NOTICE
230.x.x models
The digital inputs are divided into two groups, each of four inputs. All inputs must
be operated on the same phase. Different phases are not allowed.
Fig. 3.3 Connection of 3-wire sensors with PNP transistor outputs to digital inputs (24.x.x
only)
For 24.x.x models, it is permissible to connect sensors with switch contacts and transistor
outputs to digital inputs within the same input group.
If the galvanic isolation between inputs groups is not required, a common power supply,
including the integrated 24 VDC voltage source, can be used for both groups.

Different sensors can be connected within a group. For example, AI1 can be configured as
digital and AI2 as analog 4-20 mA.
