Description

IS200EISBH1AAA: Product Overview​
The GE IS200EISBH1AAA​ is an analog I/O board designed specifically for GE Mark V gas turbine control systems, a legacy platform renowned for its reliability in industrial power generation. As part of the Mark V ecosystem, it acts as a “signal conditioner” for analog inputs from field devices (e.g., turbine blade position sensors, fuel flow meters) and analog outputs to actuators (e.g., servo valves, pumps). Its primary role is to ensure accurate signal transmission between the field and the VMEbus controller, which is critical for maintaining turbine stability and efficiency.
Role in Automation Systems:
Positioned as a “field signal interface” in Mark V architectures, the IS200EISBH1AAA performs two key functions:
  1. Signal Conditioning: Receives raw analog signals from field devices (e.g., a thermocouple measuring turbine exhaust temperature) and scales/conditions them into a format suitable for the VMEbus controller (e.g., converting millivolt signals to 4–20 mA current loops).
  2. Signal Transmission: Sends conditioned analog signals to the VMEbus controller for processing (e.g., adjusting fuel flow based on temperature readings) and receives control signals from the controller to drive actuators (e.g., opening a valve to increase coolant flow).
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 V components without major system upgrades.
  • Flexible Signal Handling: Supports multiple analog signal types (LVDT, thermocouple, 4–20 mA, ±10 V DC) through configurable input channels, making it adaptable to diverse field devices.
  • Galvanic Isolation: Uses optocouplers to isolate field devices from the controller, protecting sensitive electronics from voltage spikes and electromagnetic interference (EMI) in harsh industrial environments.
  • High Precision: Provides accurate signal scaling (e.g., 12-bit resolution for analog inputs) to ensure reliable data for turbine control algorithms.

Platform Benefits (Mark V Series):
The IS200EISBH1AAA inherits the Mark V platform’s strengths, including:
  • Reliability: The Mark V 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 V components (e.g., contactors, I/O modules), 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 Conditioning:
The IS200EISBH1AAA’s ability to scale and condition analog signals ensures that the VMEbus controller receives accurate data from field devices. For example, in a power plant, the board can precisely measure turbine exhaust temperature (via a thermocouple) and convert it to a 4–20 mA signal for the controller, which adjusts fuel flow to maintain optimal efficiency.
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 (0°C to +55°C) and compact form factor make it suitable for harsh industrial environments. Its DIN rail mounting option simplifies installation in crowded control cabinets.
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.
