Allen-Bradley 1756-OA16 16 Point DC Output Module

The Allen-Bradley 1756‑OA16 is a 16‑point ControlLogix output module that switches AC loads from a standard 1756 backplane, designed to integrate with Rockwell Automation’s ControlLogix chassis and programming environments such as Studio 5000 and RSLogix 5000. Each of the 16 outputs is rated up to 0.5 A per point at a voltage range of 74 to 265 VAC, enabling direct control of common AC devices such as relays, contactors, lighting, and other low‑to‑mid‑power loads in both North American and international configurations. The module uses a 20‑pin interface to connect to the I/O bus and to the external field wiring, allowing deterministic On/Off switching of connected devices as part of a cohesive automation system. Common applications include conveyors, packaging lines, automated presses, and other manufacturing cells where centralized PLC control of AC outputs is required, offering a compact, single‑card solution for expanding output capacity without introducing separate controllers. As part of the 1756 family, the OA16 can be combined with other I/O and control modules to scale an automation environment and to support synchronized control across multiple devices in an integrated control system.
