GE DS200DSPCH1A Digital Signal Processor Control Board

Configured for high-powered converter applications in GE LS2100 control systems, the GE DS200DSPCH1A (DS200DSPCH1A Digital Signal Processor Control Board) provides direct physical/electrical execution.

Hardware Specifications

Firmware Flash Compatibility and Backplane Bus Communication

• The DS200DSPCH1A board integrates a VME Bus Interface utilized as an optional connector for compatibility with GE Fanuc 90/70 Programmable Logic Controllers (PLCs), functioning as either a VME Bus master or slave.
• Backplane bus communication velocity and firmware flash compatibility require precise revision matching to maintain deterministic control loops across multi-bridge power converters and wind turbine platforms.
• The module supports expandable high-speed input/output interfaces and incorporates an 8K dual-ported SRAM interface controlled via a configurable SRAM-based FPGA device when operating in VME slave mode.
• On-board diagnostics include six status LEDs (IMOK and FAIL indicators plus four project-defined amber LEDs) and dual pushbutton switches (SW1 for DSP hard reset and SW2 for serial boot).

Frequently Asked Questions

Q: Can the DS200DSPCH1A be hot-swapped during active converter operations?

A: No. Power must be fully isolated from the rack slot before module extraction or insertion to prevent backplane bus arbitration faults and live electrical damage.

Q: How is a hardware reset executed locally on the module?

A: A hard reset can be executed by pressing the SW1 pushbutton switch on the front faceplate using a pointed tool such as a pen or pencil.

Q: What is the function of the VME Bus interface on this control board?

A: The VME Bus interface enables communication compatibility with external controllers, allowing the board to operate as a VME master or slave utilizing dual-ported SRAM.

Field Installation Guidelines

Ensure all power feeds and backplane bus supplies are de-energized and locked out before handling the DS200DSPCH1A board. Use proper electrostatic discharge (ESD) wrist grounding straps prior to touching internal component traces or faceplate switches. Slide the printed circuit board smoothly along the designated card guide slots within the LS2100 rack enclosure until the edge connectors fully engage with the backplane receptacle. Secure all mechanical retention fasteners to specified torque limits to withstand industrial vibration profiles before re-applying system power.
