FUNCTIONAL DESCRIPTION:

DS200TCCAG1ACA is a Common Analog I/O Board manufactured and Designed by General Electric as part of the Mark V Series used in gas turbine control systems. The Common Analog I/O Board (TCCA), located in the core, scales and conditions analog signals from the CTBA, TBQA, and TBCA terminal boards mounted in the core. These signals include 4-20 mA inputs and outputs, RTD inputs, thermocouple inputs, shaft voltage inputs, and shaft current inputs. The signals are written to the STCA board via the 3PL connector.

TCCA CONNECTORS:

  • 2PL - Power distribution from the TCPS board in the R5 core.
  • 3PL - The Data Bus between the TCCA, STCA, and core 5 TCCB boards. Conditioned signals are carried on 3PL for transferring to the COREBUS.
  • JAA - Possesses the 4-20 mA output signals to the CTBA terminal board.
  • JBB - Possesses the shaft voltage and current signals and 4-20 mA input signals from the CTBA terminal board.
  • JCC - Possesses RTD input signals from the TBCA terminal board.
  • JDD - Possesses RTD input signals from the TBCA terminal board.
  • JAR/S/T - Possesses Thermocouple input signals and cold junction inputs from the TBQA terminal board.
  • JC - Possesses Power supply diagnostic signals from TCPS.

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.

TCCA 4 - 20 mA INPUT CIRCUIT:

The TCCA board provides the circuitry for the 4-20 mA input signals. The signals are read from the CTBA terminal board via the JBB connector. The transducer current is dropped across a burden resistor and the voltage drop is read by the TCCA board and written to the I/O Engine via the 3PL connector.

TCCA 4 - 20 mA INPUT CIRCUIT:

The TCCA board provides the circuitry for driving 4-20 mA outputs to the CTBA terminal board via the JAA connector. These signals are typically used to drive remote instrumentation for monitoring.

SHAFT MONITORING:

The TCCA board manages the voltage and current monitoring for the turbine shaft. Through the JBB connector, these signals are read from the CTBA terminal board. The 3PL connector is used to write the signals to the I/O Engine. 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

FREQUENTLY ASKED QUESTIONS:

What is the function of a Common Analog I/O Board?

A Common Analog I/O Board serves as an interface between analog signals from sensors or devices and digital systems like controllers or computers. It enables the system to read analog inputs (such as voltage or current from sensors) and output analog signals (like controlling actuators). These boards are essential for applications in industrial automation, process control, and data acquisition.

What types of signals can the board handle?

The board is designed to handle both voltage and current signals. Typically, it supports voltage ranges like 0-10V, ±10V, and current signals such as 4-20 mA. This versatility makes it compatible with a wide variety of industrial sensors and actuators.

How many input and output channels does the board have?

The number of channels varies depending on the model. For example, a standard board might have 8 analog input channels and 4 analog output channels. These channels can operate independently and often include configurable settings to accommodate different signal types.
