Terminal Layouts 

 

 

 
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 FG terminal to the ground terminal on the unit. 

3)

 

Connect the ground terminals of the LX3V-4TC module and the PLC. Use grounding on the PLC. 

4)

 

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

Installation notes and usage

Specification 

 

Be  sure  to  use  the  crimp-style  terminals  that  satisfy  the 

dimensional requirements shows in the left figure. 

 

Apply 0.5 to 0.8 N.m (5 to 8 kgf.cm) torque to tighten the 

terminals to prevent abnormal operation. 

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  10Ω  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.
