Note
In the circuit example, the power for the digital inputs (terminals -X122 and -X132) is
supplied from the internal 24 V supply of the Control Unit (terminal -X124).
The two groups of digital inputs (optocoupler inputs) each have a common reference
potential (ground reference M1 or M2). To close the circuit when the internal 24 V supply is
used, the ground references M1/M2 are connected to internal ground M.
If power is not supplied from the internal 24 V supply (terminal -X124), the jumper between
grounds 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.
The rapid inputs can be used as probe inputs or as inputs for the external zero mark.
