Product Description
This DS200TCEBG1ABC General Electric printed circuit board product offering was originally manufactured for the Mark V Turbine Control System Series, for a specific functional role as a Protective Termination Expander Board. The Mark V Series that this DS200TCEBG1ABC printed circuit board or PCB for short is a member of is considered a now-obsolete legacy General Electric product series, considering its eventual manufacturing discontinuation that took place in the many years since its initial release. This DS200TCEBG1ABC PCB's greater Mark V Turbine Control System Series has specific applications in the control and management systems of popular and compatible wind, steam, and gas turbine automated drive assemblies, and exists as one of the final General Electric Mark product series to incorporate their patented Speedtronic control system technology into its various offerings. While this DS200TCEBG1ABC product is definable as a Protective Termination Expander Board in its own right, the originally-introduced product of this functionality within the Mark V Series is the DS200TCEBG1 Protective Termination Expander Board missing all three of this DS200TCEBG1ABC PCB's three significant product revisions.
Hardware Tips and Specifications
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. This is but one of the many connectors defined in this DS200TCEBG1ABC product's original instructional manual materials. Each connector in the assembly of this DS200TCEBG1ABC product offering is accompanied by its own factory-printed nomenclature label, and interfaces to specific other Mark V Series devices. Some of the other connectors in this DS200TCEBG1ABC PCB's assembly include:
- The JKX/Y/Z TCEA Boards Various Signals Connectors
- The JMP TCCB Board PT and CT Signals Connector
- The JU PTBA Board Magnetic Pick Up and Flame Detection Signals Connector
- The JVA PTBA Board Flame Detection Signals Connector
- The JWX/Y/Z TCEB Board 335 V dc Signal Connector
Each connector available to the assembly of this DS200TCEBG1ABC product offering has been named through a combination of their Mark V Series interfacing potentials, their types of accepted or transmitted signals, and primarily by their factory-printed nomenclature label as mentioned above. After being written to the TCCB board located in the <R5> core, the signals can be used for embedded 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. Before making any singular final purchase decision on this DS200TCEBG1ABC product offering, it is of paramount importance to understand that its normal Mark V Series assembly has been altered from its originally-indicated performance specifications and basic dimensions through its acceptance of three significant product revisions, including two functional revisions and an artwork configuration revision.
