Technical Specifications

Note: Electrical parameters not listed here are subject to verification against the original Cooper CN-UIM2 datasheet. DriveKNMS does not publish unverified specifications — contact us for a full technical data package.

Solving the Discontinued Hardware Crisis

The Cooper CN-UIM2 series was deployed extensively in process control and building automation environments during the 1990s and 2000s. These systems were engineered for 20–30 year operational lifespans, and many remain in active service today — managing HVAC, fire suppression, access control, and light industrial process loops. The P3798102-00010 Interface Module serves as the communication bridge between field devices and the CN-series controller backbone. Without it, the entire node loses supervisory visibility.

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

Condition & Reliability Assurance

DriveKNMS applies a 5-step quality assurance process to all refurbished obsolete modules before they leave our facility:

• Step 1 – Visual and Mechanical Inspection: Full board inspection for physical damage, burnt components, cracked solder joints, and connector pin integrity.
• Step 2 – Electrolytic Capacitor Assessment: Aged electrolytic capacitors are the primary failure mode in modules of this era. Each capacitor is tested for ESR (Equivalent Series Resistance) and capacitance drift. Out-of-tolerance capacitors are replaced with equivalent-rated components.
• Step 3 – Firmware Version Verification: Where applicable, firmware revision is confirmed and documented. Modules are not shipped with unknown or mismatched firmware versions.
• Step 4 – Pin and Connector Corrosion Remediation: All edge connectors and backplane pins are inspected under magnification and treated for oxidation. Contact surfaces are cleaned to IPC-610 standards.
• Step 5 – Functional Burn-In Test: Modules undergo a controlled power-on test cycle to confirm stable operation before packaging.

New surplus units are inspected for storage-related degradation and re-sealed in ESD-safe packaging prior to shipment.

Key Features for System Maintenance

• Drop-in replacement: The P3798102-00010 installs directly into the existing CN-series backplane slot with no hardware modification required.
• No reprogramming required: The module retains its original addressing and configuration behavior, eliminating the need for system-level software changes upon installation.
• Avoids engineering reconstruction costs: Replacing this module in-kind costs a fraction of what a forced platform migration would require — no new I/O mapping, no PLC programming, no operator interface redesign.
• Maintains system certification integrity: In regulated environments (pharmaceutical, food processing, utilities), replacing a like-for-like module preserves existing validation documentation. A platform change would require full revalidation.

Q: Should I buy more than one unit?
A: For any obsolete module with no active production, holding a minimum of two spare units is standard practice in industrial maintenance. If your facility operates multiple CN-series nodes, we recommend a quantity assessment based on your installed base. Contact us to discuss a long-term spares agreement.
