Allen-Bradley 1746-OB8 SLC 500 DC Output Module | Original Spare Parts

Allen-Bradley 1746-OB8 — SLC 500 DC Output Module (8-Point 24VDC Source) | Original Spare Parts

As a procurement manager sourcing critical components for industrial automation infrastructure, you need parts that perform without compromise. The Allen-Bradley 1746-OB8 is a factory-sealed, 100% Brand New and Factory Sealed DC output module purpose-built for Rockwell Automation’s SLC 500 PLC System. Delivering eight independent 24VDC sourcing output channels, this Original New control module provides the switching precision and reliability demanded by continuous-process and discrete manufacturing environments alike. Every unit of the 1746-OB8 shipped from our inventory is verified against Allen-Bradley’s original factory specifications — no refurbished, no counterfeit, no compromise.

Industrial facilities operating Oil & Gas pipelines, Power Plants, Water Treatment systems, and Automotive Assembly lines depend on the SLC 500 platform for mission-critical control. When a DC output module fails, every minute of downtime translates to measurable production loss. The 1746-OB8 addresses this pain point directly: its robust optical isolation architecture and heavy-duty screw terminal blocks are engineered for harsh environments where signal integrity and long service life are non-negotiable. Whether you are maintaining an aging SLC 500 rack or expanding an existing PLC System, this Spare Parts module slots in without reconfiguration.

Backed by a 1-Year Warranty and supported by our global logistics network, sourcing the 1746-OB8 through Industrial Control Hub means fast delivery, full documentation, and expert technical support — from initial inquiry to post-installation commissioning. Contact us today for a competitive quote.

Core Features & Technical Advantages

• 8 Isolated DC Output Channels — Precision sourcing (positive logic) control for solenoids, contactors, and indicator devices
• 24VDC Source Output — 1.0A continuous per point; 2.0A surge (100ms) for inductive load compatibility
• 1500V Optical Isolation — Robust galvanic separation between logic and field circuits eliminates ground loop interference
• Removable Screw Terminal Blocks — Heavy-duty field wiring connectors enable rapid module swap without rewiring
• Individual LED Status Indicators — Real-time per-channel diagnostics accelerate fault isolation and reduce MTTR
• 1ms Typical ON/OFF Response — High-speed switching supports time-sensitive control sequences in automated production lines
• 100% Original and Brand New — Factory sealed, full Allen-Bradley traceability, E-E-A-T compliant sourcing

Technical Specifications & Selection Guide

Selection Guide: Choose the 1746-OB8 when your application requires 24VDC sourcing outputs with positive logic. For sinking (NPN) output requirements, consider the 1746-IB8. For relay (dry contact) outputs, the 1746-OW8 is the appropriate alternative.

Typical Application Scenarios

The 1746-OB8 is deployed across a wide spectrum of industries where the SLC 500 PLC System remains the backbone of Industrial Automation:

• Oil & Gas: Controls pneumatic valve solenoids and shutdown actuators in wellhead and pipeline SCADA systems. Its optical isolation protects the control module from field-side voltage transients common in hazardous-area installations.
• Power Plants: Drives motor starter contactors and annunciator panels in auxiliary systems. The 1.0A continuous rating handles the inrush demands of industrial-grade coils without derating.
• Automotive Assembly: Interfaces with robotic work cell tooling, conveyor drive signals, and part-present indicator towers — applications where 1ms response time is operationally critical.
• Water & Wastewater Treatment: Activates pump motor starters and chemical dosing solenoids in remote lift stations where EOL legacy system support is essential for long-term operational continuity.
• Food & Beverage Packaging: Sequences pneumatic actuators and reject gates on high-speed packaging lines, leveraging the module’s removable terminals for rapid changeover maintenance.
