3-4-4 Input Wiring Example
Note 1. When using current inputs, turn ON the voltage/current switches. Refer to
3-3-4 Voltage/Current Switch for further details.
2. For inputs that are not used, either set to “0: Not used” in the input number
settings (refer to 3-6-1 Input Settings and Conversion Values) or short-cir-
cuit the voltage input terminals (V+) and (V–). If this is not performed and
the inputs are set for the 1 to 5-V or 4 to 20-mA range, the Line Disconnec-
tion Flag will turn ON.
3. Crimp-type terminals must be used for terminal connections, and the
screws must be tightened securely. Use M3 screws and tighten them to a
torque of 0.5 N·m.
4. When connecting the shield of the analog input cables to the Unit’s AG ter-
minals, as shown in the above diagram, use a wire that is 30 cm max. in
length if possible.
!Caution Do not connect anything to N.C. terminals shown in the wiring diagram on
page 93.
Connecting shielded cable to the Unit’s AG terminals can improve noise resis-
tance.
3-4-5 Input Wiring Considerations
When wiring inputs, apply the following points to avoid noise interference and
optimize Analog Input Unit performance.
• Use two-core shielded twisted-pair cables for input connections.
• Route input cables separately from the AC cable, and do not run the Unit’s
cables near a main circuit cable, high voltage cable, or a non-PLC load
cable.
