Technical Specifications

Solving the Discontinued Hardware Crisis

The Kongsberg RAIC400 was designed for use in distributed control environments where remote analogue signal acquisition is a foundational requirement. In these architectures, the module handles field-level signal conditioning and transmission to the central processing layer. There is no generic substitute that integrates without engineering intervention.

Facilities running Kongsberg legacy DCS platforms face a structural problem: the OEM has discontinued support, third-party repair capacity is shrinking, and the installed base of these systems remains large. Plant managers who have deferred system upgrades — a rational decision given capital expenditure constraints — now find themselves in a position where a single module failure can trigger a forced, unplanned migration.

The strategic response is not to accelerate that migration on a crisis timeline. It is to maintain a controlled inventory of verified spare parts that extends the operational life of the existing system by 5 to 10 years, allowing the facility to plan and budget a migration on its own schedule rather than under production pressure.

Condition & Reliability Assurance

Obsolete parts sourced outside OEM channels carry inherent risk. DriveKNMS applies a structured 5-step inspection protocol before any unit is offered for sale:

• Step 1 – Visual and Mechanical Inspection: Physical examination for board damage, connector wear, and housing integrity.
• Step 2 – Electrolytic Capacitor Assessment: Aged electrolytic capacitors are a primary failure mode in legacy electronics. Each unit is evaluated for capacitor condition, with replacement performed where degradation is identified.
• Step 3 – Firmware Version Verification: Where applicable, firmware revision is confirmed and documented to ensure compatibility with the target system configuration.
• Step 4 – Pin and Connector Corrosion Check: All connector pins are inspected under magnification for oxidation and corrosion. Affected contacts are cleaned or the unit is rejected.
• Step 5 – Functional Bench Test: The unit is powered and tested against known-good reference parameters before dispatch.

Units that do not pass all five stages are not offered for sale. Condition grade is documented and provided with each shipment.

Key Features for System Maintenance

Q: Should I purchase more than one unit?
A: For any module classified as obsolete, maintaining a minimum of two units in reserve is standard practice. The cost of a second unit is negligible relative to the cost of a production stoppage while sourcing a replacement under time pressure. For facilities with multiple identical systems, a proportional buffer is recommended.
