Product Description
Produced by General Electric for the Mark V series, GE's DS200TCEBG1ABC functions as a Protection Termination Expander board. It is located in the <P1> core of the Mark V and is designed to scale the CT and PT signals employed by the TCCB board in the <R5> core of the Mark V system. The CT and PT signals that are scaled by the TCEB are then used for line current, generator voltages, and bus voltages. Signals related to emergency overspeed and flame detection also travel through the TCEB board from the PTBA board. This is followed up by the TCEA board detecting these signals for conditioning. The 335 V DC required for flame detector units also travels across the TCEB and is processed before being forwarded to the PTBA terminal board.
The JV connector from the PTBA terminal board allows the CT and PT signals to be read and stepped down. After being written to the TCCB board located in the <R5> core, the signals can be used for imbedded functions. The board has no software configuration. There are also no hardware jumpers on the TCEB board. While the alarm horn for the MKV LM is located on the TCEB board, the alarm horn jumper is located instead on the PTBA terminal board.
