Modular I/O Selection Guide
The following table lists the number of input and output words available for each I/O module in the Slot Con-
figuration list.
Tip: Use the Generic Module to map input and output words for modules that are not represented in the list
of available modules. The range of accepted values is shown in the table below.
Consult the Allen-Bradley user manual for the specific I/O module to configure to confirm input and output
requirements. Requirements may be different based on Class 1 or Class 3 operation.
