Allen-Bradley 1734-OB8 Eight Point Digital Output Module

The Allen-Bradley 1734-OB8 Eight Point Digital Output Module provides eight 24 V DC sourcing outputs for discrete control in POINT I/O systems. Designed for DIN-rail mounting in POINT I/O racks, it communicates on the backplane via a POINT I/O adapter to support scalable I/O expansion in control panels, automated production lines, material handling systems, and process control equipment. It is used to switch solenoids, relays, contactors, indicator lights, and other discrete devices with reliable field-level output control. Commonly installed in industrial automation environments, this module supports eight output points with nominal 24 V DC operation and sourcing (PNP) outputs. The part number is 1734-OB8, manufactured by Allen-Bradley (Rockwell Automation) as part of the POINT I/O series. Common replacements include 1734-OB8E and 1734-OV8, reflecting its role in I/O system expansion, panel upgrades, and automation system integration.
