The thermocouple/mV module comes with 2 cold junction
compensators. These are designed to mount in designated positions
on the temperature terminal base unit (cat. no. 1794-TB3T). Refer to
chapter 2 for installation instructions for the cold junction
compensator assemblies.
In this chapter, you learned about the FLEX I/O system and the
thermocouple module, and how they communicate with
