SPECIFICATIONS

Part No.: DS200TCCAG2BAA
Manufacturer: General Electric
Country of Manufacture: United States of America (USA)
Product Type: Analog I/O Board
Availability: In Stock
Series: Mark V

Functional Description

DS200TCCAG2BAA is an Analog I/O Board developed by GE. It is a part of Mark V control system. It processes 4-20 mA inputs and outputs, RTD inputs, thermocouple inputs, shaft voltage inputs, and shaft current inputs, ensuring accurate data transmission to the control system. The board receives signals from CTBA, TBQA, and TBCA terminal boards and transmits them to the STCA board via the 3PL connector. It features three hardware jumpers J1 for enabling/disabling the RS232 serial port, JP2 for disabling the oscillator for card testing, and JP3 for factory testing. The software configuration is managed through the I/O Configuration Editor on the HMI, allowing adjustments for thermocouples, RTDs, current loops, and shaft monitoring settings. This board plays a crucial role in ensuring precise signal processing and reliable operation in turbine and industrial control applications.

Analog Signal Processing

The Common Analog I/O Board (TCCA) is housed in the R5 core of the Mark V control system. It is responsible for scaling and conditioning various analog signals that originate from the following terminal boards:

• CTBA (Current Terminal Board A)
• TBQA (Terminal Board for RTDs & Thermocouples)
• TBCA (Terminal Board for Shaft Voltage & Current Inputs)

The TCCA board processes different types of analog inputs and outputs, including:

• 4-20 mA current loop signals for industrial process control
• RTD (Resistance Temperature Detector) inputs for temperature monitoring
• Thermocouple inputs for accurate temperature sensing
• Shaft voltage inputs to detect electrical imbalances in rotating machinery
• Shaft current inputs to monitor grounding and insulation conditions

Once conditioned, these signals are transferred to the STCA board via the 3PL connector for further processing, analysis, and control actions.

Hardware Configuration

The board is equipped with three hardware jumpers that allow configuration and testing adjustments:

• J1: Enables or disables the RS232 serial port, which is used for communication and diagnostics.
• JP2: Disables the oscillator for card testing purposes. This setting is typically used during maintenance or troubleshooting.
• JP3: Reserved for factory testing to ensure quality control before deployment.

These hardware jumpers provide flexibility in configuring the board, allowing it to be adapted to different operating conditions and system requirements.

Software Configuration

The I/O configuration settings of the board are managed through the I/O Configuration Editor on the HMI (Human-Machine Interface). This allows for easy customization of the board’s operation based on system needs. The configurable parameters include:

• Thermocouple settings for accurate temperature measurements
• RTD configuration to optimize resistance-based temperature readings
• Current loop (mA) input and output adjustments for process control applications
• Shaft voltage and current calibration to ensure proper monitoring of rotating machinery

This software-based configuration enhances flexibility, enabling engineers to fine-tune the board’s performance without requiring extensive hardware modifications.
