Description
The GE DS200TCQCG1B is an RST Overflow Board / Analog I/O Expander Board designed for the GE Speedtronic Mark V turbine control system. It provides analog signal expansion, processing, and routing functions within GE turbine control architectures used for gas, steam, and industrial turbine applications.
The DS200TCQCG1B belongs to the Mark V DS200 family and is used in RST (Redundant Simplex Triple) control configurations. The board supports analog I/O expansion functions and interfaces with turbine control processors through multiple high-density connectors, helping manage field signal transmission and control feedback.
This GE control board is commonly installed in turbine control cabinets for maintenance replacement, system restoration, and retrofit projects where original Mark V hardware must be maintained.
