FUNCTIONAL DESCRIPTION:

DS200TCQCG1AGD is an Analog Input/Output Expander Board manufactured and designed by General Electric as part of the Mark V LM Series used in the Line of Microprocessor aero-derivative turbine Control Systems. The Analog IO Expander board (TCQC) provides scaling and conditioning for additional analog signals read from the terminal boards of the I/O cores. The TCQC board provides LVDT and LVDR excitation. The IONET termination for and is on the TCQC board in the core. If the optional <21> is installed, that IONET termination is on the TCQC in . The mA input for the megawatt transducer signal is scaled and conditioned on the TCQC board and written to the STCA board via the 19PL connector. Pulse rate inputs are scaled and conditioned on the TCQC board. In most applications, the high-pressure shaft speed signals and occasionally the liquid fuel flow signals are scaled on the TCQC board and written to the TCQA board via the JE connector in the core. The TCQC board communicates the generator and line signals with the STCA board via the JE connector.

TCQC CONFIGURATION:

Hardware: The first 16 hardware jumpers on the TCQC board configure the output current range for the servo outputs. The even-numbered jumpers select the feedback scaling, while the odd-numbered jumpers select the source output resistance. Hardware jumpers 25 through 36 are for added feedback scaling options for servos one through four, giving them a maximum current range of +/- 240 mA. BJ17 sets the RS232 port for card tests. BJ21 is the stall timer enabled. BJ22 is the oscillator enabled for factory tests. BJ23 and BJ24 are not used. BJ18 and BJ20 limit the P15 and N15 supply to the proximity transducers. Hardware jumpers JP38 and JP39 set the magnetic pickup gain for liquid fuel flow signals in some applications. Refer to Appendix A and the paragraphs below for information on the hardware jumper settings for this board.

TCQC PULSE RATE INPUT CIRCUIT:

The high-pressure shaft pulse rate signals are read from the TCQE board via the JJ connector. The TCQE board signals originate on the PTBA board in the core. The high-pressure shaft signals are written to the TCQA board via the JE connector to be scaled and conditioned and then are written to the STCA board via 3PL. The pulse rate inputs from both the magnetic speed sensors and the TTL-type sensors that landed on the TBQB terminal board pass through the TCQC board via the JH connector. Additional magnetic pickup pulse rate signals are available on the QTBA board and are read by the JGG connector. Some of the signals landed on the PTBA terminal board could be landed on the QTBA terminal board and should not be used on both. The corresponding screws on the QTBA terminal board are not available if the signals are also landed on the PTBA terminal board.

FREQUENTLY ASKED QUESTIONS:

What is an Analog Input/Output Expander Board?

An Analog Input/Output Expander Board is a device that increases the number of analog input and output channels available to a microcontroller or other computing system. It allows for more sensors and actuators to be connected and controlled.

How does the expander board connect to my microcontroller?

The expander board typically connects to your microcontroller via communication protocols such as I2C, SPI, or UART. Detailed instructions on connections are usually provided in the board's datasheet or user manual.

What types of analog signals can the expander board handle?

Most expander boards can handle standard analog signals ranging from 0 to 5V or 0 to 3.3V, depending on the specifications of the board. Check the datasheet for exact voltage ranges.
