Product Specifications
Cold Junctions
Cold junctions have a prewired Pt100 thermocouple on plug openings 1 and 2 for numerically
correcting the thermoelectric voltage. Cold junctions are available in green and blue. Use
green cold junctions for non-intrinsically safe circuits and blue cold junctions for intrinsically
safe circuits.

Coding Pins
Coding pins provide a unique assignment between I/O modules and terminal blocks or the
associated field devices. To do this, the coding pins are pushed into the grooves provided in
the front sockets of the I/O modules. This prevents terminal blocks from being accidentally
plugged into another I/O module.
