GE DS3800HRMA DUAL PORTER BYTE RAM

The primary function of the DS3800HRMA is to provide a memory space that can be accessed by two different processors or controllers at the same time. This is critical in a complex industrial control system where different modules need to read from or write to the same data space simultaneously. The “dual ported” design of the card allows for:

  • Real-Time Data Sharing: It enables real-time data to be shared quickly and efficiently between two different processors.
  • Synchronization: It handles synchronization and arbitration, ensuring that multiple devices can access the memory without corrupting the data.
  • Efficient Communication: It offloads communication tasks from the main processors, allowing them to focus on their primary control functions.

الوصف

The GE DS3800HRMA is a specialized Dual Ported Byte RAM Card used in the GE Speedtronic Mark IV series of turbine control systems. It is a legacy component, 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 DS3800HRMA is to provide a memory space that can be accessed by two different processors or controllers at the same time. This is critical in a complex industrial control system where different modules need to read from or write to the same data space simultaneously. The “dual ported” design of the card allows for:

  • Real-Time Data Sharing: It enables real-time data to be shared quickly and efficiently between two different processors.
  • Synchronization: It handles synchronization and arbitration, ensuring that multiple devices can access the memory without corrupting the data.
  • Efficient Communication: It offloads communication tasks from the main processors, allowing them to focus on their primary control functions.

 

Technical and Design Features

 

The DS3800HRMA 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.
  • Dual-Ported RAM: The card’s name “Dual Ported Byte RAM” indicates that it provides two or more independent access ports. This allows different components to access the same memory location simultaneously, increasing data throughput and system efficiency.
  • Connectors: The board features connectors that allow it to interface with the backplane of the Mark IV control rack, enabling communication with other cards in the system.
