GE IS215WEPAH2AB non-CANBus Wind Pitch Axis Control Module
Description:
The GE IS215WEPAH2AB is a high-reliability non-CANBus Wind Pitch Axis Control Module designed for advanced wind turbine management within GE’s Speedtronic Mark VI control system. Engineered to optimize blade pitch angles, it ensures efficient energy capture, load reduction, and emergency shutdown capabilities, critical for onshore and offshore wind farm operations.
As a core component of the Mark VI architecture, the module integrates seamlessly with terminal boards and control systems to deliver real-time monitoring and actuation. It supports IONet and UDH communication protocols for robust data exchange with the turbine’s main control system, eliminating reliance on CANBus while maintaining high-speed, deterministic performance. With a focus on safety and durability, it features triple-redundant processing and conformal coating to withstand harsh environmental conditions, including extreme temperatures, humidity, and mechanical vibrations.
- Non-CANBus Communication: Utilizes IONet and UDH for secure, high-speed data transmission, ensuring compatibility with GE’s Mark VI systems and broader turbine control networks.
- Triple Redundancy: Implements a 1oo3 voting architecture to minimize single-point failures, providing continuous operation even during component faults.
- Precision Control: Manages blade pitch angles with sub-millisecond response times, optimizing aerodynamic efficiency and protecting against overspeed events through direct control of servo drives and solenoids.
- Flexible I/O: Supports digital inputs/outputs and analog inputs, enabling comprehensive monitoring of turbine dynamics.
- Environmental Resilience: Conformal coating and industrial-grade components ensure reliable operation in temperatures ranging from -40°C to +70°C, with resistance to dust, moisture, and salt mist.
- Safety Compliance: Aligned with IEC 61508 SIL 2 standards, it integrates with the turbine’s safety chain to execute emergency pitch-down commands, ensuring fail-safe shutdowns.
- Diagnostic Capabilities: Front-panel LEDs and built-in self-tests enable rapid fault detection, while remote diagnostics via IONet facilitate predictive maintenance and reduce downtime.
