Analog I/O Units
Section 7-4
Terminal Arrangements
Note
For current inputs, short V IN0 to I IN0 and V IN1 to I IN1.
Wiring for Analog Inputs
Wiring for Analog Outputs
Note
(1) Use shielded twisted-pair cables, but do not connect the shield.
(2) When an input is not being used, short the + and
−
terminals.
(3) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(4) When there is noise in the power supply line, install a noise filter on the
input section and the power supply terminals.
