Allen Bradley 1756-OA16I ControlLogix AC Digital Output Module

Product Introduction

The Allen-Bradley 1756-OA16I is a ControlLogix AC digital output module designed for industrial control systems that require reliable and isolated switching of AC loads. As part of the ControlLogix I/O family, this module provides stable output performance, predictable response characteristics, and seamless integration within Rockwell Automation control architectures.
It is commonly selected for applications where electrical isolation, high-current AC switching, and consistent output behavior are critical to system operation and safety.

The 1756-OA16I supports standard 120 VAC and 240 VAC control voltages and is capable of handling higher output current per point compared to standard AC output modules. Its isolated output design helps protect the control system from field-side disturbances, making it well suited for complex industrial environments with mixed power and control wiring.

Product Specifications

Applications

• Used for direct control of AC loads such as contactors, solenoid valves, pilot lights, and alarm devices

• Suitable for high-current AC output applications where standard output modules may not provide sufficient capacity

• Applied in process automation systems requiring electrically isolated outputs for improved system protection

• Commonly implemented in manufacturing lines, power distribution panels, and material handling systems

• Ideal for systems that require clear separation between control logic and field power circuits

Advantages

• Higher output current capability allows reliable operation of demanding AC loads without external relays

• Isolated output design reduces the risk of electrical interference and protects the ControlLogix backplane

• Standard voltage compatibility simplifies system design across global installations

• 16-point output density optimizes chassis space and reduces overall system complexity

• Consistent integration with ControlLogix software tools ensures efficient configuration and diagnostics

• Designed for stable operation in electrically noisy industrial environments
