DS200TCCBG3BCB

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.  This board is located in the <R5> core.  It 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. 

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 the 2PL, 3PL, JHH, JII, and JMP.  The board has three additional connectors that are typically left unused. 

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 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. The board uses resistors, resistor network arrays, capacitors, and diodes.  Most components on the board are marked with a reference designation or with an original manufacturer part number to help with identification.  Corners of the board have been factory drilled to allow for mounting within the system.
