Description
Product Compatibility
The 1771-IFF series A 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 are listed below.

- B = Compatible with 1771-A1B, -A2B, -A3B, -A3B1, -A4B
- Y = Compatible without restriction.
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 catalog number 1771-AL PLC-2/20, 2/30 Local Adapter.
