GE DS3800HMPK MKIV, Microprocessor Card

The DS3800HMPK is a robust, industrial-grade circuit board designed to operate in a demanding environment.

  • Legacy Part: The “DS3800” prefix indicates that it belongs to the legacy Mark IV series, which was GE’s first microprocessor-based gas turbine control system, introduced in the 1980s.
  • Connectors: The board features two 50-pin connectors and a 34-pin connector that allow it to interface with other boards and system components. The 50-pin connectors are often used with ribbon cables.
  • Thermal Management: The microprocessor on the board generates heat, and the board is designed with considerations for cooling. Adequate airflow is necessary to prevent overheating, which can compromise the reliability or damage the microprocessor.
  • Jumpers: It is equipped with jumpers that allow technicians to configure its operational settings to match the specific requirements of a given application.

الوصف

The GE DS3800HMPK is a specialized Microprocessor Card used in the GE Speedtronic Mark IV series of turbine and generator control systems. It is a legacy part, no longer in production, and is primarily found on the surplus and refurbished markets for the maintenance and repair of older systems.


 

Function and Purpose

 

The primary function of the DS3800HMPK is to provide the main processing power for a specific module within the Mark IV system. It’s a key component of the system’s distributed control architecture, allowing it to perform real-time calculations and execute complex control logic for a particular function. Its key roles include:

  • Computation: The board is built around a microprocessor, allowing it to execute the control algorithms and perform real-time calculations for a dedicated part of the turbine control system.
  • Control: It manages the operation of connected hardware, such as I/O cards, and communicates with the system’s main processors.
  • Firmware and Data Storage: It contains EPROM (Erasable Programmable Read-Only Memory) modules that store the board’s firmware and configuration data. This allows for updates and adjustments to the system’s programming.
  • Diagnostics: The board includes diagnostic features and indicator LEDs (three red and one amber) to provide a quick visual status of its health and activity.
