GE IS200ERRRH1A Exciter Regulator Redundant Relay Board
Product Brief Description
GE IS200ERRRH1A is a redundant relay board for the EX2100 excitation system under Speedtronic Mark VI turbine control platform. It is responsible for the switching logic between primary and backup excitation regulators, enabling bumpless transfer of excitation control to avoid generator excitation loss when the main regulator fails. It adopts conformal coating design and VME slot form for installation inside the exciter cabinet.

Product Functions
- Implement switching logic for dual redundant excitation regulators of EX2100 system
- Control relay circuits to realize bumpless switch between master and standby regulator
- Monitor status signals of excitation regulator channels and judge fault conditions
- Isolate fault excitation channel and lock switching signals to prevent misoperation
- Route control and feedback signals between regulator boards and power stage
- Conformal coated PCB for anti-moisture, dust and corrosion in power plant environment
- Standard VME rack mounting, compatible with Mark VI system backplane
Application Scenarios
- Gas turbine, steam turbine and hydro turbine generator excitation control systems
- Power plant EX2100 excitation cabinet spare replacement and maintenance
- Utility power generation stations and independent power producer facilities
- Oil & gas, chemical and metallurgy captive power plants
- Mark VI Speedtronic control system upgrade and retrofit projects
FAQ
Q1: Which system does IS200ERRRH1A belong to?
A1: It is designed for GE EX2100 excitation system and works with Speedtronic Mark VI turbine control platform.
Q2: What is the core purpose of this board?
A2: It controls the redundant relay switching logic to achieve seamless transfer between main and backup excitation regulators.
Q3: Can it work alone without other EX2100 regulator boards?
A3: No. It must cooperate with excitation regulator boards and related power modules of the EX2100 system.
Q4: What does conformal coating mean for this board?
A4: The PCB is covered with protective coating to resist humidity, dust and corrosive gas in power plant environment.
Q5: Will switching cause generator voltage fluctuation?
A5: It supports bumpless transfer under normal condition, which minimizes voltage disturbance during regulator switching.
