TCCA CONFIGURATION:

Hardware: There are three hardware jumpers - J1, JP2, and JP3 on the TCCA board. J1 is used to enable/disable the serial RS232 port. JP2 is used to disable the oscillator for the card test. JP3 is used for factory tests. Refer to Appendix A for information on the hardware jumper settings for this board.

Software: I/O configuration constants for the thermocouples, RTDs, mA inputs and outputs, and the shaft voltage and current settings are entered in the I/O Configuration Editor located on the HMI as described below.

A:The TCCA board is located inside the core of the turbine control cabinet. It works alongside terminal boards such as CTBA, TBQA, and TBCA, all of which are also housed in the core. Its strategic placement within this core allows it to effectively process various analog signals and serve as a central hub for analog input and output communications.

Q:What types of analog signals does the TCCA board support?

A:The TCCA board is capable of handling multiple types of analog signals. These include 4–20 mA inputs and outputs, which are commonly used for transmitting sensor data in industrial environments due to their resistance to electrical noise.

Q:How does the TCCA handle 4–20 mA signals?

A:The TCCA board reads 4–20 mA input signals through the JBB connector from the CTBA terminal board. The input current passes through a burden resistor on the board, creating a voltage drop, which is then measured and processed. This voltage is transmitted through the 3PL connector to the I/O engine.
