Description

The IS200EISBH1AAC is an Exciter ISBus Board designed as part of GE’s Mark VI Speedtronic turbine control system. This board serves as a key interface between the exciter and fiber-optic-based voltage and current feedback signals, facilitating accurate communication and monitoring within the turbine’s excitation control loop.

The front faceplate features:

• Two locking set pins to secure the board into a VME rack

• Fiber optic ports labeled:

• Gen Field Voltage and Current

• Exciter Voltage and Current

• Ground Detect In / Out

• A reset switch accessible through an opening in the faceplate

• GE logo and board identification markings

The faceplate is fastened to the board using screws, and the board itself contains:

• Over 20 integrated circuits

• A single backplane connector for input/output of fiber optic signals

• Two small transformers

• Multiple inductors, capacitors, resistors, transistors, and diodes

• Conformal PCB coating for protection in industrial environments

• Factory-drilled mounting holes and barcode labels for traceability

Product Code Interpretation

The part number IS200EISBH1AAC contains structured identifiers:

• IS200: Standard Mark VI Series assembly; manufactured by GE

• EISB: Denotes the board’s function as an Exciter ISBus interface

• H1: Indicates a conformal-coated version

• AAC: Denotes the specific revision level (three total revisions, backwards-compatible with the first two)

Technical Highlights

• Designed for interfacing fiber-optic signals in generator excitation systems

• Provides electrical isolation and signal processing

• Built for durability in high-temperature, high-vibration environments

• Conformal coating enhances resistance to moisture, dust, and contaminants
