Temperature input/output (i/o) module with integrated thermistor for cold junction compensation

An I/O module base comprising:

• a body adapted to selectively receive an associated removable terminal block;
• a printed circuit board assembly including I/O circuitry connected to the body;
• a plurality of contact pair constituents connected to said body and each electrically connected to said I/O circuitry of the printed circuit board assembly, wherein each of said plurality of contact pair constituents is configured to mate electrically with an associated contact pair constituent connected to the associated removable terminal block;
• a first CJC sensor connected to said printed circuit board assembly and operatively connected to said I/O circuitry, said first CJC sensor thermally associated with and adapted to sense a temperature of at least a first one of said contact pair constituents of said body.

An I/O module comprising:

• an I/O module base comprising a printed circuit board including I/O circuitry;
• a removable terminal block removably connected to and selectively separable from the I/O module base, said removable terminal block comprising a plurality field wiring terminals that are operatively connected to said I/O circuitry when said removable terminal block is connected to said I/O module base;
• a first CJC sensor physically connected to said I/O module base and operatively connected to said I/O circuitry, said first CJC sensor adapted to sense a first temperature associated with at least a first one of said field wiring terminals of said removable terminal block, wherein said first CJC sensor is physically connected to said I/O module base both:
• (i) when said removable terminal block is physically connected to said I/O module base;
• and (ii) when said removable terminal block is physically separated from said I/O module base.
