Description
GE IS220PTURH1A
- Technical Specifications:
- Series: GE Mark VIe
- Function: Primary Turbine Protection (overspeed, zero-speed, other protections)
- Processor: 667 MHz Freescale 8349
- Operating system: QNX Neutrino RTOS
- Power: 12 W, 18–36 VDC
- Environment: 0 °C to 65 °C (no fan cooling required)
- Connectivity: Dual 10/100 Mbps Ethernet ports; DC-62 connector to TTURH1C terminal board
- Inputs: Four passive magnetic speed inputs for speed detection; zero-speed detection down to 2 RPM
- Functional Features:
- Automatic reconfiguration (firmware, parameters, and I/O pack download from controller)
- Primary overspeed trip and zero-speed detection
- Internal temperature sensor, watchdog, and hardware reset
- LED indicators and infrared port for diagnostics
- Application Scenarios:
- Steam turbine primary protection systems in power plants
- Marine propulsion turbines
- Oil and gas turbine applications requiring overspeed protection
- Performance Parameters:
- High reliability with no cooling fan required
- Fast detection and response to overspeed conditions
- Material and Structural Characteristics:
- Black housing with ventilation ports
- Industrial-grade connectors and internal PCBs
- Designed for panel or rack mounting
- Working Principle:
- The module monitors magnetic speed sensor inputs to derive turbine speed. It evaluates overspeed and zero-speed conditions and issues trip signals via the DC-62 connector. It communicates with Mark VIe controllers over Ethernet for configuration and diagnostics.
- Installation Requirements:
- Mount onto TTURH1C terminal board securely
- Connect Ethernet and 18–36 VDC power per GE instructions
- Enable auto-reconfiguration in ToolboxST as needed
- Usage Notes:
- Ensure proper sensor wiring for speed inputs
- Verify overspeed and zero-speed setpoints match turbine requirements
- Perform regular testing of protection functions
