The GE DS3800XPEN is a Small Electronics Backplane Card for the GE Speedtronic Mark IV turbine control system. Its main purpose is to serve as a compact central hub, providing a dedicated and organized platform for smaller electronic modules to plug into.
This card’s function is to distribute power and provide electrical communication pathways, or buses, for various specialized circuit boards. It acts as the backbone for the system’s “small electronics,” allowing them to communicate with the main processor and other components without the need for complex and messy point-to-point wiring. This modular design simplifies the system’s architecture, making it more robust and easier to maintain.
Key Functions & Features
- Modular Connectivity: The DS3800XPEN provides a series of slots and connectors for other circuit boards to plug into. This modularity allows for a flexible system that can be configured for different applications.
- Power Distribution: The card receives power from the main power supply and distributes it to the modules plugged into it, ensuring each component receives the correct voltage to operate.
- Signal Routing: It provides a shared electrical bus that allows different cards to communicate with each other and with the system’s central processor.
- Physical Form Factor: It is a small form-factor card, which means it is designed for applications where space is limited.
Technical Specifications (Inferred)
While detailed public specifications are scarce due to the age of the Mark IV system, we can infer some key attributes based on its function and series:
- Part Number: DS3800XPEN
- Series: GE Speedtronic Mark IV
- Product Type: Small Electronics Backplane Card
- Function: Provides a central hub for power and data for other small electronic modules
- Application: Used in gas and steam turbine control systems.
Related Components
As a backplane card, the DS3800XPEN is central to the system’s operation and interacts with nearly all other cards, including:
- Processor Cards: The main processing unit, such as the DS3800HCDA, plugs into the backplane to communicate with other I/O cards.
- I/O (Input/Output) Cards: Various I/O cards, such as thermocouple, digital, and analog I/O boards, connect to the backplane to send and receive data from field devices.
- Power Supply Cards: Power cards like the DS3800NTRF would connect to the backplane to supply the necessary power to all the other modules.
