Foxboro P0926KQ-A Power Supply Output Cable – Obsolete I/A Series Spare Part

When a power supply output cable fails inside a Foxboro I/A Series distributed control system, the consequences extend far beyond a single module. The I/A Series DCS remains the backbone of continuous-process operations in refining, chemical, and power generation facilities worldwide. A single unplanned outage caused by a failed interconnect cable can halt an entire production line. Conservative industry estimates place the cost of such an event — including lost throughput, emergency engineering labor, and expedited procurement — at several hundred thousand to several million dollars per incident. Replacing the entire DCS to resolve a cable-level failure is an engineering and financial decision that no plant manager should be forced into prematurely. DriveKNMS holds verified physical stock of the P0926KQ-A, a component that Foxboro no longer manufactures. Securing this part now is a direct investment in the operational continuity of your existing asset base.

Technical Specifications

Note: Electrical parameters specific to this cable assembly are not independently published in open documentation. DriveKNMS does not fabricate specifications. Buyers requiring detailed wiring diagrams should reference the original Foxboro I/A Series hardware documentation or contact our technical team.

Solving the Discontinued Hardware Crisis

The Foxboro I/A Series DCS was engineered for decades of service life, and many facilities running this platform have no near-term intention of migrating to a modern DCS — nor should they be forced to. A full DCS migration project routinely carries a price tag of $2 million to $10 million USD when engineering, commissioning, operator retraining, and production downtime are factored in. The P0926KQ-A power supply output cable is a structural interconnect within the I/A Series power distribution architecture. Its failure does not degrade performance gradually — it causes hard faults. Because Foxboro has discontinued this part, procurement teams that wait until failure occurs will face a sourcing window measured in weeks, not days, with no guarantee of availability. The facilities that maintain a controlled spare inventory of components like the P0926KQ-A are the ones that convert what would be a crisis into a two-hour maintenance event.

How to extend your Foxboro I/A Series asset life by 5 to 10 years:

• Audit your cable assemblies now. Power supply output cables are subject to thermal cycling stress over years of operation. A proactive inspection program identifies degradation before it causes a fault.
• Maintain a minimum two-unit spare buffer. For any single-point-of-failure component in a legacy DCS, one spare is a risk. Two spares is a policy.
• Document your installed part numbers. As engineering staff turns over, institutional knowledge of which exact revision (suffix -A, -B, etc.) is installed is frequently lost. Capture this now.
• Negotiate long-lead procurement contracts. Distributors with verified obsolete stock — not brokers offering unverified parts — should be qualified as approved suppliers before you need them urgently.
• Pair cable replacement with capacitor inspection. In aging power supply assemblies, electrolytic capacitor degradation often accompanies cable wear. Addressing both during a planned maintenance window avoids a second outage.

Condition & Reliability Assurance

DriveKNMS applies a structured 5-step quality process to all obsolete and legacy components before shipment:

• Step 1 – Visual and Physical Inspection: Connector pins, cable jacket, and strain relief points are examined for corrosion, cracking, and mechanical deformation.
• Step 2 – Electrolytic Capacitor Assessment (where applicable): Associated power supply assemblies are checked for capacitor bulging, leakage, and ESR deviation — a primary failure mode in components that have been in storage or service for extended periods.
• Step 3 – Firmware and Revision Verification: Part suffix and revision markings are cross-referenced against the original Foxboro bill of materials to confirm compatibility with the target system revision.
• Step 4 – Pin and Contact Integrity Check: All connector contacts are inspected for oxidation and corrosion. Affected contacts are treated or the unit is rejected from saleable inventory.
• Step 5 – Functional Continuity Test: Cable assemblies undergo continuity and insulation resistance testing prior to packaging.

Parts that do not pass all five steps are not offered for sale. Condition is disclosed accurately on every order.

Key Features for System Maintenance

• Drop-in replacement: The P0926KQ-A installs directly into the existing I/A Series power supply chassis with no modification to the host system.
• No reprogramming required: This is a passive cable assembly. Replacement does not trigger any software reconfiguration or controller re-initialization.
• Avoids engineering redesign costs: Using the original Foxboro part number eliminates the need for an engineering change order, third-party cable fabrication, or system re-validation — costs that can easily reach $50,000 or more for a single substitution in a regulated process environment.
• Maintains system certification integrity: Facilities operating under functional safety or process industry standards benefit from using the original manufacturer part number, which preserves the as-built system documentation.

FAQ

What warranty applies to obsolete parts?
DriveKNMS provides a 90-day warranty on tested and refurbished units, and a 30-day warranty on New Old Stock units sold as-is. Warranty terms are confirmed in writing prior to order confirmation.

How do I know the part is genuine and not counterfeit?
All Foxboro parts sourced by DriveKNMS are inspected for authentic manufacturer markings, correct part suffix, and physical construction consistent with genuine Foxboro production. We do not source from unverified secondary markets. Traceability documentation is available upon request for regulated industries.

Should I buy more than one unit?
For a discontinued component with no active production, purchasing a single spare is the minimum prudent action. For facilities with multiple I/A Series cabinets or extended planned maintenance intervals, we recommend evaluating a 2- to 3-unit reserve. Contact us to discuss volume pricing and long-term reservation agreements.

Can you source other Foxboro I/A Series obsolete parts?
Yes. DriveKNMS specializes in hard-to-find and discontinued industrial automation components. If you have a broader bill of materials for your I/A Series system, send it to our team for a consolidated sourcing review.
