Figure 7-50 Terminal assignment for the digital inputs
Power supply for digital inputs (X111, X222, X333: Pin 2):
The internal power supply (P24OUT) is taken from the general power supply of module X1,
pin 2 (P24). Alternatively, an external power supply can be connected if the load at the digital
outputs becomes too high.
