Honeywell 51304485-150 – Field I/O Termination Cable Assembly for TDC/Experion Cabinets

The Honeywell 51304485-150 is commonly supplied as a pre-terminated I/O termination cable assembly used in Honeywell DCS cabinets (TDC 3000 and many Experion legacy panels). From my experience, the “-150” suffix typically denotes a length variant suited for short cabinet-to-termination runs, giving you a neat, factory-terminated link between the controller-side I/O module and the field termination assembly without crimping on site. It’s a straight, practical spare that gets channels back online fast with minimal wiring risk.

Company’s Order Placement Process and Guarantees

• Delivery time: 1 week if in stock; no more than one month at the latest
• Payment terms: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Factory-terminated harness – Reduces wiring errors and speeds cabinet work; no field crimping in most cases.
• Form-fit-function for Honeywell DCS – Designed for legacy TDC/Experion I/O terminations, easing one-for-one replacement.
• Stable signal routing – Shielding and drain continuity (as applicable by variant) help maintain signal integrity for analog and discrete I/O paths.
• Cabinet-friendly bend radius – Typically suited for short inter-panel runs with tidy routing and strain relief.
• Quick outage recovery – In many cases, swapping a damaged harness restores I/O channels within minutes.

Application Fields

You’ll typically see the 51304485-150 in process industries running Honeywell DCS: refining, chemicals, power generation, pulp & paper, and pharmaceuticals. It’s used during panel builds, I/O expansions, or maintenance swaps where a clean, known-good harness is preferable to field-terminated wiring. One customer in utilities mentioned it shaved hours off a turnaround because the pre-terminated ends eliminated rework on a dozen DI points.

Advantages & Value

• Reliability – Factory terminations reduce intermittent faults that sometimes show up with hand-crimped connectors.
• Compatibility – Matched to Honeywell cabinet hardware, so it usually drops in without pinout changes.
• Cost & downtime savings – Faster swap times and fewer troubleshooting cycles during outages.
• Support-ready – We can help verify the variant against your cabinet drawings and I/O list to avoid mismatches.

Installation & Maintenance

• Environment – Install in a clean control cabinet with adequate ventilation; avoid sharp bends and tight cable trays.
• Wiring – De-energize the cabinet before handling; observe ESD precautions near I/O cards.
• Routing – Maintain bend radius as per typical harness guidelines; use tie-downs and keep away from high-voltage runs where possible.
• Verification – After installation, perform a quick point check (continuity or loop check) on critical channels.
• Upkeep – Periodically inspect connectors for latch wear, ensure shields/drains (if present) remain intact, and re-seat during planned shutdowns if channels show noise.

Quality & Certifications

These assemblies are generally produced to Honeywell’s industrial quality standards and, in many cases, align with CE and RoHS requirements for components used within control cabinets. UL/CSA recognition may apply to the cable/connector materials depending on the production lot. Warranty is 365 days from delivery. If certification sheets are needed for your documentation package, we’ll match the exact lot to the paperwork.

You might notice that availability varies by region; if your site uses a specific length variant, sharing the cabinet drawing or BOM helps confirm that 51304485-150 is the right fit. I’m happy to cross-check pinouts and routing so you receive the correct harness the first time.
