GE IS200AEPAH1AHD Mark VIe I/O Module Circuit Board (PCB) – Key Functions
1. Core Purpose
The IS200AEPAH1AHD is a critical I/O module PCB designed for GE’s Mark VIe Speedtronic Turbine Control System.
It functions as a signal conditioning and processing interface, enabling communication between field devices (sensors, actuators) and the Mark VIe controller.
2. Key Features
High-speed signal processing for analog/digital I/O in turbine control applications
Integrated protection circuits (surge suppression, optical isolation) for noise immunity
Hot-swappable design (supports online replacement in redundant configurations)
Ethernet-based communication (TCP/IP) for real-time data exchange with the Mark VIe controller
Built-in self-diagnostics for fault detection and predictive maintenance
3. Applications
Gas/steam turbine control (speed regulation, load balancing, emergency shutdown)
Power plant automation (vibration monitoring, temperature/pressure sensing)
Integration with Mark VIe control system for distributed I/O management
4. Advantages
Enhanced reliability in harsh industrial environments (high temp, EMI, vibration)
Modular architecture simplifies maintenance and system upgrades
Legacy compatibility with existing Mark VIe installations
