GE IS200EXHSG3AEC High-Speed Protection Board | Original Stock

Product Details

Product Overview

The GE IS200EXHSG3AEC functions as a specialized Exciter High-Speed (HS) Relay Driver Board within the GE Mark VI Speedtronic turbine control ecosystem. This module executes rapid-response control and protection routines for synchronous generator excitation. It translates high-level controller commands into high-speed relay actions to regulate excitation voltage and protect the generator during transient load events. We supply this board in 100% Brand New factory condition, ensuring all high-speed switching circuits and galvanic isolation barriers meet original GE aerospace-grade engineering standards.

Technical Specifications

The IS200EXHSG3AEC utilizes a compact form factor designed for high-density integration into the Mark VI exciter rack.

Engineering Advantages

• Ultra-Fast Relay Actuation: The IS200EXHSG3AEC eliminates logic processing bottlenecks by providing a direct, high-speed interface for exciter relays. This rapid response ensures the system stabilizes excitation levels within milliseconds during grid disturbances or sudden load rejections.

• Compact Space Optimization: Measuring only 2.2 cm in width, this module fits into extremely tight control enclosures. Its narrow footprint allows for redundant board configurations in standard racks, maximizing protection without increasing cabinet size.

• Hardened Signal Integrity: Built-in EMI shielding protects the high-speed relay driver logic from the massive electromagnetic fields generated by the excitation power train. This hardening prevents false triggers and ensures clean signal switching in harsh electrical environments.

• Integrated Safety Interlocks: The board monitors for over-voltage and over-current conditions at the hardware level. It executes autonomous protection routines to de-energize excitation loops if it detects a critical fault, safeguarding the generator's rotor and stator windings.

• Direct Mark VI Native Integration: The IS200EXHSG3AEC communicates seamlessly with the Mark VI backplane. This native compatibility allows for real-time diagnostics and status monitoring via the ControlST or ToolboxST software suites.

FAQs

• Does the IS200EXHSG3AEC support hot-swappable replacement?

  Yes. The modular design allows for hot-swappable servicing. Technicians replace the board without de-energizing the entire control rack, which prevents unnecessary turbine trips and maintains continuous plant availability.

• Is the IS200EXHSG3AEC compatible with all Mark VI exciter series?

  This board is a standard component for the Mark VI Exciter High-Speed (EXHS) subsystem. Always verify the revision code (e.g., G3AEC) against your current system configuration to ensure exact firmware and hardware matching.

• How does this board handle thermal stress in power plant environments?

  The IS200EXHSG3AEC maintains stable operation up to +65°C. Its industrial-grade semiconductors and convection-cooled design prevent thermal drift, ensuring consistent relay timing even in non-climate-controlled instrument rooms.

• What is the significance of the "MRP528516" reference?

  MRP528516 is the GE internal manufacturing reference often found on the PCB silk-screen. It identifies the physical board assembly used for the IS200EXHSG3AEC product model, confirming it as an authentic General Electric component.
