5.3 Electrical configuration of the ET 200S
Galvanic isolation
In the ET 200S, isolation exists between:
● The load circuits/process and all other circuit components of the ET 200S
● The PROFIBUS DP interface in the interface module and all other circuit components
● The PROFINET interface in the IM151-3 PN interface module and all other circuit
The figure below shows the voltage ratios for ET 200S with IM151-1. Only the primary
components are shown in the figure.
