Function
The AI8/16-U module has 16 analogue inputs. If signal lines are single-ended (measured against earth, L-),
16 channels are available. To measure differential signals, you will need 2 channels for every signal, i.e. you
can pick up no more than 8 differential signals. Channels can be combined as follows: 0/1, 2/3, 4/5, 6/7, 8/9,
10/11, 12/13 and 14/15.
