The IS200STTCH2A is a specialized Thermocouple Input Terminal Board utilized within the GE Speedtronic Mark VI turbine control system. This hardware component functions as the critical physical interface for receiving low-voltage signals from thermocouple sensors located throughout the turbine environment. It conditions these sensitive signals—such as those measuring exhaust gas temperature (EGT) or bearing temperatures—ensuring they are accurately digitized and processed by the Mark VI control system to facilitate precise thermal management and over-temperature protection.
