5.3.6. Example connections of analogue inputs and outputs
Voltage input AI (U)
Fig. 17: Example connection: voltage input
Only use the corresponding AGND for each voltage 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).
