Solving the Discontinued Hardware Crisis

Woodward's MicroNet platform was the backbone of turbine control across power generation, oil & gas, and industrial compression for over two decades. The platform's architecture — built around dedicated power supply rails feeding control, I/O, and communication modules — means that a single failed power supply does not just take down one card. It takes down the entire control chassis.

Woodward has transitioned its product line toward the MicroNet Plus and NetCon 5000 platforms. Spare parts for the original MicroNet series, including the 80026-172-23-R, are no longer manufactured. Facilities that have not yet migrated — and many have not, given the capital cost and operational risk of a live system cutover — are entirely dependent on the secondary market for continued operation.

The strategic reality for plant managers is straightforward: a single verified spare of the 80026-172-23-R on the shelf represents an insurance policy against an unplanned outage that could last weeks while a replacement is sourced. The cost of that spare is a fraction of one day of lost generation or production revenue.

How to extend your Woodward MicroNet system life by 5–10 years without a full platform migration:

Condition & Reliability Assurance

Sourcing discontinued power supply modules from the secondary market carries real risk. DriveKNMS applies a structured 5-step qualification process to every 80026-172-23-R unit before it is offered for sale:

1. Electrolytic Capacitor Inspection: Power supply modules of this age are susceptible to capacitor degradation. Each unit undergoes ESR (Equivalent Series Resistance) testing to identify aged or failing capacitors before the unit leaves our facility.
2. Firmware Version Verification: The installed firmware revision is documented and disclosed. Customers receive this information prior to shipment to confirm compatibility with their installed system.
3. Connector and Pin Integrity Check: All edge connectors and backplane pins are inspected under magnification for corrosion, oxidation, and mechanical damage. Affected contacts are cleaned or the unit is rejected.
4. Functional Power-On Test: Where test fixtures are available, units are powered and output rails are measured against published tolerances.
5. Cosmetic and Label Verification: Original Woodward part labels, revision markings, and date codes are verified and photographed. Full documentation is provided with each shipment.

Key Features for System Maintenance

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: How do I know the unit is genuine and not a counterfeit?
A: Each unit is inspected for original Woodward labeling, date codes, and board markings. We provide photographic documentation of the physical unit prior to shipment. Customers may request pre-shipment inspection photos before payment is confirmed.

Q: Should we buy more than one unit?
A: For any facility with active MicroNet systems, holding a minimum of two units is a defensible maintenance position. Secondary market availability of this specific part number will not improve over time. Facilities that have experienced one power supply failure statistically face a higher probability of a second failure in aging hardware.
