GE DS200TCCAG2B I/O TC2000 Analog Board

Part Number ds200tccag2b Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockS200TCCAG2B is a Common Analog I/O Board manufactured by General Electric as part of the Mark V Series used in gas turbine control management systems. The Common Analog I/O Board (TCCA), which is situated there, receives analog signals from the CTBA, TBQA, and TBCA terminal boards installed in the "R5" core. Some of the signals in this group are 420 mA inputs and outputs, RTD inputs, thermocouple inputs, shaft voltage inputs, and shaft current inputs. The signals are written to the STCA board through the 3PL connector. TCCA CONNECTORS: 2PL - The R5 core receives power from the TCPS board. 3PL - TCCA, STCA, and core 5 TCCB boards are connected by a data bus. For the transfer to the COREBUS, conditional signals are carried on 3PL. JAA - Contains the 4-20 mA output signals for the CTBA terminal board. JBB - Contains input signals from the CTBA terminal board, including the 4-20 mA input signals and shaft voltage and current signals. JCC - RTD input signals from the TBCA terminal board are present. JDD - Possesses RTD input signals from the TBCA terminal board. JAR/S/T - Contains cold junction inputs from the TBQA terminal board as well as thermocouple input signals. JC - Power supply diagnostic signals from TCPS are present.

JEE - It is not used CONFIGURATION: Hardware: There are three hardware jumpers with the designations J1, JP2, and JP3 on the TCCA board. Using J1, the serial RS232 port can be turned on or off. Using JP2, the oscillator is disabled for card testing. JP3 is used for testing in manufacturing. Appendix A contains details on this board's hardware jumper configurations. Software: The I/O configuration constants for the thermocouples, RTDs, mA inputs, and outputs, as well as the values for the shaft voltage and current, are entered in the I/O Configuration Editor, which is found on the HMI. TCCA 4 - 20 mA Input Circuit: The TCCA board provides the circuitry for the 420 mA input signals. The CTBA terminal board's signals are read using the JBB connector. The TCCA board measures the voltage drop across the burden resistor brought on by the transducer current and writes the results to the I/O Engine through the 3PL connector. TCCA 4-20 mA Output Circuit: The TCCA board's circuitry sends 420 mA outputs to the CTBA terminal board through the JAA connector. These transmissions are typically used to power distant monitoring devices. TCCA RTD CIRCUIT: The circuitry for the TBCA terminal board, which stimulates the RTDs, is located on the TCCA board.

A steady current is fed into the RTD, and when the temperature changes, the resistance shifts, changing the voltage on the RTD. The TCCA board calibrates, measures, and scales the voltage signal. The TCCA board reads the RTD signals from the TBCA terminal board via the JCC and JDD connectors. The signals from the TCCA board are sent to the I/O Engine using the 3PL connector. Constants in the I/O configuration are used to choose the RTD type. THERMOCOUPLE CIRCUIT: The thermocouple inputs are read by the TBQA terminal board. The TBQA terminal board's cold junction circuitry generates the cold junction signals. These variables are used by the TCCA board to calculate the cold junction correction. The TCCA board uses the thermocouple input and compensation value to calculate the actual temperature that the thermocouple reads. The I/O Engine reads the value through the 3PL connector. The types and curves of thermocouples are chosen based on the I/O configuration constants. SHAFT MONITORING: The voltage and current monitoring for the turbine shaft is controlled by the TCCA board. These signals are read from the CTBA terminal board through the JBB connector. The signals are written to the I/O Engine using the 3PL connection.

The R5 core location 2 houses the TCCA board. The Turbine Control R5> Micro Application Board A is what it is called. The following operations are defined by the TCCA configuration: RTD inputs and Thermocouple inputs Inputs in milliamps Monitoring shaft voltage and current DS200TCCAG1A INSTALLATION: The environment needed for proper cooling is created when the drive is installed. The drive needs to be mounted in a spot that is cool, clean, and free of dirt. Heat-producing equipment cannot be positioned on the wall opposite the drive if it is mounted there. In some places, fans could be necessary to ensure sufficient ventilation. If that's the case, make sure the fans are working properly once more. Make sure the drive is put in a location where there is enough space on all sides for air to circulate freely. The drive is set up so that air enters at the bottom and exits at the top as warm air. As it passes over the hot components, it heats up. Air travels over the components because of the cable routing. Ensures that cable bundles do not obstruct air movement or block air vents.
