The Allen Bradley 1771-OAD Series A is an AC output module from the PLC-5 1771 I/O family, designed for use in Allen Bradley 1771 chassis based programmable controller systems. This module provides discrete AC output control for industrial automation applications including machine control, conveyor systems, batch processing, and general factory automation where 120/240V AC field devices require switching from a PLC platform.
Identified by part number 1771-OAD with Series A revision, this module connects to standard 1771 I/O chassis and communicates with PLC-2, PLC-3, and PLC-5 processors through the 1771 backplane. The module switches AC loads such as solenoids, motor starters, contactors, indicator lamps, and small AC motors. Field wiring connects through a removable terminal block on the front of the module, supporting straightforward installation and replacement without rewiring.
The unit shown carries Schneider Electric ReMan Industrial Repair Services documentation referencing original equipment from Alton Steel of Alton, IL. Labels include ReMan Electronics tag 000100563 and Schneider Electric tag 101013039. Buyers searching for legacy Allen Bradley PLC-5 spares, drop in replacements for 1771 series racks, or obsolete I/O module backups for existing installations will recognize this part number. The 1771 platform remains in service in many heavy industry, steel mill, automotive, and process plant installations where full system replacement is not practical, making 1771-OAD modules a continuing source of demand in the industrial surplus market.
