Overview

The GE IS200EXHSG3AEC Exciter High-Speed (HS) Relay Driver Board is a key component in the EX2100 Excitation Control System, part of GE’s Mark VI turbine control platform. This board is responsible for driving high-speed relays that manage rapid switching operations in generator excitation and protection circuits.

Moreover, the EXHS board ensures precise timing and reliable actuation of relays during critical events such as generator trips, de-excitation, or fault isolation. In addition to its core function, it supports diagnostic feedback and integrates seamlessly with other EX2100 modules. Its robust design and high-speed performance make it essential for maintaining generator stability and safety in high-demand environments.

Therefore, the IS200EXHSG3AEC is widely used in gas, steam, and hydroelectric power plants where fast and deterministic relay control is vital.

Technical Data

Typical Applications

• Generator Excitation Systems: Provides fast relay actuation for field flashing, de-excitation, and fault clearing.

• Power Plant Protection: Supports trip and shutdown logic in turbine and generator protection schemes.

• EX2100 Excitation Cabinets: Installed in control racks to coordinate with other excitation and protection boards.

• Industrial Power Systems: Used in high-speed control loops for large rotating machines.

• Retrofit Projects: Compatible with legacy Mark VI systems for system upgrades and replacements.

For instance, during a generator fault, the EXHS board can instantly trigger relay actions to isolate the excitation system, preventing damage and ensuring safe shutdown. In addition, its integration with diagnostic tools allows for real-time monitoring and predictive maintenance.
