Allen-Bradley 1771-OAN PLC-5 Digital AC Output Module

Description

The Allen-Bradley 1771-OAN PLC-5 Digital AC Output Module is a fused digital output unit belonging to the 1771 series, designed for industrial automation control systems. As a single-slot module, it installs into a 1771 I/O chassis, integrating with other I/O components to build comprehensive automation systems that control external industrial equipment. Key technical specifications include 16 independent AC output channels, each capable of delivering 2A of continuous current, with a total module current rating exceeding 8A. It operates with an input voltage range of 184 to 250V AC, 47 to 63Hz, making it compatible with standard industrial AC power supplies. Each output supports a surge current of 25A for 100ms, repeatable once per second, matching the surge rating of the entire module. For low-current loads at 220V AC (60Hz), each output requires a minimum holding current of 10mA to remain active, with a maximum voltage drop of 1.5V at full 2A load. Its fused output design provides built-in protection for connected devices, while its modular form factor enables flexible system configuration and easy integration into PLC-5 based automation setups for manufacturing, processing, and other industrial control applications.
