Solving the Discontinued Hardware Crisis

The GE Mark VI control system was deployed extensively across gas turbines, steam turbines, and combined-cycle power plants from the 1990s through the 2000s. GE has since transitioned its turbine control portfolio to the Mark VIe and beyond, leaving Mark VI hardware — including the IS230SRLYH2A relay output board — without active production support.

The IS230SRLYH2A handles discrete relay output signals within the Mark VI I/O architecture. Its failure directly interrupts the control system's ability to command field devices — actuators, solenoids, and protective relays — that govern turbine operation. There is no software workaround. The board must be physically replaced with an identical or fully compatible unit.

Facilities facing this situation have three realistic options: source a verified spare from the secondary market, cannibalize another unit, or commit to a full platform migration. The first option preserves operational continuity at a fraction of the cost. DriveKNMS exists to make that option viable.

How to extend your Mark VI system life by 5–10 years through strategic spare parts management:

This approach has allowed numerous power generation operators to defer $2–5M control system upgrades by 7–10 years while maintaining full regulatory compliance and operational reliability.

Condition & Reliability Assurance

Every IS230SRLYH2A board supplied by DriveKNMS passes a structured 5-step inspection protocol before dispatch review:

1. Electrolytic Capacitor Assessment — Capacitors are the primary age-related failure point on boards of this vintage. Each unit is inspected for bulging, leakage, and ESR deviation. Boards with degraded capacitors are either recapped or rejected.
2. Firmware Version Verification — The installed firmware revision is read and documented. Customers receive this information prior to shipment to confirm compatibility with their system revision.
3. Pin and Connector Inspection — All edge connectors and I/O pins are examined under magnification for oxidation, corrosion, and mechanical damage. Affected contacts are cleaned or the board is rejected.
4. Functional Bench Test — Where test fixtures are available, boards are powered and relay outputs are exercised to confirm switching function.
5. Packaging for Long-Term Storage — Boards are shipped in anti-static bags with desiccant, inside rigid foam-lined packaging. Boards intended for shelf storage are vacuum-sealed on request.

Key Features for System Maintenance

• Drop-in replacement — The IS230SRLYH2A installs directly into the existing Mark VI rack slot. No rack modification required.
• No reprogramming required — The control system recognizes the board automatically upon installation. Engineering intervention is not required for a standard swap.
• Avoids costly system re-engineering — Replacing this board preserves the existing Mark VI configuration, wiring, and HMI setup. There is no need to retrain operators or re-validate control logic.
• Maintains regulatory compliance continuity — Facilities operating under NERC CIP, ISO, or local grid codes benefit from maintaining the certified control platform rather than introducing a new system mid-certification cycle.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Should I buy more than one unit?
A: For any turbine running on Mark VI, holding at least one spare IS230SRLYH2A on-site is a minimum prudent standard. For facilities with multiple turbines sharing this board type, a centralized spare pool of 2–4 units is a defensible asset protection strategy. Secondary market supply of this part is not guaranteed to remain available.

Q: Can this board be used in both Mark VI and Mark VIe systems?
A: The IS230SRLYH2A is primarily associated with the Mark VI platform. Compatibility with Mark VIe configurations depends on the specific system revision and I/O architecture. Confirm with your system documentation or contact us before ordering.
