GE IS200ESELH1A / IS200ESELH1AAA Exciter Selector Board – Mark VI EX2100 Excitation Control System
When an excitation control system loses its selector logic, the consequences cascade fast: generator field voltage becomes unregulated, AVR redundancy collapses, and the entire power unit risks an unplanned trip. In large-scale power generation facilities — gas turbines, steam turbines, and combined-cycle plants — even a few minutes of unscheduled downtime can cost tens of thousands of dollars. The GE IS200ESELH1A Exciter Selector Board is the critical arbitration component that prevents exactly this scenario, ensuring seamless switching between redundant excitation channels and maintaining continuous, stable generator output.
Within GE’s Mark VI and EX2100 excitation control architecture, the IS200ESELH1A (also catalogued as IS200ESELH1AAA) occupies a pivotal role: it manages the selection logic between primary and backup excitation paths, enabling the TMR (Triple Modular Redundancy) philosophy that defines GE’s turbine control philosophy. As a genuine OEM board from General Electric’s Power Controls division, this module is deployed across hundreds of utility-scale and industrial power plants worldwide, making it one of the most sought-after spare parts in the global turbine controls aftermarket.

Frequently Asked Questions
- Q: What is the difference between IS200ESELH1A and IS200ESELH1AAA?
- A: IS200ESELH1AAA is the full catalog revision suffix of IS200ESELH1A. Both refer to the same physical board and are functionally interchangeable within the Mark VI / EX2100 system.
- Q: Is this board compatible with Mark V systems?
- A: No. The IS200ESELH1A is designed specifically for the Mark VI and EX2100 excitation control platform. Mark V uses a different board architecture. Contact us to identify the correct Mark V equivalent.
- Q: Do you provide a warranty?
- A: Yes. All boards sold by Konmask.com carry a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions.
- Q: Can you ship to my country?
- A: Konmask ships globally via DHL, FedEx, and UPS Express. We handle export documentation including commercial invoice and packing list. Contact us for country-specific shipping options.
- Q: What if the board I receive is not functioning correctly?
- A: Contact support@konmask.com within 30 days of receipt. We will arrange a replacement or full refund after technical review.
