Check that the max. supply current for the CPU is sufficient; it generally should
be. In extreme cases, switch to PCD3 expansion units.

Estimate consumption from the 24 V supply. Use estimated values from the
section on "Hardware".
These estimated values can be found in section 3.8.5, "Power consumption of
PCD2/PCD3 input/output modules".
Note that in most applications the outputs place the heaviest load on the 24 V sup-
ply. For 16 outputs with a load current of 0.5 A each, the loading will be 8 A with all
outputs connected.
