Activate all outputs when testing the current consumption!
If the electrical consumption of a power supply point for the 24 V system
supply exceeds 500 mA, then the cause may be an improperly
dimensioned node or a defect.
During the test, you must activate all outputs.

Field Supply
3.4.4.1 Connection
Sensors and actuators can be directly connected to the relevant channel of the
I/O module in 1, 2, 3 or 4 conductor connection technology. The I/O module
supplies power to the sensors and actuators. The input and output drivers of
some I/O modules require the field side supply voltage.
The power supply modules provide field side power (24 VDC). In this case it is a
passive power supply without protection equipment. Power supply modules are
available for different potentials, e.g. 24 VDC, 230 VAC or others.
Power supply modules with or without diagnostic capability are available for the
power supply of other field potentials (e.g. 24 VDC, 0 VAC/DC … 230 VAC/DC,
120 VAC, 230 VAC). The power supply modules can also be used to set up
various potential groups. The connections are connected in pairs to a power
contact.
