The Allen-Bradley 1771-ALX is an Extended local I/O adapter module.

An I/O adapter module in a chassis with I/O modules interfaces the I/O modules with the I/O link for communication with a scanner port for a processor at another location. I/O adapter modules for 1771 I/O are available for ControlNet, Universal Remote I/O, and Extended Local I/O links.

For 1771 I/O to be controlled by a processor other than one in the same chassis with the I/O modules, an I/O adapter module must be placed in left-most slot of the chassis containing the I/O modules.
