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 , FX , FX
2N 0N 1N
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.

However the following limitation exists when the undermentioned special function blocks are
connected.
FX : Main unit and powered extension units of 32 I/O points or less. Current consumption

be connected regardless of the system I/O.
2) Each block occupies 8 I/O points (The 8 points can be allocated from either inputs or outputs).
3) FX -4AD-PT consumes 30mA from the 5V DC bus.
2N
The total 5V consumption of all special function blocks connected to an FX
FX extension unit must not exceed the 5V source capacity of the system.

3.2 Special function block numbers
Other special units of blocks that use FROM/TO instructions, such as analog input blocks, analog output
blocks and high-speed counter blocks, can be directly connected to the main unit of the PLC or to the right
side of other extension blocks or units.
