-safe I/O
module with regard to pulse-shaped interference.
Pulse-Shaped Interference
Electrostatic discharge in
accordance with
IEC 61000-4-2
(DIN VDE 0843 Part 2)
Burst pulse (rapid transient
interference) in accordance
with IEC 61000-4-4
(DIN VDE 0843 Part 4)
Surge in accordance with IEC 61000-4-5 (DIN VDE 0839 Part 10)
Degrees of severity 2 and 3 require an external protective circuit
