Terminal Block Quick Connect Components for 32-Point Modules
The 32-point modules do not require a new faceplate since they are equipped with a dual-connector
faceplate as a standard feature. Since each module has two 24-pin connectors, they each require
two cables and two terminal blocks. Also, since the modules' two connectors are oriented
differently (see example in figure below), the two cables are different. One is called a "right side"
cable and the other, a "left side" cable.

These terminal blocks will not work with the 32-point I/O modules that have 50-pin
connectors.
