Product Overview:

The DS200TCQCG1BHF is an Analog I/O Expander Board, commonly referred to as an RST Overflow Board, developed by General Electric for use in the Mark V Speedtronic control system. It is primarily installed in EX2000 exciter systems and medium- to large-frame heavy-duty gas turbines, as well as aero-derivative turbines.

As part of GE’s Mark V system, this board operates within a triple-redundant R/S/T processor architecture, which provides high-reliability and fault-tolerant control for critical turbine operations.

Functionality:

• Functions as an Analog I/O Expander Board within the Mark V system

• Provides excitation to LVDT (Linear Variable Differential Transformer) and LVDR (Resolver) sensors

• Supports overflow handling in RST cores to manage additional signal processing

Hardware Features:

The DS200TCQCG1BHF is densely populated with high-performance components and connection ports to ensure seamless integration and operation within the turbine control system:

Connectors:

• 11 vertical pin cable connectors

• 5 male vertical pin header connectors

• 1 vertical female plug connector

Additional Components:

• 6 relay components

• Over 25 resistor network arrays

• 40+ integrated circuits (ICs)

• 37 jumper switches – must be set to match previous configuration

• Heat sink for thermal management

• Various passive and active components:

• Transistors

• Ceramic capacitors

• Diodes

• Metal film resistors

• Other capacitive/resistive materials

Physical Characteristics:

• Drilled mounting holes in all four corners

• Labeled edges for orientation and alignment

• Markings: Includes identifiers such as C-ESS and 6BA04

Application Context:

• Designed for Mark V EX2000 excitation systems

• Compatible with single or dual gas turbines and aero-derivative models

• Performs critical analog signal expansion for real-time control and monitoring

• Operates in systems where triple modular redundancy (TMR) is essential for safety and reliability

Important Considerations:

• The DS200TCQCG1BHF is a revised version of the base DS200TCQCG1 model

• Ensure jumper settings match those of the board being replaced

• Maintain proper clearance for heat sink ventilation

• Refer to original GE manuals or datasheets for wiring, signal references, and technical specifications

• While technical support is provided by GE, resellers typically do not offer deep-level technical support for configuration

Conclusion:

The GE DS200TCQCG1BHF is a robust and specialized Analog I/O Expander Board, essential for Mark V systems requiring excitation control, analog signal overflow handling, and system redundancy. Its advanced hardware and compatibility with EX2000 and turbine systems make it a vital component in turbine control architectures.
