Note
The digital inputs (terminals -X520 and -X530) in the example are powered by the internal
24 V supply of the customer terminal block (terminal -X540).
The two groups of digital inputs (optocoupler inputs) have a common reference potential for
each group (ground reference M1 or M2). To close the circuit when the internal 24 V supply
is used, the ground references M1 / M2 must be connected to internal ground (M).
If power is not supplied from the internal 24 V supply (terminal -X540), the jumper between
ground M1 and M or M2 and M must be removed in order to avoid potential rounding. The
external ground must then be connected to terminals M1 and M2.
X520: 4 digital inputs
