Analog Output Option Board
Section 10-6
Wiring for Analog Outputs
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) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(3) When there is noise in the power supply line, install a noise filter on the
input section and the power supply.
(4) When external power is supplied, or when the power is interrupted, there
may be a pulse status analog output of up to 1 ms. If this status is a prob-
lem, take the following measures.
• Turn ON the power to the CP1L-EL/EM CPU Unit, check the operation
status, and then turn ON the power at the load.
• Turn OFF the power to the load and then turn OFF the power to the
CP1L-EL/EM CPU Unit.
!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.
