Current input AI (I)
Fig. 18: Example connection: current input
Only use the corresponding AGND for each power input.
Do not connect AGNDs from different channels.
Only use one channel per function: either AI (U) or AI (I).
Do not connect to the common GND. The required connections can already be found on the circuit
board.
Cables to the analogue sensors/encoders should be connected as directly as possible (avoid the use of
terminals and terminal blocks).
