The GE IS200TBTCH1BCB is a thermocouple input terminal board designed for GE Mark VI turbine control systems. It receives temperature signals from field-mounted thermocouples and routes them to compatible I/O processing hardware for measurement and monitoring. The board supports temperature acquisition in turbine control applications.
