Power Generation Exciter Control Solution – GE IS200AEPCH1ABC & IS200BPPBH2BJD | Mark VI Series
Where This Product Is Used
The GE IS200AEPCH1ABC and IS200BPPBH2BJD are paired exciter control modules deployed within GE’s Mark VI Turbine Control System. They are engineered for mission-critical environments including:
- Gas turbine power plants — generator excitation regulation and AVR (Automatic Voltage Regulator) control loops
- Combined-cycle power stations — coordinated exciter feedback between gas and steam turbine trains
- Industrial co-generation facilities — on-site power generation with grid synchronization requirements
- Utility-scale generation assets — baseload and peaking units requiring high-availability excitation control
- Offshore & onshore oil and gas platforms — generator sets with Mark VI-based control architecture
These modules are integral to maintaining generator terminal voltage stability, reactive power output, and protection against over-excitation or under-excitation faults.

Why Engineers Specify This Model
- Proven Mark VI architecture — drop-in compatible with existing GE Mark VI exciter cabinets; no firmware re-engineering required
- Dual-module pairing — IS200AEPCH1ABC handles excitation logic processing while IS200BPPBH2BJD manages power distribution and backplane I/O, providing functional redundancy at the board level
- High MTBF design — conformal-coated PCB suitable for humid, dusty, and vibration-prone power plant environments
- Fast commissioning — plug-and-play replacement within Mark VI exciter panel; no custom calibration required for standard AVR configurations
- Long service life — supports legacy Mark VI installations still operating at 15–25 year-old power assets where OEM lead times are 26+ weeks

Application-Specific FAQ
Q: Are IS200AEPCH1ABC and IS200BPPBH2BJD sold as a set or individually?
A: Both modules are available individually or as a matched pair. For exciter panel replacements, we recommend sourcing both simultaneously to ensure firmware and hardware revision compatibility.
Q: What Mark VI exciter frame is this compatible with?
A: These modules are designed for GE EX2100 and EX2100e exciter systems integrated with Mark VI turbine control. Compatibility with Mark VIe should be confirmed against your specific panel revision — contact us for verification.
Q: Can Konmask provide a test report before shipment?
A: Yes. Functional test reports are available upon request at no additional charge for orders of 2 or more units.
Q: What is the lead time for in-stock units?
A: In-stock units ship within 3–5 business days of payment confirmation. For out-of-stock items, typical sourcing lead time is 2–4 weeks.
Q: Do you accept returns?
A: Yes, within 30 days of receipt for units in original, uninstalled condition. Defective units are covered under our 90-day warranty policy.
