Technical Specifications

Note: Electrical parameters not independently verified by DriveKNMS. Buyers are advised to cross-reference the original ALPHI datasheet for precise electrical specifications prior to installation.

Solving the Discontinued Hardware Crisis

ALPHI Technology's PCI-4PACK series was widely deployed in industrial PC platforms requiring reliable multi-channel PCI bus expansion — particularly in environments where ruggedized, deterministic I/O performance was non-negotiable. These systems were built to last decades, and many remain in active service inside petrochemical plants, power generation facilities, semiconductor fabs, and defense-adjacent manufacturing lines.

For plant managers and reliability engineers operating under capital expenditure constraints, the calculus is not complicated. A single verified spare part, sourced and held in the maintenance storeroom, can extend the operational life of an entire control node by five to ten years. The cost of that spare is measured in thousands. The cost of the alternative is measured in millions — and that figure does not include the production revenue lost during the transition period.

DriveKNMS operates specifically within this gap. We source, inspect, and supply discontinued industrial components to facilities that have made the deliberate decision to protect their existing automation assets rather than replace them prematurely.

Condition & Reliability Assurance

Every PCI-4PACK 736-5-001 unit that leaves our facility has passed a structured five-stage inspection protocol developed for legacy PCB-based hardware:

Stage 1 – Visual and Mechanical Inspection: Full board examination for physical damage, cracked solder joints, delamination, and connector integrity. Any unit with compromised mechanical condition is rejected at this stage.

Stage 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in legacy PCI hardware. Each board is inspected for capacitor bulging, electrolyte leakage, and ESR deviation. Suspect capacitors are flagged and, where applicable, replaced with equivalent-specification components.

Stage 3 – Firmware and Revision Verification: Where accessible, firmware revision markings and EEPROM identifiers are documented and cross-referenced against known-good revision records. This step ensures the unit delivered matches the hardware revision expected by the host system.

Stage 4 – Pin and Connector Corrosion Check: PCI edge connectors and any auxiliary I/O pins are inspected under magnification for oxidation and corrosion. Affected contacts are treated with appropriate contact cleaning agents. Units with irreversible connector damage are not offered for sale.

Key Features for System Maintenance

The PCI-4PACK 736-5-001 is a direct hardware replacement for the original ALPHI module. There is no firmware migration, no driver rewrite, and no re-engineering of the host system required. The replacement drops into the existing PCI slot and the host system recognizes it as the original hardware — because it is the original hardware.

For facilities that have standardized on a specific hardware revision, we can document the revision of each unit prior to shipment, allowing maintenance planners to confirm compatibility before the part arrives on site.
