To use a connector/terminal block converter module

A connector/terminal block converter module for MELSEC-Q series temperature input module can be used with a temperature 
input module. This section shows the examples of external wiring when a connector/terminal block converter module is used.

Thermocouple input module

Use the connector/terminal block converter module for the Q68TD-G-H02(H01). Wire the modules as shown below.

*1 Connect the cold junction compensation resistor (RTD) when With cold junction compensation (0) is set to 'Cold junction compensation 

with/without setting' (Un\G298).

*2 Ground the shields.
*3 The RTD- and RTDG are connected in the connector/terminal block converter module. Therefore the connection of RTD- and RTDG at 

the terminal block is not required.
