Note 1 The module has four input groups. Each input group has four inputs and one group signal for power supply
of the inputs. The input groups are activated separately, whereby the relevant group signal is set by the control.
Then the switching states of the associated inputs are read in.
Note 2 Function block required
Note 3 To supply the output circuit, an external supplementary supply (AUX POWER) of 20 to 30 V DC is necessary.
The supplementary supply must comply with VDE 0106 (PELV), safety class III.
