Description
🔹 Product Description
The GE DS200TCQCG1A, also identified as DS200TCQCG1AHE, is an RST Overflow Board and Analog I/O Expander Board for the GE Mark V Speedtronic turbine control system. The TCQC board expands the analog I/O capability of the R, S, and T control cores and provides signal scaling and conditioning for additional turbine feedback signals. It supports mA current-loop and pulse-rate signal processing, LVDT/LVDR excitation, generator and line feedback interfaces, and related Mark V I/O functions. The board includes multiple high-density connectors and 24 configuration jumpers for application-specific hardware configuration. The supplied condition is New – Open Box.
