Compensação de temperatura no V130

Recommended Posts

  • MVP 2023

Hi, i do not know V130 model present on foto.

Inside the V130-33-TA24 Unitronics PLC contains an MCP9801 chip for thermal compensation of the thermocouple cold junction.

It is located directly next to the TC connector on the PLC I / O board - on the back of the board.


Therefore, I think that all those PLCs that support thermocouples have similar compensation.

On the pages 3-4


you can see TC input parameters and info about automatic cold junction compensation.
