Allen-Bradley 1771-OC DC Output Module — Industrial-Grade Original Spare Parts

As a procurement manager sourcing critical components for continuous production lines, you need parts that ship fast, perform flawlessly, and come with verified authenticity. The Allen-Bradley 1771-OC is a 16-point isolated DC output module purpose-built for Allen-Bradley PLC-5 control systems, delivering 10-30V DC switching capability with 2A per-point current capacity. Every unit we supply is 100% Brand New and Factory Sealed, sourced directly from authorized channels — no refurbished, no counterfeit, no compromise.

When legacy PLC systems face unplanned downtime, the cost per hour can reach tens of thousands of dollars. The Allen-Bradley 1771-OC addresses this pain point head-on: it slots directly into any PLC-5 chassis slot, is auto-recognized by the controller on power-up, and restores full I/O functionality within minutes. Whether you’re maintaining Oil & Gas infrastructure, Power Plant control loops, or high-speed packaging lines, this module is the Original Spare Parts solution your system demands. 100% Original and Brand New — backed by our 1-Year Warranty and global logistics network.

Contact our team today for real-time pricing, datasheet access, and same-week dispatch. Industrial Automation reliability starts here.

Technical Specifications & Selection Guide

Selection Tip: The 1771-OC is the preferred choice when your field devices require sinking DC outputs in the 10-30V range. For AC output requirements, consider the 1771-OA or 1771-OB series. Always verify chassis backplane compatibility before ordering.

Core Features & Technical Advantages

• Precision Optical Isolation (1500V AC): Shields the PLC System logic from field-side electrical noise, ground loops, and voltage transients — critical in heavy-duty industrial environments.
• Robust 16-Point I/O Density: Maximizes chassis slot utilization, reducing hardware footprint while maintaining full control coverage across field devices.
• Hot-Swap Compatible Design: Removable terminal blocks allow module replacement without full system shutdown, minimizing Mean Time to Repair (MTTR) on active production lines.
• Per-Channel LED Diagnostics: Real-time visual fault indication accelerates troubleshooting — no oscilloscope required for first-pass diagnosis.
• Broad Load Compatibility: Drives solenoid valves, motor starters, indicator lamps, and relay coils with consistent 2A per-point output — no external amplification needed.
• EOL Legacy System Support: Fully compatible with end-of-life PLC-5 platforms still operating in brownfield facilities, extending asset life without costly system migrations.

Typical Application Scenarios

✅ Oil & Gas: Wellhead control panels and pipeline valve actuator systems rely on isolated DC outputs to prevent ground-loop interference across long cable runs. The 1771-OC’s 1500V optical isolation makes it the Control Module of choice for hazardous-area adjacent installations.

Power Plants & Utilities: Turbine auxiliary control and switchgear sequencing demand deterministic output response. With 1ms switching latency, this module integrates seamlessly into DCS-adjacent PLC System architectures managing critical load shedding operations.

✅ Automotive Manufacturing: Body-in-white welding lines and paint shop conveyor systems require synchronized multi-point output control. The 1771-OC’s 16 isolated channels handle simultaneous actuator commands without cross-channel interference.

✅ Pharmaceutical & Food Processing: Hygienic process lines demand reliable dosing pump and valve control with full audit traceability. Original Spare Parts with documented provenance satisfy FDA 21 CFR Part 11 and GMP compliance requirements.

✅ Packaging & Logistics: High-cycle labeling, sealing, and inspection stations benefit from the module’s robust overload protection, sustaining 24/7 operation without output degradation.

Logistics & Professional Service

• ✅ 2-Day Express Shipping Available: Stocked units ship within 24-48 hours via DHL, FedEx, or UPS to minimize your production downtime window.
