1734-OB8E Allen Bradley Point I/O Digital Output Module
The Allen Bradley 1734-OB8E is a compact, high-performance 8-channel digital output module from the Point I/O™ series, designed for distributed I/O architectures in industrial automation. As a source-type output module, it provides 24V DC outputs to drive external devices like relays, solenoids, indicators, and small motors. Built for reliability, it includes electronic protection, status diagnostics, and seamless integration with Rockwell Automation controllers.
Key Features
8-Channel Source Output: Delivers 24V DC power to loads, with each channel supporting 1A continuous current (2A total module capacity).
Wide Voltage Range: Operates at 10-28.8V DC, accommodating fluctuating power conditions.
Electronic Protection: Guards against overcurrent, short circuits, and overvoltage to prevent module damage.
Fast Response: Output signal delay is ≤0.1ms for rapid control actions.
Diagnostic Capabilities: 8 yellow output status LEDs, 8 red fault indicators, and 2 green/red module/network LEDs for real-time monitoring.
Compact Design: Slim profile (56.0 × 12.0 × 75.5mm) saves panel space and supports DIN rail mounting.
Hot-Swap Support: Enables module replacement without system shutdown, minimizing downtime.
Applications
The 1734-OB8E is ideal for:
Discrete Control: Driving relays, contactors, and solenoids in machinery.
Indicator Systems: Powering status lights in control panels.
Small Motor Control: Operating low-power motors in conveyors or valves.
Distributed I/O: Expanding I/O capacity in modular automation systems.
