Solving the Discontinued Hardware Crisis

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

OEM support for Series 90 hardware has been discontinued. Authorized repair channels have dried up. The practical reality for plant engineers is that the secondary market is the only viable source for this part. Facilities that have not pre-positioned spare inventory face a binary choice when failure occurs: locate a verified unit on the open market under time pressure, or commit to an unplanned system migration. The cost differential between those two outcomes is not marginal.

Extending the operational life of a Series 90 installation by 5 to 10 years through strategic spare parts positioning is a defensible capital allocation decision. The engineering cost of a platform migration — including I/O remapping, software conversion, loop tuning, and validation — routinely exceeds USD 500,000 for mid-size installations. A pre-positioned critical spare at a fraction of that cost is not a maintenance expense; it is asset protection.

Condition & Reliability Assurance

Sourcing obsolete hardware from unvetted channels introduces its own category of risk. DriveKNMS applies a structured 5-step quality process to all legacy modules before dispatch review:

• Step 1 – Visual and Mechanical Inspection: Full board-level examination for physical damage, corrosion, and component displacement.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in legacy PLC hardware. Each unit is evaluated for capacitor condition; units with degraded capacitors are either recapped or rejected.
• Step 3 – Firmware Version Verification: Where applicable, firmware revision is confirmed and documented to ensure compatibility with the target system revision.
• Step 4 – Pin and Connector Inspection: All edge connectors and backplane pins are inspected for oxidation, bending, and contact integrity. Affected contacts are cleaned or the unit is rejected.
• Step 5 – Functional Bench Test: Units are powered and tested under controlled conditions prior to packaging.

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: All units sourced by DriveKNMS are traceable to documented supply channels. Physical markings, board revisions, and component profiles are cross-referenced against known-good references. Counterfeit screening is part of our intake process.

Q: Can you source additional quantity if we need more than one unit?
A: Contact us with your quantity requirement. DriveKNMS maintains sourcing relationships across multiple verified channels and can advise on availability timelines for larger orders.
