Modules
The system supply is used for the power supply of the module.
The field side supply voltage of 0 V and 24 V to downstream I/O modules is
derived from adjacent I/O modules or from a supply module. The supply
voltage for the field side is made automatically through the individual I/O
modules by means of power jumper contacts.

Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must be
added.
