Functional Description

DS200TCCAG1D is a Common Analog I/O Board developed by GE. It is a part of the Mark V control system. The Common Analog I/O Board (TCCA) is a component within the R5 control system. It conditions and scales analog signals from various input and output sources connected to different terminal boards. These signals are then transmitted to other parts of the system for further processing and monitoring. Specifically, the TCCA board is responsible for handling a variety of analog signal types.

Functions of the TCCA Board

• Signal Conditioning: The board scales and conditions various types of analog signals, such as 4-20 mA inputs and outputs, RTD signals, thermocouple signals, shaft voltage and shaft current inputs. Signal conditioning ensures that raw data received from sensors and measuring devices are appropriately adjusted for further processing.
• Signal Processing: The conditioned signals are then sent to the STCA board for further processing via the 3PL connector. This enables the system to maintain accurate control and monitoring of critical variables such as temperature, voltage, and shaft conditions in the machinery or system.
• Versatility: The board is capable of handling various signal types from different terminal boards (CTBA, TBQA, TBCA), allowing for flexible integration in different setups across the control system. It is designed to support multiple industrial applications where monitoring and regulation of analog inputs and outputs are necessary.

Connectors

• 2PL (Power Distribution): This connector distributes power from the TCPS board in the R5 core to the TCCA board, ensuring the board operates correctly by providing the necessary power.
• 3PL (Data Bus): The 3PL connector serves as the data bus between multiple boards: STCA, TCCA, and TCCB in the R5 core. It transmits the conditioned analog signals across the system, allowing them to be integrated into the COREBUS for overall system management and monitoring. This connector is crucial for efficient data transfer between the system’s control components.
• JAA (4-20 mA Output): The JAA connector carries the 4-20 mA output signals to the CTBA terminal board. These output signals are vital for controlling various process variables, such as temperature and pressure, in industrial equipment.
• JBB (Shaft Voltage/Current and  4-20 mA Input): This connector handles shaft voltage and shaft current signals, which are essential for monitoring the mechanical health of rotating machinery. It also carries 4-20 mA input signals from the CTBA terminal board, enabling the system to monitor and control these values effectively.
• JCC/JDD (RTD Input Signals): These connectors carry RTD input signals from the TBCA terminal board. RTDs (Resistance Temperature Detectors) are used to measure temperature with high precision. The JCC and JDD connectors allow the system to collect accurate temperature data for control and monitoring.
• JAR/S/T (Thermocouple & Cold Junction Inputs): The JAR/S/T connector transmits thermocouple input signals and cold junction inputs from the TBQA terminal board. Thermocouples are commonly used to measure high temperatures, and the cold junction input helps compensate for temperature changes at the junction, ensuring accurate temperature readings.
• JC (Power Supply Diagnostic Signals): The JC connector carries power supply diagnostic signals from the TCPS board. These diagnostic signals are crucial for monitoring the health and stability of the power supply, ensuring that the system operates efficiently and without interruptions.
• JEE (Unused): The JEE connector is typically not used but is available for future expansion or additional functionality if required by the system.

Hardware Configuration

• J1 (RS232 Port Enable/Disable): This jumper is used to enable or disable the serial RS232 port, allowing for communication between the TCCA board and external devices or systems through serial connections.
• JP2 (Oscillator Disable for Card Testing): This jumper disables the oscillator on the board, which is useful during card testing. Disabling the oscillator ensures that the board’s functionality can be tested without interference from oscillation signals.
• JP3 (Factory Test): The JP3 jumper is reserved for factory testing and should only be used during manufacturing or diagnostic procedures to verify the board’s integrity and operation.

Software Configuration

• The I/O Configuration Editor on the HMI (Human Machine Interface) is used to enter various configuration constants for the analog inputs and outputs, such as Thermocouples, RTDs, 4-20 mA inputs and outputs, Shaft voltage and current settings.
• These settings are necessary to ensure the proper operation of the system by defining the correct parameters for each input and output. Operators can configure the system’s behavior based on the specific requirements of their application.
• The I/O Configuration Editor allows users to set up the board to read and process the appropriate signals from the terminal boards, and it provides the ability to adjust settings based on operational needs.
