Functional Description

DS200TCCBG2A is a Common Extended Analog IO Board developed by GE. It is a part of Mark V control system. It plays a role in expanding the system's analog input and output capabilities, enabling high-accuracy monitoring and control of a wide range of analog signals essential for turbine and generator performance.

Features

The TCCB board is primarily responsible for scaling, signal conditioning, and interfacing with additional analog I/O signals. These signals are sourced from other terminal boards such as the TBCB (located in the R5 core) and the TCEB (located in the P1 core). Once processed, these conditioned analog signals are relayed to the STCA board through the 3PL connector for integration into the main control and monitoring processes.

The types of analog signals processed by the TCCB board include:

• 4–20 mA / 0–1 mA current loop signals
• RTD (Resistance Temperature Detector) signals
• Generator voltage and bus voltage inputs
• Line current transformer (CT) signals

This expanded input handling is essential in applications where precise monitoring of temperature, current, and voltage is required for effective control and protection of turbine-generator systems.

TCCB Board Connectors and Signal Paths

• 2PL Connector: Supplies power to the TCCB board. This power is distributed from the TCPS power supply board located in the R5 core.
• 3PL Connector: Acts as the data communication bus among the STCA, TCCA, and TCCB boards within the R5 core. It transmits the conditioned analog signals to the COREBUS for use by the control logic and monitoring systems.
• JHH Connector: Receives 4–20 mA or 0–1 mA input signals from the TBCB terminal board. These signals typically originate from transmitters and analog sensors installed in the field.
• JII Connector: Handles RTD input signals from the TBCB board, used for temperature measurement across various equipment components.
• JMP Connector: Accepts Potential Transformer (PT) and Current Transformer (CT) signals from the TCEB board located in the P1 core. These signals provide key voltage and current readings required for generator protection and monitoring.
• JKK, JTEST, and TCQPL Connectors: These connectors are typically unused in standard configurations but may serve specific diagnostic or expansion purposes depending on system design.

TCCB Hardware Configuration

• Jumpers J1 through J5: These are used to enable and configure monitoring functions for generator and bus voltages, as well as line current measurements in the Mark V LM (Load Management) application.
• Jumper J14: Connects the board’s RS232 serial communication port to DCOM (Data Communications) for diagnostics and data transfer.
• Jumpers J15 and J16: Reserved for testing purposes. These are not typically used during normal operation but may be engaged during diagnostics or factory configuration.

TCCB Software Configuration

• Input types and ranges for RTDs and mA signals
• Scaling and alarm limits for voltage and current inputs
• Mapping of signals to specific functions within the control system

Proper configuration ensures that the analog inputs are accurately interpreted and used by the control system for real-time monitoring, protection, and turbine performance optimization.
