Functional Description

DS215TCCBG8BZZ01A is a common extended analog I/O board developed by GE. It is a part of GE drive control system. The Common Extended Analog I/O Board scales and conditions additional analog I/O signals read from the R5 core's TBCB terminal board and the P1 core's TCEB board. 4.20 mA/0.1 mA inputs, RTDs, generator and bus voltage inputs, and line current inputs are among the signals. The scaled and conditioned signals are received by the board via the 3PL connector.


  • 2PL - Power distribution from the TCPS board in the R5 core.
  • 3PL - The Data Bus in core R5 that connects the STCA, TCCA, and TCCB boards.
  • Conditioned signals are transferred to the COREBUS via 3PL.
  • JHH - Transports the TBCB terminal board's 4.20 mA/0.1 mA input signals.
  • The RTD input signals from the TBCB terminal board are carried by JII.
  • JMP - In the P1 core, it transports potential and current transformer (PT and CT) signals from the TCEB board.
  • JKK - Not commonly used.
  • JTEST - Not commonly used.
  • TCQPL - Not commonly used.

Hardware Configuration

  • In the Mark V LM, the hardware jumpers J1, J2, J3, J4, and J5 are used to provide the generator and bus voltage monitoring functions, as well as the line current monitoring function.
  • J14 is a hardware jumper that connects the RS232 serial port to DCOM. J15 and J16 are hardware jumpers used for testing. 

Software Configuration

  • The I/O Configuration Editor on the HMI is used to enter I/O configuration constants for the RTDs, mA inputs, generator, and bus voltage and line current settings.

RTD Circuit

  • The TCCB board contains the circuitry that supplies excitation to the RTDs from the TBCB terminal board. A constant current is passed through the RTD, and as the temperature changes, so does the resistance, causing the voltage on the RTD to change.
  • The voltages are measured, scaled, and condition by the TCCB board. The TCCB board reads the RTD signals from the TBCB terminal board via the JCC and JDD connectors.
  • The signals are sent to the I/O Engine by the TCCB board via the 3PL connector. I/O configuration constants are used to select the type of RTD.

Generator/Bus Voltageand Current Input Circuits

  • On the board, the voltage signals from the generator and bus, as well as the current signals from the line (PT and CT), are scaled and conditioned.
  • These signals are used to define phase currents and voltages, as well as to calculate generator megawatts, power factors, and VARs for power system monitoring.
  • These signals are read from the PTBA terminal board, scaled in the P core, and written to the board via the JMP connector.
