Removable PCB terminal block cold junction compensation

An input module comprising:

• a terminal block including a housing defining a plurality of terminals and at least one opening associated with each terminal of the plurality of terminals, the at least one opening being configured to receive an external wire of an external thermocouple;
• an electrical connector assembly received by at least one terminal of the plurality of terminals of the terminal block, the electrical connector assembly including an internal thermocouple and a pivot member, the internal thermocouple having a first leg and a second leg formed of different materials, the first leg and the second leg being coupled together at a first end of the internal thermocouple and spaced apart to define a jaw connector at a second end of the internal thermocouple, and the pivot member being pivotable relative to the housing to couple the external wire to the first end;
• and
• a printed circuit board coupled to the electrical connector assembly via the jaw connector, the printed circuit board including a processing circuit configured to perform cold junction compensation for a temperature associated with the external wire based on a temperature of the printed circuit board and a temperature or a voltage of the internal thermocouple.
