Inputs and Outputs
I/O modules include input cards, output cards, and their backplanes. Input cards receive
incoming signals through connectors on their backplanes and forward them to crosspoint
cards. The crosspoint cards route the signals, as directed by the control card, to output cards.
The signals are then distributed from the output card through connectors on their backplanes.
For a comprehensive list of I/O modules and corresponding backplanes with part numbers, see
Part Numbers on page 213.
