About the IS200EISBH1AAB

The IS200EISBH1AAB circuit board is part of the Mark VI Speedtronic system—a gas and steam turbine management platform developed and originally distributed by General Electric. The Speedtronic systems have been evolving since the late 1960s. The Mark VI version enhances functionality by integrating Ethernet capabilities and offering configurations such as Simplex or Triple Modular Redundant (TMR) systems to suit the size and complexity of turbine control needs.

This Exciter ISBus Board belongs to the Mark VI Turbine Control System Series, which supports control and management of GE-compatible gas, steam, and wind turbine automated drive assemblies. The Mark VI series is a significant advancement over the preceding Mark V series, adding support for alternative energy applications such as wind turbines in addition to traditional gas and steam turbines.

Hardware Overview and Specifications

• The IS200EISBH1AAB serves as an Exciter ISBus board within the EX2100 excitation control system.

• Typically installed in 13- or 21-slot VME card rack control modules.

• Communicates with the Mark VI PC-based Human Machine Interface (HMI), centralizing access to analog and digital data with high-resolution time tags for alarms and events.

• Manages all fiber-optic communications within the cabinet.

• Supports fiber-optic feedback signals transmitted via the backplane connector.

• Accepts voltage and current signals through six fiber-optic connectors located on the front faceplate, labeled as:

• Gen Field

• Exciter (for both voltage and current)

• Gnd Detect

• The front faceplate features the board ID number, GE logo, and access openings for a reset switch.

• Key board components include transformers, transistors, and integrated circuits.

• The board is marked with codes such as 6DA00 and 6BA00.
