Exciter Control Solution – GE IS200EXHSG3AEC | Mark VI Series
The GE IS200EXHSG3AEC is a high-speed relay driver board engineered for the GE Mark VI Turbine Control System. Designed to interface directly with the exciter subsystem, this board manages relay switching events with precision timing critical to generator excitation control in power generation environments.
Where This Product Is Used
The IS200EXHSG3AEC is deployed in facilities where reliable exciter control is non-negotiable:
- Gas Turbine Power Plants – Controls excitation relay sequences during startup, load transitions, and shutdown of GE Frame 6B, 7E, 7FA, and 9E turbines.
- Combined Cycle Power Plants (CCPP) – Integrated into Mark VI panels managing both gas and steam turbine excitation loops.
- Industrial Cogeneration Facilities – Used in on-site power generation systems requiring tight exciter relay timing for grid synchronization.
- Utility-Scale Generator Upgrades – Replacement board for aging Mark V systems migrating to Mark VI architecture.
- OEM Turbine Skid Packages – Installed in factory-built turbine control enclosures by GE-authorized integrators.

Application-Specific FAQ
Q: Is the IS200EXHSG3AEC compatible with Mark V systems?
A: No. This board is designed specifically for the Mark VI architecture. Mark V systems use a different exciter relay driver (DS200-series). Contact us if you need Mark V equivalents.
Q: What does the G3AEC revision suffix indicate?
A: The revision suffix identifies the hardware iteration. G3AEC is a later revision with updated relay driver circuitry. Always match the revision to your panel’s engineering drawing to ensure compatibility.
Q: Can this board be repaired if a relay driver fails?
A: Component-level repair is possible but not recommended for safety-critical exciter applications. We recommend stocking a tested spare and returning the failed unit for evaluation.
Q: Do you offer exchange pricing?
A: Yes. Send us your failed IS200EXHSG3AEC core and receive a credit toward a tested replacement. Contact us for exchange program details.
Q: What is the lead time if the part is not in stock?
A: Typical sourcing lead time is 5–15 business days depending on global surplus availability. We maintain an active sourcing network for GE Mark VI components.
