Densan DVE-102A

Product Name
Densan DVE-102A industrial graphic board or generic circuit board, depending on supplied revision.
Product Overview
Densan DVE-102A appears in two verified surplus configurations. One listing describes a Densan graphic board with 128 KB SRAM. A separate industrial listing describes DVE-102A with alternative number 9327A as a used circuit board. Confirm the exact sticker, firmware label and connector layout before defining the board as a graphics module or a general-purpose control card.

Description
Technical Specifications
  • Graphic-board configuration: 128 KB SRAM memory.
  • General circuit-board configuration, 9327A: approximately 12 x 9 x 2 inches physical envelope, 2 lbs shipping weight.
  • Bus and connector details: confirm from board silkscreen; Densan VME or proprietary industrial bus according to the host system.
  • Display resolution, refresh rate and interface signaling for the graphic variant are not included in retrieved public documentation.
Key Features
  • Compact industrial PCB suitable for legacy factory systems.
  • SRAM-based graphic buffer for frame storage where the graphic revision is installed.
  • Direct replacement support within systems that originally shipped with DVE-102A/9327A.
Application Scenarios
  • Legacy industrial workstations and operator graphic terminals.
  • Retrofit of obsolete Densan-based automation controllers.
  • Spare-board support for FA equipment, test systems and scientific instruments.
Performance Parameters
  • Memory bandwidth and pixel throughput are determined by the 128 KB SRAM organization in the graphic variant.
  • For the 9327A circuit-board variant, performance values depend on the host backplane firmware and connected I/O.
Material Composition
  • Rigid multilayer FR4 laminate.
  • Surface-mount memory devices, graphic controller or generic logic ICs, connectors and passive components.
  • Anti-tarnish connector plating according to the original manufacturing revision.
Structural Characteristics
  • Edge or header connectors for backplane or cable I/O.
  • Mounting holes aligned with the original chassis or VME bracket.
  • Component layout separated into memory, controller and interface sections.
Working Principle
The graphic variant stores display data in onboard SRAM, processes commands from the host bus, and drives the connected monitor or industrial display interface. The general circuit-board variant processes control or signal data according to the original firmware loaded on its logic devices.
Installation Requirements
  • Power down the host system before installing or replacing the board.
  • Match the connector type, jumper setting and firmware revision to the existing controller.
  • Verify mechanical clearance in the original card cage or enclosure.
  • For graphic use, confirm monitor interface compatibility before system startup.
Usage Precautions
  • Handle only with ESD protection because SRAM and graphic controller devices are static sensitive.
  • Do not mix DVE-102A graphic boards with 9327A generic circuit boards without confirming electrical interchangeability.
  • Inspect for damaged connectors, burned components and corroded contacts before power-up.
  • Store spare boards in anti-static bags with desiccant in a temperature-controlled room.
