Specification

The 1756-OA16 is a high-performance AC output module from the Allen-Bradley ControlLogix family, engineered for demanding industrial automation applications requiring reliable switching of 74-132V AC loads. This 16-point module offers individual channel isolation, ensuring signal integrity even in electrically noisy environments like motor control centers and process lines. Designed for seamless integration into any ControlLogix chassis, the 1756-OA16 supports soft-start output to mitigate inrush current stress on connected devices, extending the lifespan of actuators, solenoids, and contactors. With a wide operating temperature range of 0 to 60°C and built-in surge protection, it is ideal for continuous operation in factory floors, refineries, and water treatment plants. The module’s diagnostic LEDs provide instant visual feedback on channel status, while its compact form factor maximizes I/O density in rack-based systems.
