1. INTRODUCTION

• The FX

-4AD-TC analog block amplifies the signal from four thermocouple sensors (Type K or J) and

converts the data into 16 bit reading’s stored in the main unit. Both Centigrade (

C) and Fahrenheit

(

F) can be read.

Reading resolution is 0.4

C/0.72

F of Type K and 0.3

C/0.54

F of Type J.

• The FX

series

Programmable Controllers (PLC).

• All data transfers and parameter settings are adjusted via software control of the FX

-4AD-TC; by

use of the TO/FROM applied instructions in the PLC.

• The FX

-4AD-TC occupies 8 I/O points on the PLC expansion bus. The 8 I/O points can be allocated

from either inputs or outputs. The FX

-4AD-TC draws 30mA from the 5V rail of the main unit or

powered extension unit.

• Thermocouples with the following specifications can be used: Type K (JIS C 1602-1995)

Type J (JIS C 1602-1995)

PLCs. Other

special units of blocks that use FROM/TO commands, 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. For the connection with PLCs, refer to the respective PLC manual.

4. WIRING

4.1 Wiring

*1:The compensating cables that can be used for

connecting with the thermocouple are the following.

Type K: KX-G, KX-GS, KX-H, KX-HS,WX-G,WX-H,VX-G

Type J: JX-G, JX-H

For every 10

Ω

of line resistance, the compensating

cable will indicate a temperature 0.12

C higher than

actual.

Check the line resistance before using.

Long compensating cables are more prone to noise

interference, therefore a short (less than 100m)

compensating cable is recommended.

Unused channels should have a wire link connected

between the + and - terminals to prevent an errors being

detected on that channel.

*2:If there is excessive electrical noise, connect the SLD

terminal to the ground terminal on the unit.

*3: Connect the ground terminals of the FX

-4AD-TC unit and the main unit. Use grounding on the main

unit.

*4: The 24V DC built-in supply of the PLC may be used as the power supply.

4.2 Using crimp terminations

• Use crimp terminals as indicated on the left.

• The tightening torque must be 0.5 and 0.8 N

⋅

m. Do not tighten

terminal screws exceeding the specified torque. Failure to do so may

cause equipment failures or malfunctions.

• Wire only to the module terminals discussed in this manual. Leave all

others vacant.

Note: Earth-tipped thermocouples are not suitable for use with this unit.

5.4 Installation location

This unit measures temperature according to the temperature difference between the temperature

measurement part (themocouple) and the terminal block. If this unit is installed at a place where the

temperature of the terminal block varies rapidly, a measuring error may occur. For this reason, the unit

should be installed at a place free from excessive temperature variation.

6. ALLOCATION OF BUFFER MEMORIES (BFM)

6.1 Buffer memories

The FX

-4AD-TC communicates

with the PLC via buffer memories.

BFMs #21 to #27 and #31 are

reserved.

All non reserved BFMs can be read

by the PLC using the FROM

instruction.

BFMs (buffer memories) marked

with an “*” can be written to, the

special function block using the TO

instruction.

Item

Centigrade (

C) Fahrenheit (

Both

C and

F are available by reading the appropriate buffer memory (BFM).
