You can install your module in any system that uses Allen-Bradley
processors that support block transfer and the 1771 I/O structure.
Contact your nearest Allen-Bradley office for more information
about your programmable controllers.
These modules can only be used with 1771-A1B, A2B, A3B, A3B1,
A4B or later 1771 I/O chassis and 1771-AM1, -AM2 chassis.
Communication between the 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. Refer to the table below.
