The DS200TCEBG1ABC is a Protection Termination Expander board for the Mark V series from GE. The Mark V is part of the successful Speedtronic line of gas/steam management systems for heavy-duty turbines that began with the release of the Mark I in the 1960s. These systems have decades of research and development behind them and use the most up-to-date technology available at the time of their release to create management systems that will provide the most reliable management for heavy-duty gas and steam turbines.
The DS200TCEBG1ABC is located in the <P1> core and is designed to scale the CT and PT signals used by the TCCB board in the <R5> core of the Mark V system. Signals for emergency flame detection and overspeed also pass through the TCEB board from the PTBA board where they are detected by the TCEA board for processing. The alarm horn for the MKV LM is located on the TCEB board. This board has no software configuration.
The DS200TCEBG1ABC has thirteen I/O board connectors located on its surface. These connections are labeled with designators that start with “J.” The uses of these connectors can be found in the Speedtronic Mark V LM Turbine Control Manual (GEH-6153.) If this manual has not been retained, please let your salesperson know at the time of purchase of your part.
The DS200TCEBG1ABC is built with four potentiometers, four transformers, three inductor coils, eight polyester vinyl capacitors, twenty resistors including one CCR that is mounted above the board, three diodes, and the connectors/alarm mentioned earlier. Please review safety procedures before beginning your installation.
