Allen-Bradley 1734-OB8 8-Point Digital Output Module

The Allen-Bradley 1734-OB8 is an 8-channel digital output module for the POINT I/O system that provides eight 24 V DC sourcing outputs. Designed to mount in a POINT I/O rack and communicate with a compatible Allen-Bradley controller over the POINT Bus, it is intended for switching discrete field devices such as relays, contactors, and indicator lamps from a 24 V DC supply. The module delivers eight independently operable sourcing outputs, enabling compact, high-density control of multiple loads in automation cabinets. Technical characteristics include a 24 V DC output voltage, a POINTBus power draw of about 75 mA, and a total module power dissipation of around 2 W. The electronics are described as electronically protected, helping to guard against common faults on the I/O bus. As part of Rockwell Automation’s POINT I/O family, the 1734-OB8 is compatible with controllers that support POINT I/O (such as ControlLogix and CompactLogix platforms) and is suitable for scalable, modular automation architectures where eight discrete 24 V DC loads need to be controlled from a single I/O module.
