The GE IS200DSPXH1DBC Digital Signal Processor Control Board (DSPX) is a core component in GE’s industrial control platforms, serving as the primary real-time controller for high-speed, precision applications in power generation and industrial drives.1
The suffix H1DBC denotes the specific hardware and artwork revisions (D, B, and C) for this board.2
🧠 Core Functions and Applications
The DSPX board’s function centers on executing complex, time-critical control algorithms using its dedicated Digital Signal Processor (DSP), making it vital for system stability and high performance.3
- Generator Field Control: It is a key board in the GE EX2100 Excitation Control Series, managing the generator field control applications to regulate the output voltage and reactive power of large synchronous generators.4
- Industrial Drives Control: It acts as the primary controller for bridge, motor regulator, and gating functions within GE’s Innovation Series Drives.5 This involves precise timing and control of the power semiconductor switches (IGBTs) to regulate motor speed, torque, and position.6
- System Integration: It provides the necessary logic, processing, and interface functions for the system, often working alongside other controllers like the ACLA board.7
⚙️ Key Technical Features
The IS200DSPXH1DBC is engineered for industrial reliability and high-speed processing:8
| Feature | Details |
| Processor | High-performance 60 MHz Digital Signal Processor (DSP) |
| Compatible Systems | GE Speedtronic Mark VI Turbine Control, EX2100 Excitation Control, Innovation Series Drives |
| Memory | Dedicated FLASH (for boot code and system history), RAM (for execution), and NVRAM (for nonvolatile configuration data). |
| I/O Inputs | Includes five differential HIFI (High-Frequency Input) pairs for signals like tachometer feedback or counter readings. |
| Interfaces | Features multiple serial interfaces, including two high-speed ISBus interfaces (5 Mb/s) for communication with other system boards. |
| Protection | Equipped with a watchdog timer and interrupt handling (e.g., stack overflow) to detect critical faults and initiate a protective reset. |
The board is typically a single-slot, 3U high module that mounts directly into the control rack and is often protected with a conformal coating for environmental robustness.9
