You can install your input module in any system that uses
Allen–Bradley programmable controllers with block transfer
capability and the 1771 I/O structure.
Contact your nearest Allen–Bradley office for more information
about your programmable controllers.
This input 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
and write block data. I/O image table use is an important factor in
module placement and addressing selection. The module’s data table
use is listed in the following table.

Yes = Compatible without restriction
No = Restricted to complementary module placement
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
•
an input and an output module in the same module group.
