Recommendation
A stable power supply cannot always be assumed. Therefore, you should use
regulated power supplies to ensure the quality of the supply voltage.
The supply capacity of the fieldbus coupler/controller or the internal system
supply module can be taken from the technical data of the components.

Table 19: Alignment

Internal current consumption
Total current for I/O modules
See current catalog, manuals, Internet

Example:
Calculating the current consumption on an Example Coupler:
Internal current consumption
Residual current for bus modules
Sum I
(5 V) total
The internal current consumption is indicated in the technical data for each bus
terminal. In order to determine the total requirement, add together the values of
all I/O modules in the node.
Please note the aggregate current for I/O modules. It may be necessary to
supply potential!
When the sum of the internal current consumption for the I/O modules exceeds
their aggregate current, you must use a supply module with bus power supply.
Install it before the position where the permissible aggregate current would be
exceeded.
