The IS200VTCCH1CBB is a Turbine Control Channel Board from GE's Mark VIe series, primarily used in control systems for large rotating machinery such as gas turbines and steam turbines. It handles critical control signal processing and channel management functions. Below is its detailed information:
- Module Type: Turbine control channel board, one of the core I/O modules in the Mark VIe control system.
- Primary Function: Processes key sensor signals of turbines (e.g., speed, pressure, temperature), executes control algorithms, and conditions feedback signals.
- Signal Processing Capability: Supports multiple analog and digital input/output signals, including thermocouples, RTDs (Resistance Temperature Detectors), and 4-20mA analog signals, adapting to industrial-grade sensor interfaces.
- Communication Interface: Communicates with CPU modules and other I/O modules via the backplane bus of the Mark VIe system, ensuring real-time data transmission and control command response.
- Power Requirement: Typically powered by a system power module with DC voltage (typically 24VDC); specific parameters must comply with Mark VIe system power specifications.
- Operating Environment:
- Operating temperature: 0°C to 55°C
- Storage temperature: -40°C to 85°C
- Humidity: 5% to 95% RH (non-condensing)
- Vibration and shock resistance: Meets industrial-grade standards, suitable for harsh on-site environments such as power plants and chemical factories.
- High-Reliability Design: Supports redundant architecture (configurable as dual redundant channels), ensuring system operation remains normal in case of a single channel failure, meeting the high safety requirements of turbine control.
- Real-Time Signal Processing: Equipped with a high-speed processor to quickly collect and process turbine operating parameters, ensuring real-time control commands (typical response time in milliseconds).
- Diagnostic and Fault-Tolerant Capability: Integrates self-diagnostic functions to monitor channel faults, signal abnormalities, etc., and feeds back to the main controller via the system bus for quick troubleshooting.
- Anti-Interference Performance: Adopts optical isolation and filtering technologies to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial environments, ensuring accurate signal acquisition.
- Strong Compatibility: Specifically designed for the Mark VIe control system, it seamlessly integrates with other modules in the series (e.g., IS200CPUH1B CPU module, power modules, I/O modules) to form a complete turbine control system.
- Core control links of gas turbines and steam turbines, such as speed control, load regulation, and temperature monitoring.
- Automation control systems for turbine units in thermal power plants and combined cycle power plants.
- Precision control and protection systems for large rotating machinery in petrochemical, metallurgical, and other industries.
- Cooperates with other modules in the Mark VIe system to realize full-process control of turbines, including startup, shutdown, grid connection, and operation optimization.
- Exclusively applicable to the GE Mark VIe control system, requiring compatibility with the series' backplane, power modules, main controllers, etc.
- Supports configuration, programming, and debugging via GE's ControlST software, integrated into the configuration environment of the overall control system.
- Can be connected to plant DCS systems or SCADA systems to realize upload and remote monitoring of turbine operating data.
As a key component of turbine control systems, its stability and reliability directly affect the safe operation of units, making it widely used in energy and industrial fields with high requirements for control accuracy and safety.
