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.
