Functional Description

DS200TCCBG3BCC is a Common Extended Analog I/O Board developed by GE. It is a part of the Mark V control system. The Common Extended Analog I/O Board (TCCB) scales and conditions a variety of analog input signals sourced from the TBCB terminal Board located on the R5 core and the TCEB board in the P1 core. Once scaled and conditioned, these analog signals are transmitted to the STCA board via the 3PL connector. The STCA board serves as a central receiver for these signals, where they are further utilized for operational control, monitoring, and data logging purposes. This integration ensures that the system can effectively manage and respond to real-time operational conditions based on accurate and reliable analog measurements.

Features

• Analog Inputs: TCCB processes signals such as 4-20 mA and 0-1 mA inputs, which are commonly used for measuring parameters like fluid flow rates, pressure, or other process variables. These inputs provide essential data for operational monitoring and performance assessment.
• RTDs (Resistance Temperature Detectors): Signals from RTDs, used for temperature measurement, are also scaled and conditioned by TCCB. This ensures accurate temperature readings, crucial for maintaining optimal operating conditions and ensuring equipment longevity.
• Generator and Bus Voltage Inputs: Voltage inputs from generators and buses are another critical aspect handled by TCCB. These inputs help monitor the electrical output and stability of generators and buses, contributing to overall system reliability and efficiency.
• Line Current Inputs: TCCB processes inputs related to line currents, which are vital for monitoring power consumption, load balancing, and ensuring electrical system integrity.

RTD (Resistance Temperature Detector) circuitry

The TCCB board hosts the circuitry responsible for providing excitation to the RTDs, which are connected via the TBCB terminal board. RTDs operate by varying their resistance with changes in temperature. A constant current is applied through the RTD from the TBCB terminal board. As the temperature changes, the resistance of the RTD adjusts accordingly, causing a corresponding change in voltage across the RTD.

• The TCCB board performs several essential functions with respect to RTD signals: Measurement and Conditioning: The TCCB board measures the voltage across the RTD and scales it according to predefined parameters. This scaling ensures that the measured voltage accurately represents the temperature detected by the RTD. Additionally, the board conditions the signal to filter out noise and ensure signal integrity, crucial for precise temperature readings.
• Signal Transmission: RTD signals are transmitted from the TBCB terminal board to the TCCB board via the JCC and JDD connectors. These connectors facilitate the transfer of analog signals, ensuring that the temperature data from RTDs is reliably received and processed by the TCCB board.
• Integration with I/O Engine: Once processed and conditioned, the RTD signals are sent to the I/O Engine via the 3PL connector. The I/O Engine serves as a central hub for receiving and managing analog inputs across the system. This integration allows for real-time monitoring of temperature variations, essential for maintaining operational parameters within desired limits.
• RTD Type Selection: The type of RTD used (such as platinum, nickel, or copper) is configured using I/O configuration constants. These constants define the specific characteristics of the RTD, including its resistance-temperature relationship and calibration parameters. This ensures accurate measurement and compatibility with the system's operational requirements.
