Voltage input AI (U)
Fig. 31: example connection: voltage input
Only use the corresponding AGND for each voltage input.
Do not connect AGNDs from different channels.
AGNDs from different channels must always be connected separately to the plug X1.
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).
