الوصف
The GE IS200DSPXH1BD Digital Signal Processor Control Board (DSPX) is a high-performance printed circuit board that acts as a primary real-time controller in GE’s industrial automation systems.1
It is a critical component used in:
- GE Speedtronic Mark VI Turbine Control Systems2
- GE EX2100 Excitation Control Series3
- GE Innovation Series Drives4
🧠 Core Functionality
The DSPX board’s main role is to execute complex, time-critical control algorithms using a dedicated Digital Signal Processor (DSP), ensuring precise and reliable operation of large industrial machinery.5
- Drives Control: It serves as the primary controller for bridge, motor regulator, and gating functions within the Innovation Series drives.6 This involves the precise timing of power semiconductor switches (like IGBTs) to regulate motor speed, torque, and position.
- Generator Field Control: When used in the EX2100 Excitation Control system, the board manages the generator field control applications, which regulate the output voltage and reactive power of synchronous generators.7
- Logic and Processing: The board provides all the necessary logic, processing, and interface functions for the system, replacing traditional analog controls with high-speed, digital processing.8
