I/O Module Terminal Board Posts
The terminal board has three posts on the left side. The top and bottom posts hold the terminal
board cover in place. The middle post keeps the terminal board wiring in place. If you do not
require it to hold the wiring in place, the middle post can be easily snapped off. (Be careful that you
do not inadvertently snap it off if you need it to keep your wiring in place.)
Installing and Removing Terminal Boards with Holding Screws
Discrete output modules IC693MDL730F (and later) and IC693MDL731F (and later) have a
special terminal board that is equipped with holding screws, shown in the figure below. These
screws prevent the terminal board-to-module connections from deteriorating in applications where
the PLC is subjected to severe vibration .
