Solving the Discontinued Hardware Crisis

The Emerson DeltaV platform has been deployed across thousands of process facilities worldwide since the mid-1990s. While Emerson continues to support newer DeltaV generations, field-level components such as the KJ4001X1-CJ1 channel terminal block have reached end-of-manufacture. These terminal blocks serve as the physical and electrical interface between DeltaV I/O cards and field instrument wiring. Without them, the I/O card cannot function — regardless of how well the rest of the system is maintained.

DriveKNMS specializes in sourcing and holding inventory of exactly these components — parts that have left the OEM supply chain but remain operationally critical for another 5 to 10 years of asset life.

Condition & Reliability Assurance

Obsolete components sourced from secondary markets carry inherent risk. DriveKNMS applies a structured 5-step quality process before any unit is offered for sale:

Units that do not pass all five steps are not sold. They are either returned to the refurbishment queue or scrapped.

Key Features for System Maintenance

• Drop-in replacement: The KJ4001X1-CJ1 installs directly into existing DeltaV I/O carrier positions without modification to the cabinet, marshalling panel, or field wiring.
• No re-programming required: Channel configuration, tag assignments, and I/O parameters remain intact in the DeltaV controller. Replacing the terminal block does not trigger a re-download or re-commissioning cycle under normal conditions.
• No engineering re-work: Unlike a platform migration, a terminal block replacement is a maintenance-level task. It does not require a controls engineer, a project manager, or a change management process beyond standard MOC documentation.
• Preserves existing field wiring: All existing instrument cables terminate to the same screw positions. There is no re-termination, no re-labeling, and no loop re-verification required beyond standard post-maintenance checks.
• Extends asset life by 5–10 years: A facility that maintains adequate spare inventory of components like the KJ4001X1-CJ1 can defer a full DeltaV migration until a planned capital cycle — rather than being forced into an emergency upgrade by a single component failure.
