Solving the Discontinued Hardware Crisis

For facilities still running Westinghouse-based control architectures, this creates a hard operational reality: the next board failure may have no direct replacement path through conventional channels. The alternative — a full system retrofit — demands capital expenditure, extended engineering timelines, and production shutdowns that most operations cannot absorb on short notice.

The calculus is straightforward: the cost of one verified spare is a fraction of one day of unplanned production loss.

Condition & Reliability Assurance

DriveKNMS applies a structured 5-step quality process to all obsolete boards before dispatch review:

• Step 1 – Visual and Physical Inspection: Full board examination for mechanical damage, solder joint integrity, and component seating.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in legacy PCBs. Each board is evaluated for capacitor condition; degraded capacitors are replaced with specification-matched components.
• Step 3 – Firmware and Configuration Verification: Where applicable, firmware version is confirmed against known compatible releases for the target system.
• Step 4 – Pin and Connector Corrosion Check: All edge connectors and pin interfaces are inspected and cleaned. Corroded contacts are treated or flagged for disclosure.
• Step 5 – Functional Bench Test: Boards are powered and tested under controlled conditions prior to packaging.

Each unit ships with a condition report. No board leaves our facility without passing all five checkpoints.

Key Features for System Maintenance

• Drop-in Replacement: The 7379A31G05 installs directly into the original board slot. No hardware modification required.
• No Reprogramming Required: Original firmware and configuration are preserved, eliminating the need for system re-commissioning after installation.
• Zero Engineering Redesign Cost: Unlike a system retrofit, a like-for-like board replacement requires no new engineering drawings, no updated safety certifications, and no retraining of operations staff.
• Immediate Deployment Readiness: Boards are tested and packaged for immediate installation upon receipt.
• Long-Term Spare Holding: DriveKNMS can discuss multi-unit procurement for facilities seeking to build a strategic spare buffer against future failures.

Extending Asset Life: A Maintenance Strategy for Legacy Westinghouse Systems

Plant managers facing pressure to decommission aging Westinghouse control systems often underestimate the true cost of early retirement. A structured spare parts strategy — built around identified critical single points of failure like the 7379A31G05 — can defer that capital expenditure by a measurable margin.

This is not a workaround. It is standard practice in industries where capital equipment carries a 20-to-30-year service expectation. Petrochemical, power generation, water treatment, and heavy manufacturing facilities routinely operate on this model. The investment in critical spare inventory is consistently lower than the cost of a single unplanned outage — and orders of magnitude lower than a forced system migration.

For Westinghouse legacy systems specifically, the 7379A31G05 control circuit board represents exactly the type of component that warrants strategic stocking. Its function is central to system operation. Its availability on the open market is declining. The window for cost-effective sourcing is narrowing.
