The GE IS200WROBH1A Relay Power Sensing Board is a specialized printed circuit board (PCB) designed for General Electric’s Mark VI/Mark VIe turbine control systems.
It plays a critical role in power monitoring and relay-based protection for gas/steam turbines in power generation and industrial applications.
1. Primary Functions
Power Sensing & Monitoring:
Measures electrical parameters (e.g., voltage, current, or frequency) from turbine systems or connected equipment.
Provides real-time feedback to the Mark VI/Mark VIe controller for system health assessment.
Relay Control & Protection:
Triggers protective relays in response to abnormal conditions (e.g., overvoltage, underfrequency, or phase imbalance).
Ensures safe turbine shutdown or load shedding during faults.
Signal Conditioning & Isolation:
Filters and isolates sensor signals to prevent noise interference in the control system.
May include optocouplers or transformers for galvanic isolation.
Redundancy & Diagnostics:
Supports redundant configurations for high-reliability applications.
Features LED indicators for fault detection and operational status.
2. Key Features
Industrial-Grade Design: Built to withstand harsh environments (temperature extremes, vibration, EMI).
Modular & Hot-Swappable: Allows replacement without turbine shutdown.
Compatibility: Integrates with other IS200-series I/O modules in the Mark VI/Mark VIe system.
3. Typical Applications
Turbine Protection Systems (e.g., overspeed, underfrequency trips).
Generator Monitoring (e.g., synchronizing, load balancing).
Grid-Connected Power Plants (e.g., fault detection, islanding prevention).
