Electrical isolation
Electrical relationships
With the ET 200SP distributed I/O system, there is electrical isolation between:
● The load circuits/process and all other circuit components of the ET 200SP distributed I/O
system.
● The communication interfaces of the CPU (PROFINET) or of the interface module
(PROFINET/PROFIBUS) and all other circuit components.
The figures below show the electrical relationships of the ET 200SP distributed I/O system
with the CPU and the interface module. Only the most important components are
represented in the figures.
