The PCD3.T76x head stations 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 accurate the 24 VDC, 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 particularly important when using
analog, counting and positioning modules, as these sometimes have a fairly large
power consumption.
