Solving the Discontinued Hardware Crisis

Woodward MicroNet TMR and MicroNet Plus systems were deployed extensively across power generation, oil & gas, and petrochemical facilities throughout the 1990s and 2000s. These platforms were engineered for long service lives, and many installations remain in active operation today — controlling assets that represent tens of millions of dollars in capital investment.

The problem is straightforward: Woodward has discontinued the MicroNet product line. Replacement modules such as the 5462-758B are no longer manufactured. When a unit fails, the facility faces a binary choice: locate a verified spare from the secondary market, or commit to a full control system replacement project.

A control system replacement on a turbine train is not a maintenance event. It is a capital project. Engineering studies, new hardware procurement, factory acceptance testing, site installation, loop checks, and commissioning typically require 12 to 24 months of planning and execution. During that window, the affected unit may be forced into reduced-load operation or taken offline entirely. For a baseload power plant or a critical compressor in a gas processing facility, that exposure is unacceptable.

Sourcing a replacement 5462-758B from a qualified supplier eliminates that exposure. The module slots into the existing chassis, restores full system functionality, and allows the facility to defer the migration decision to a planned outage on its own schedule — not one dictated by an unplanned failure.

Condition & Reliability Assurance

Obsolete industrial control modules sourced from the secondary market carry inherent risk. DriveKNMS applies a five-step incoming inspection process to every unit before it is offered for sale:

Step 1 – Visual and Mechanical Inspection: Each board is examined under magnification for physical damage, cracked solder joints, burned components, and connector pin corrosion. Units with visible damage are quarantined and not offered for sale.

Step 2 – Electrolytic Capacitor Assessment: Electrolytic capacitors are the most common failure point in aged industrial electronics. We inspect for bulging, leakage, and ESR deviation. Capacitors showing degradation are flagged for replacement before the unit is cleared.

Step 3 – Firmware and Label Verification: Where accessible, firmware revision markings and hardware revision labels are recorded and cross-referenced against known MicroNet compatibility matrices. Mismatched revisions are disclosed to the buyer before dispatch review.

Step 4 – Connector and Pin Integrity Check: All edge connectors and backplane pins are inspected for oxidation, bending, and contamination. Affected contacts are cleaned using appropriate methods; units with structural pin damage are rejected.

Units that pass all five steps are classified as Inspected Surplus. Units that require component-level refurbishment before passing are classified as Refurbished and priced accordingly. The classification is disclosed on every order confirmation.

Key Features for System Maintenance

The 5462-758B is a direct hardware replacement for the same part number within MicroNet TMR and MicroNet Plus chassis. Key maintenance advantages include:

Q: How do I know the unit is genuine Woodward and not a counterfeit?
A: All units are inspected for Woodward part markings, revision labels, and board construction consistent with known authentic examples. We do not source from unverified brokers. If you require additional authentication documentation, contact us before quotation confirmation.

Q: Can you source other MicroNet modules?
A: Yes. DriveKNMS specializes in obsolete and hard-to-find industrial control components across multiple platforms. Contact us with your full bill of materials and we will advise on availability.
