Honeywell 51401286-100 Interconnect Cable Assembly for Control Cabinet I/O

The Honeywell 51401286-100 is a factory-terminated interconnect cable assembly typically used inside Honeywell DCS cabinets to link controller or I/O electronics to termination hardware. From my experience, it’s chosen when teams need a drop-in, like-for-like spare that preserves signal integrity and avoids awkward field rework. You might notice that downtime drops simply because the connectors align, the pin-out is right, and the routing behaves as expected in tight cabinets.

Application Fields

This part is suited for Honeywell DCS environments where controller-to-termination or I/O-to-termination connectivity is needed inside panels. Typical applications include:

• Refineries and petrochemicals – cabinet interconnects for analog/digital I/O banks
• Power generation – turbine and balance-of-plant cabinet wiring harnesses
• Chemical and specialty materials – reliable connections for batching and continuous processes
• Pulp & paper, pharmaceuticals, and mining – stable cabinet harnessing where signal integrity matters

Advantages & Value

• Reduced downtime – Plug-and-go fit typically cuts replacement time to minutes.
• Lower installation risk – No ad-hoc crimping or field splicing, fewer wiring errors.
• Lifecycle alignment – Keeps legacy nodes running while planning upgrades on your own schedule.
• Spares rationalization – Clear part identity helps standardize cabinet spares and documentation.
• Support-ready – We help verify cabinet compatibility and routing details before shipping.

A maintenance lead at a Gulf Coast refinery shared that this harness swap “took under 20 minutes including safety checks,” which seems to be typical when the cabinet routing is already known.

Installation & Maintenance

• Verify the exact part number (51401286-100) against your cabinet drawings before opening the panel.
• Power down the affected node and follow lockout/tagout procedures; observe ESD protection, even for passive cables.
• Route the cable along existing paths; maintain minimum bend radius and avoid sharp edges or cable pinch points.
• Use proper strain relief and labeling at both ends; confirm connectors are fully seated and keyed.
• Routine checks: visually inspect connectors during scheduled outages, clean dust from cabinet air paths, and re-seat if vibration is suspected.
• If the connected modules have firmware, apply updates per Honeywell guidance—cable is passive but the system benefits from up-to-date modules.

Quality & Certifications

• Manufactured to Honeywell’s quality standards (ISO 9001-based production systems are typically used across their facilities).
• Component-level item used inside CE/UL certified control systems; RoHS applicability varies by system generation.
• Warranty: 365 days coverage from delivery date.

Related Supporting Components

This cable assembly is commonly paired with Honeywell cabinet hardware such as I/O termination assemblies and I/O processor modules. For example (typical in Experion-based panels):

• CC-TAIX01 – Analog Input IOTA (termination assembly) used to land field AI signals cleanly.
• CC-TDIL01 – Digital Input IOTA for discrete signal terminations.
• CC-PAOH01 – Controller module used in many C300 nodes; often cabled to nearby I/O terminations.

If you share your cabinet photos or a short parts list, we can double-check the harness interface and confirm this 51401286-100 aligns with your I/O stack-up before shipment.
