Allen-Bradley 1771-0AD Output Module

Allen-Bradley 1771-0AD is a 16-channel AC output module for the PLC-5 1771 I/O system. It provides sixteen discrete outputs that switch 12–120 VAC loads under PLC control and is designed to drive devices such as relays, contactors, and other AC actuators from a PLC-5 program. This module plugs into a 1771-series I/O rack and shares the standard 1771 backplane interface, enabling straightforward expansion of control logic for AC-powered loads within the PLC-5 ecosystem. Common industrial applications include machine control, panel automation, and process lines where AC outputs energize relays or other AC devices, all while integrating with existing PLC-5 I/O infrastructure.
