Allen-Bradley 1756-OW16I Digital Output Module

The Allen-Bradley 1756-OW16I is a rugged digital output module designed for industrial automation systems requiring precise control of high-current loads. This module delivers reliable switching for devices like solenoids, motor starters, and indicator lights in challenging environments. Its 16 relay outputs with 2A per-channel capacity make it particularly suited for discrete manufacturing and process control applications where durability matters.

This module works particularly well in applications like packaging machinery with frequent actuator control, HVAC systems requiring motor starter coordination, and material handling equipment needing robust output switching. We’ve supported installations in automotive plants using it for conveyor belt control, and in food processing facilities managing solenoid valves for washdown systems.

In our experience, customers appreciate how the 1756-OW16I integrates seamlessly with Rockwell’s Studio 5000 platform while maintaining backward compatibility with existing ControlLogix systems. The built-in LED diagnostics reduce troubleshooting time by 30-40% compared to older module generations. This makes it a popular choice for both new installations and system upgrades.

Our inventory includes related Rockwell Automation products such as the 1756-L71 controllers, 1794-IB16 input modules, and 2711-B6C20 touchscreens. For redundancy applications, we often pair it with 1756-IR612I modules in safety-critical systems.
