GE DS200TCOAGIBDC Thermocouple Input/Output Module(XIONGBA)

Product Overview
The GE DS200TCOAGIBDC is a Thermocouple Input/Output Module designed for GE’s Mark V Speedtronic Turbine Control System, a legacy platform widely used in gas and steam turbine automation. This board plays a critical role in conditioning thermocouple signals for temperature monitoring and control in turbine systems, ensuring precise operation and safety. It interfaces with thermocouple sensors (e.g., Type J, K, T) and provides cold-junction compensation to eliminate errors caused by ambient temperature fluctuations .

Engineered for rugged industrial environments, the DS200TCOAGIBDC features advanced signal conditioning circuitry and modular connectivity. Its design allows seamless integration into Mark V cabinets, ensuring compatibility with terminal boards (e.g., TB QA, TB QC) and other modules like the DS200TCQAG1BHF analog I/O board . With diagnostic LED indicators and field-replaceable components, this board supports real-time status monitoring and maintenance, making it ideal for power generation, oil and gas, and heavy industry applications.
