Description

IS200AEPAH1AEC: Product Overview​
The GE IS200AEPAH1AEC​ is a pitch axis control board designed specifically for GE Mark VIe wind turbine control systems, a legacy platform renowned for its reliability in industrial power generation. As part of the Mark VIe ecosystem, it acts as a “signal gateway” between field devices (e.g., turbine blade position sensors, fuel flow meters) and the VMEbus controller, ensuring accurate signal transmission and real-time monitoring—critical for maintaining turbine stability and efficiency.
Role in Automation Systems:
Positioned as a “field signal interface” in Mark VIe architectures, the IS200AEPAH1AEC performs two primary functions:
  1. Signal Acquisition: Receives analog/digital signals from field devices (e.g., a thermocouple measuring turbine exhaust temperature) and converts them into a format suitable for the VMEbus controller.
  2. Signal Routing: Directs processed signals to the VMEbus controller for real-time analysis (e.g., adjusting fuel flow to maintain optimal efficiency) and routes control commands from the controller to field actuators (e.g., solenoid valves).
Core Functionality:
  • VMEbus Compatibility: Conforms to VMEbus Rev. C.1, ensuring seamless integration with VME64 backplanes and controllers (e.g., GE Fanuc 90-30 series). This allows the board to work with existing Mark VIe components without major system upgrades.
  • Flexible Signal Handling: Supports multiple signal types (LVDT, thermocouple, 4–20 mA, ±10 V DC) through configurable input channels, making it adaptable to diverse field devices.
  • High Precision: Uses 12-bit analog-to-digital converters (ADCs) for accurate signal conversion (error < ±0.1% full-scale), critical for maintaining turbine stability.
  • Rugged Design: Industrial-grade components and a compact form factor enable 24/7 operation in high-temperature, high-vibration environments (e.g., power plant turbine halls).
Platform Benefits (Mark VIe Series):
The IS200AEPAH1AEC inherits the Mark VIe platform’s strengths, including:
  • Reliability: The Mark VIe system is the industry standard for wind turbine control, with a proven track record of 24/7 operation in wind farms worldwide.
  • Legacy Compatibility: The board is designed to work with existing Mark VIe components (e.g., I/O modules, contactors), reducing the cost of system upgrades.
  • Scalability: Supports expansion with additional I/O modules to accommodate growing system demands (e.g., adding more sensors to a turbine control system).

Core Features & Customer Value​
1. Reliable Signal Transmission:
The IS200AEPAH1AEC’s galvanic isolation and VMEbus compatibility ensure accurate signal transmission from field devices to the controller, even in electrically noisy environments. For example, in a wind farm, the board can reliably measure turbine blade position (via an encoder) and transmit the data to the VMEbus controller, which adjusts the pitch to maximize energy capture.
2. Flexible Configuration:
Configurable input/output channels allow engineers to customize the board’s functionality for different field devices, reducing the need for additional signal conditioning hardware. This flexibility saves time and money during installation.
3. Rugged Industrial Design:
The board’s operating temperature range (-10°C to +50°C) and compact form factor make it suitable for harsh industrial environments. Its conformal coating provides protection against dust and minor environmental impacts, extending the board’s lifespan.
4. Easy Integration:
VMEbus compatibility ensures seamless integration with existing VMEbus systems, minimizing downtime and effort during upgrades. This is invaluable for facilities with legacy VMEbus installations, allowing them to enhance system capabilities without replacing entire architectures.
