Product Description
The DS200TCCBG3BCB, a board component within GE’s Mark V turbine control system, functions as a Common Extended Analog I/O Board. This board provides conditioning and scaling for analog I/O signals from the TBCB board, another product available in our inventory of new and refurbished Mark V Series product offerings. This board is located in the <R5> core within its greater Mark V Series automated drive assembly. This DS200TCCBG3BCB board also reads signals from the TCEB board located in the <P1> core. The Mark V system is one of many Speedtronic turbine control systems created by General Electric for managing industrial gas and steam turbine systems, and exists as a legacy series given its eventual discontinuation in the years following its original conception. This DS200TCCBG3BCB product offering exists as a modified version of an original Mark V Series product offering; altering the DS200TCCBG3 PCB through its inclusion of a three-fold revision history including two functional product revisions and an artwork revision.
Hardware Tips and Specifications
The DS200TCCBG3BCB board can read generator and bus voltage inputs, line current inputs, RTDs, and 40-20 mA/0-1mA inputs. These signals come from a variety of connectors, including a specific set of connectors that are typically left unused, as vestigial structures in the assembly of this DS200TCCBG3BCB product. Some of the connectors useful to the DS200TCCBG3BCB board include:
- The 2PL TCPS Board Power Distribution Connector
- The 3PL COREBUS Conditioned Signals Connector
- The JHH TBCB Board RTD Input Signals Connector
- The JII TBCB Board Input Signals Connector
- The JMP TCEB Board PT and CT Signals Connector
- The JKK Connector
- The JTEST Connector
- The TCQPL Connector
All of these listed connectors in the assembly of this DS200TCCBG3BCB printed circuit board have been named through a combination of their factory-printed nomenclature labels, Mark V Series interfacing potentials, and their specific application to the DS200TCCBG3BCB Common Extended Analog I/O Board, spare the JKK, JTEST, and TCQPL Connectors, which have not been named as such due to their unused status during normative functioning of this DS200TCCBG3BCB product. Many of the jumpers available to the assembly of this DS200TCCBG3BCB PCB have been similarly-labeled with their own specific factory-printed nomeclatutes. Jumper switches (J1 through J5) control line current monitoring and generator/bus voltage monitoring functionality on the DS200TCCBG3BCB board. Jumpers are also used to connect an RS232 serial port to DCOM (J14) and for testing (J15 and J16.) General Electric manuals, including the one attached above, will provide additional information about jumper settings.
The DS200TCCBG3BCB board is a component dense board. The board includes an LED indicator that typically will only be noticed from a side view of the board. It also has multiple integrated circuits, including FPGAs or Field-Programmable Gate Arrays. The DS200TCCBG3BCB board uses resistors, resistor network arrays, capacitors, and diodes for basic voltage protection purposes. Most components on the board are marked with a reference designation or with an original manufacturer part number to help with identification, and corners of the board have been factory drilled to allow for mounting within the system.
