Allen-Bradley 1771-0D16 16-Point DC Output Module

The Allen-Bradley 1771-0D16 is a 16-point DC output module designed for PLC-5 I/O backplanes, delivering sixteen output channels that are controlled by the PLC-5 processor. It installs in a 1771-series I/O chassis and communicates via the standard backplane, enabling direct switching of DC loads such as relays, contactors, solenoids, and other actuators under program control. As part of the 1771 digital I/O family, the 0D16 provides a scalable way to expand a PLC-5 control system without adding separate controllers, supporting common automation tasks in manufacturing lines and equipment. Catalog entries and manufacturer literature identify the 1771-0D16 as a 16-point DC output option within the 1771 module lineup, reflecting its role alongside other 16-point DC output modules for PLC-5 environments.
