GE IS200AEADH4A Mark VI Input/Output Grid Fork Board – Key Functions
1. Core Purpose
The IS200AEADH4A is a critical I/O interface board designed for GE’s Mark VI Speedtronic Turbine Control System.
It serves as a signal distribution hub, connecting field devices (sensors, actuators) to the turbine control processor.
2. Key Features
High-density signal routing for analog/digital I/O channels in turbine control applications
Optical isolation for noise immunity and protection against ground loops
Hot-swappable design (supports online replacement in redundant systems)
Compatible with Mark VI’s VME bus architecture for seamless integration
Built-in diagnostics for fault detection and maintenance alerts
3. Applications
Gas/steam turbine control (startup, speed regulation, shutdown sequences)
Power plant protection systems (vibration monitoring, temperature sensing)
Integration with Mark VI controller for real-time process automation
4. Advantages
High reliability in extreme environments (temperature, EMI)
Modular design simplifies troubleshooting and spare part management
Legacy support for existing Mark VI installations
