If both inputs and outputs are operated on a digital inputs/outputs group, it is recommended
that both the inputs and the outputs are fed with the same 24 VDC supply:
Figure 6-2 Inputs and outputs on the same supply
If the inputs and outputs supplied separately with power, the input current can exceed the
permissible value of 15 mA according to EN61131-2. This may possibly cause the signal
source to be overloaded:
