Designing the System Supply

Designing the system supply requires knowledge of the entire system-side current consumption of the installed I/O modules.

An additional system power supply must be used if:

• The total system-side power consumption exceeds the maximum permissible total current of the system supply

Do not exceed the maximum total current for I/O modules via data contacts! The data contacts for internal system supply can be damaged and the permissible operating temperature can be exceeded by higher values.

You can find product-specific information on “Total Current for System Supply” and “Current Consumption of System Supply (5 V)” in the technical data of the corresponding & Product Manual.

For fast, effortless supply design, use the WAGO Configurator Smart Designer.
