1. INTRODUCTION
The FX
-4AD-PT analog block amplifies the input from four platinum temperature sensors (Pt 100, 3
2N
wire, 100 Ω) and converts the data into 12 bit reading's stored in the main unit. Both Centigrade (°C)
and Fahrenheit (°F) can be read. Reading resolution is 0.2°C to 0.3°C / 0.36°F to 0.54°F.
The FX
-4AD-PT can connected to the FX

Controllers (PLC).
All data transfers and parameter setups are adjusted via software control of the FX
of the TO/FROM applied instructions in the PLC.
The FX
-4AD-PT occupies 8 I/O points on the PLC expansion bus. The 8 I/O points can be allocated
2N
from either inputs or outputs. The FX
-4AD-PT draws 30mA from the 5V rail of the main unit or
2N
powered extension unit.

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.
