Analog I/O (XA CPU Units)
Section 5-5
3. Wiring Analog I/O
Wiring Analog Inputs
Wiring Analog Outputs
Note (1) Use 2-conductor shielded twisted-pair cable for the I/O wiring, and do not
connect the shield.
(2) If an input is not being used, connect (short) the input’s + and
−
terminals.
(3) Wire I/O lines apart from power lines (AC power supply lines, three-phase
power lines, etc.).
(4) If noise is received from power supply lines, insert a noise filter in the
power supply input section.
(5) When noise disturbs the analog input/output cable, install the core as
shown below to improve anti-noise performance.
Recommended ferrite core
Ferrite core (data line noise filter): 0443-164151 (manufactured by Nis-
shin Electric Co., Ltd.)
