GE IS200AEADH1ABA | Mark VI Series Input/Output Grid Fork Board for Turbine Control

Description

IS200AEADH1ABA: Product Overview​

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).

• 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 VI 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).

• Reliability: The Mark VI system is the industry standard for gas turbine control, with a proven track record of 24/7 operation in power plants worldwide.
• Legacy Compatibility: The board is designed to work with existing Mark VI 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).
