Functional Description

IS200DSPXH1DAA is a Digital Signal Processor Control Board developed by GE. It is a part of EX2100 control system. The Digital Signal Processor Control Board (DSPX) is a central and integral component in control systems, specifically designed to manage the bridge and motor regulator functions, as well as handle gating operations for Innovation Series drives. Its robust digital signal processing capabilities make it a cornerstone for regulating and managing the performance of bridge and motor functions within Innovation Series drives.


  • Bridge Regulation: One of the primary functions is to regulate the operation of the bridge. This involves controlling the flow of power within the system, ensuring optimal efficiency, and maintaining the desired performance parameters. The DSPX utilizes advanced algorithms and digital signal processing techniques to achieve precise regulation.
  • Motor Regulation: Dedicated to overseeing the motor regulator functions. It monitors and controls the operation, adjusting parameters such as speed, torque, and position as required by the application. This capability allows for a high level of customization and adaptability to various industrial processes.
  • Gating Functions: Refer to the process of controlling the opening and closing of semiconductor switches in the drive system. The board takes on the responsibility of efficiently managing these gating functions, ensuring the proper modulation of power and smooth transitions between states.
  • Innovation Series Drives Compatibility: Specifically designed for compatibility with Innovation Series drives, the board aligns with the innovative features and advanced technologies incorporated into these drives. It optimizes the performance of the entire drive system, contributing to enhanced efficiency and reliability.
  • Digital Signal Processing (DSP) Capabilities: Leveraging sophisticated digital signal processing capabilities, the board executes complex algorithms and computations in real-time. This ensures that the control system responds dynamically to changing conditions, maintaining stability and precision in the regulation of bridge and motor functions.
  • Adaptive Control Strategies: It employs adaptive control strategies, allowing it to dynamically adjust parameters based on real-time feedback and system requirements. This adaptability ensures optimal performance across a range of operating conditions, enhancing the overall efficiency of the control system.
  • Integration with Control Networks: Seamlessly integrates with control networks, facilitating communication and coordination with other components within the system. This interconnectedness enhances the overall functionality and coordination of the control system.
  • Robust Fault Detection and Diagnostics: The board incorporates advanced fault detection mechanisms and diagnostics. In the event of anomalies or system irregularities, the board can identify and report issues promptly, enabling swift troubleshooting and preventive maintenance.
  • Firmware Upgradability: Designed to accommodate firmware upgrades, allowing for future enhancements and feature additions. This adaptability ensures that the board remains aligned with evolving industry standards and technology advancements.

Board Replacement Procedure (Online)

  • In the scenario of a redundant control system, replacing a failed DSPX while the exciter is in operation is a feasible task. The option exists to maintain the failed DSPX in its place, enabling the exciter to operate on the remaining controller. However, it is essential to note that in the unlikely event of a second board failure in a different controller, the exciter will undergo an automatic shutdown.
  • Identification of Failed Board: Open the control cabinet door and confirm the failed DSPX by referring to the indicators on the front of the board.
  • Caution: Exercise care during the replacement process as other controllers, power supplies, and terminal boards remain energized and active.
  • De-energize Control Rack Section: De-energize the section of the control rack (either controller M1, M2, or C), following the procedure specified for the particular EX2100 type under service. Ensure that the LED indicators on the corresponding section of the EPSM are off.
  • Control Transfer Confirmation: Check the controller LEDs to confirm that control has been transferred to the other master. Verify that all power indicators on the boards in the control rack containing the DSPX to be replaced are off before interacting with the DSPX or any connected circuits.
  • Disconnect Communication Cables: Disconnect the fiber-optic communication cables from the front panel.
  • Removal of DSPX and EISB Boards: Carefully remove the DSPX board and the attached EISB board from the control rack:
    • a. Loosen the screws at the top of the DSPX faceplate and the bottom of the EISB faceplate, near the ejector tabs (Note: Screws are captive and should not be removed).
    • b. Unseat the DSPX and attached EISB by raising the ejector tabs.
    • c. Using both hands, gently pull both boards from the rack.
  • EISB Replacement: Remove the EISB from the bottom of the DSPX and attach it to the replacement DSPX.
  • Installation of Replacement: Slide the replacement board and EISB board into the correct slot in the rack.
  • Initiate the seating process by firmly pressing the top and bottom of the faceplates simultaneously with your thumbs.
  • Final Seating of the Module: Complete the seating by starting and alternately tightening the screws at the top and bottom of the faceplate assembly. Ensure even tightening to guarantee the module is seated squarely.
  • Functional Testing: Test the replaced DSPX by transferring control from the active master to the inactive master. Observe and confirm correct operation.
    Power Restoration: Apply power to the appropriate section of the control rack from the EPDM. Check that the LED power indicators on the EPDM and EPSM illuminate. Verify that
  • the green power LEDs on the adjacent controller boards also illuminate.
  • Reconnection of Communication Cables: Reconnect all communication cables that were disconnected during the removal of the old module.
