The 1771-IFE series C module can be used with any 1771 I/O
chassis. Communication between the discrete analog module and the
processor is bidirectional; the processor block-transfers output data
through the output image table to the module and block-transfers
input data from the module through the input image table. The
module also requires an area in the data table to store the read block
transfer data and write block transfer data. I/O image table use is an
important factor in module placement and addressing selection.
Compatibility and data table use is listed below.

You can place your input module in any I/O module slot of the I/O
chassis. You can put two input modules in the same module group.
You can put an input and an output module in the same module
group.
Do not put the module in the same module group as a discrete high
density module. Avoid placing analog input modules close to ac
modules or high voltage dc modules.
Do not use this module with a cat. no. 1771-AL PLC-2/20, 2/30
