Densan DVE-486-22S (9387A)

Product Name
Densan DVE-486-22S(9387A) VME 486-class single-board computer, S variant.
Product Overview
Densan DVE-486-22S(9387A) is listed as a VME SBC, single-board computer PCB, model DVE 486/22S, made in Japan and supplied as working surplus. The S suffix commonly denotes a variant of the DVE-486/22 base model, but the retrieved surplus listings do not publish the exact electrical differences between 22 and 22S.

Description
Technical Specifications
  • Product class: VME single-board computer.
  • Revision: 9387A.
  • Model style: DVE 486/22S.
  • Country of manufacture: Japan.
  • Representative surplus packing data: approximately 12 x 12 x 12 inches, 8 lbs packaged weight.
  • CPU architecture: Intel 80486-class 32-bit x86; exact processor speed, cache and FPU grade not included in retrieved public documentation.
  • Memory, storage, BIOS and VME interface parameters: confirm from the original Densan schematic.
Key Features
  • VME SBC modularity for legacy industrial control.
  • Working-surplus availability with industrial MRO warranty options in selected channels.
  • Matched replacement for systems originally qualified with 486/22S and 9387A labels.
Application Scenarios
  • Semiconductor wafer-equipment controllers.
  • Industrial automation stations and real-time control systems.
  • Legacy test, inspection and factory-computing platforms.
Performance Parameters
  • Performance derives from the installed 486 processor frequency, onboard cache, memory timing and VME transfer mode.
  • Exact I/O throughput, interrupt latency and memory bandwidth must be validated with the original firmware.
Material Composition
  • Multilayer FR4 VME PCB.
  • 80486 processor package, SRAM/DRAM modules, Flash/BIOS, VME interface components and connectors.
  • Industrial-grade passive components rated for extended operation where originally specified.
Structural Characteristics
  • VME edge connector and onboard processor/memory/I/O layout.
  • S-variant hardware differences from base 22 are not detailed in retrieved public documentation; verify by side-by-side schematic comparison.
  • Mounting holes, ejectors and mechanical dimensions compatible with the host VME rack; confirm 6U or double-height from the board silkscreen.
Working Principle
The SBC boots from onboard firmware, configures the 486 processor and VME controller, and exchanges data with backplane masters, I/O modules and memory. The 22S firmware determines master/slave role, interrupt routing and diagnostic behavior.
Installation Requirements
  • De-energize the VME chassis before card insertion.
  • Confirm 9387A revision, 22S model label, memory population and jumper settings.
  • Verify VME slot compatibility, power rails and cooling clearance.
  • Install the approved BIOS, operating system and VME driver configuration.
Usage Precautions
  • Use ESD-safe handling for processor, memory and VME connectors.
  • Do not assume 22S and 22 non-S boards are electrically identical; match full part numbers.
  • Check for capacitor aging, battery degradation, firmware corruption and connector oxidation before startup.
  • Store spare boards in anti-static packaging with controlled humidity.
