Voltage and current selection for analog inputs
Switch S1 selects voltage (0 [2]...10 V / -10...10 V) or current (0 [4]...20 mA /
-20...20 mA) as the signal types for analog inputs AI1 and AI2. The factory settings
are unipolar voltage for AI1 (0 [2]...10 V) and unipolar current for AI2 (0 [4]...20 mA),
which correspond to the default usage in the application macros. The switch is
located to the left of I/O terminal 9 (see the I/O terminal figure above).
ON
Top position (ON): I (0 [4]...20 mA, default for AI2; or -20...20 mA)

Bottom position (OFF): U (0 [2]...10 V, default for AI1; or -10...10 V)
