I/O terminals
The figure below shows the I/O terminals. Tightening torque is 0.4 N·m / 3.5 lbf·in.
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).
