Allen-Bradley 1762-OB16 16-Point DC Output Module

Allen-Bradley 1762-OB16 is a 16-point 24 V DC digital output module designed for MicroLogix control systems. This DIN-rail mounted expansion I/O module provides 16 sourcing (PNP) transistor outputs to switch 24 V DC field devices, making it suitable for controlling solenoids, relays, contactors, and indicator lights in industrial automation setups. It is commonly installed in MicroLogix 1100 and 1200 expansion assemblies within control panels, packaging equipment, material handling systems, and other small automation machinery that require reliable discrete output control. The module supports 24 V DC loads and expands I/O for MicroLogix 1100/1200 controllers, enabling straightforward integration of DC-controlled devices into PLC-based systems. As a common replacement, it is compatible with Allen-Bradley 1762-OW16 and 1769-OB16 blocks, and is often considered alongside alternatives such as Siemens 6ES7222-1HF32-0XB0 for similar 24 V DC output applications.
