The PCD3.C200 module carriers provide the following internal supply currents for
the plugged or connected modules:
Type
+ 5V
V +
The load capacity of the + V bus depends on the
load of the 5 V bus as follows (the more precisely
the 24 VDC are maintained, the higher the
possible load)

When planning PCD3 systems, it must be checked whether the two internal power
supplies are not overloaded. This control is especially important when using
analog, counting, and positioning and other special modules, as some of them
consume a relatively large amount of power.
It is recommended that you use the PG5 Device Configurator
