3.1 Connection with PLC
The FX
-4AD-PT unit can be connected to the PLCs as follows. Restrictions apply to the maximum
2N
number of connectable units, depending on the DC24V/DC5V Power Supply capacities and the Main Unit/
Special Function Unit types. For details, refer to the respective PLC manual.

No.1
The cable of the Pt 100 sensor or a twisted shielded
cable should be used for the analog input cable. This
analog input cable should be wired separately from
power lines or any other lines which may induce noise.
The three wire method improves the accuracy of the
sensors by compensating voltage drops.
If there is electrical noise, connect the FG (frame
ground) terminal with the ground terminal. (In CH1,
5V
there is no FG terminal. Use FG terminal of other
channels.)
+15V
Connect the ground terminal on the FX
-15V
with the grounded terminal on the main unit. Use
grounding on the main unit, if grounding is possible.
Either an external or the 24V built-in supply in the PLC
may be used.
For additional data regarding EMC considerations
please see section 10.
