GE IS200ERSDG1A — Exciter Regulator Signal Distribution Board | Mark VI / EX2100 Series
Engineering Background
The IS200ERSDG1A is a purpose-engineered signal distribution board developed by GE (General Electric) as a core component within the EX2100 digital excitation control system and the Mark VI turbine control platform. It serves as the critical interface layer between the exciter regulator controller and downstream field devices, managing analog and digital signal routing with high-fidelity isolation and noise immunity — essential in high-voltage generator environments.
Product Positioning
Designed for power generation OEMs, EPC contractors, and plant maintenance teams operating GE Frame turbines, combined-cycle plants, and industrial generator sets. The IS200ERSDG1A is a direct OEM replacement board, ensuring full backward compatibility with existing Mark VI and EX2100 control cabinets without firmware modification or hardware adaptation.

System Architecture & Signal Flow
Within the EX2100 excitation control cabinet, the IS200ERSDG1A occupies the signal distribution layer between the EREG (Exciter Regulator) controller board and the field terminal blocks. It receives setpoint and feedback signals from the EREG processor, conditions and distributes them to the AVR (Automatic Voltage Regulator) firing circuits, field current transducers, and protective relay interfaces. The board also aggregates status feedback — including field ground fault, overcurrent, and thermal alarm signals — and routes them back to the Mark VI I/O processor for supervisory control and SCADA integration.
Signal flow summary:
- EREG Controller → IS200ERSDG1A → AVR Firing Circuit
- Field Current Transducer → IS200ERSDG1A → EREG Feedback Loop
- Protective Relay Status → IS200ERSDG1A → Mark VI I/O Processor

Technical FAQ
Q: Is the IS200ERSDG1A compatible with both Mark VI and EX2100 systems?
A: Yes. The board is designed for use within GE’s EX2100 excitation control system, which is integrated with the Mark VI turbine control platform. It is compatible with both architectures as deployed in GE Frame turbine installations.
Q: Can this board be used as a direct replacement without reconfiguration?
A: In most standard configurations, yes — it is a plug-in replacement. However, we recommend consulting your GE Mark VI system documentation and verifying the revision suffix (G1A) matches your existing board before installation.
Q: Do you provide a test report with the board?
A: Yes. Every unit shipped from Konmask.com includes a functional test report and incoming inspection checklist.
Q: What is the lead time for bulk orders?
A: Standard stock ships within 3–5 business days. For bulk orders of 5+ units, please contact us for availability and lead time: support@konmask.com.
Q: Do you ship internationally?
A: Yes. We ship worldwide via DHL, FedEx, and SF Express. Export documentation (commercial invoice, packing list, HS code declaration) is provided for customs clearance.
