Inline Modular IO: Supply voltage requirements that differ from the system
specifications
The specifications for Inline system supply voltages are described in "Technical data for
Inline Modular IO" on page 11-1. However, some terminals have specific requirements.
Therefore, always refer to the corresponding data sheet.
This section provides information about the various possible requirements within an Inline
system.
Two options are available when using terminals, which have special requirements regarding
the power supply:

WARNING: Dangerous contact voltage
Only use power supply units that ensure safe isolation between the primary and
secondary circuits according to EN 50178.
For additional power supply requirements, please refer to the documentation for your bus
coupler and the power terminals.
If you are using Inline in a system with other product ranges, also observe the technical
data for these product ranges. Please refer to the corresponding documentation for this
technical data.
Observe the specific parameters for the power supply in the entire system.
Observe the specific parameters in the main circuit where the terminals are located.
