The GE DS200TBQAG1ABB is a high-density RST (Relay Signal Terminal) and thermocouple termination board designed for the GE Mark V Speedtronic turbine control system. It serves as a central signal hub, handling large volumes of thermocouple and control wiring between field instrumentation and turbine control processors.
Built for mission-critical energy systems, this module is widely used in gas, steam, and wind turbine control applications where precise temperature monitoring and stable signal routing are essential for safe and efficient operation.
