Analog Output Option Board
Section 10-6
Wiring for Analog Inputs
To prevent noise, 2-core shielded twisted-pair cable should be used. And the
shield can be connected to the FG terminal if necessary.
Note
(1) If necessary, connect the shield to the FG terminal to prevent noise.
(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.
!Caution
When connecting the analog option board to an outside analog device, either
ground the 0 V side of the PLC’s external power supply or do not ground the
PLC’s external power supply at all. Otherwise the PLC’s external power sup-
ply may be shorted depending on the connection methods of the outside ana-
log device. DO NOT ground the 24 V side of the PLC's external power supply,
as shown in the following diagram.
10-6 Analog Output Option Board
Each CP1W-DAB21V Analog Output Option Board provides two analog outputs.
• The analog output signal range is 0 to 10 V (with a resolution 1/4,000).
