Overview

The GE IS200AEPAH1AHD is a specialized Analog Electrostatic Protection and Processing (AEPA) board designed for GE Mark VI and Mark VIe control systems, primarily used in gas and steam turbines. This printed circuit board (PCB) functions as an analog input processor, conditioning and digitizing signals from field devices such as sensors and transmitters. Typically, it resides in a dedicated slot within the VME chassis and connects to terminal blocks for field wiring.

The IS200AEPAH1AHD supports up to 16 differential analog inputs, with signal ranges including ±10 V and 0–20 mA. It uses 16-bit A/D converters with programmable gain amplifiers for precise linearization and scaling. Furthermore, the board supports Triple Modular Redundancy (TMR) by mirroring channels across R, S, and T cores, allowing voting logic for enhanced fault tolerance. Its conformal coating and industrial-grade components ensure reliable performance even in harsh environments.

Technical Data

Typical Applications

• Turbine Control Systems: Captures analog signals from temperature, pressure, and flow sensors in gas and steam turbines.

• Power Generation Facilities: Supports real-time monitoring and control of auxiliary systems and rotating equipment.

• Industrial Automation Panels: Used in OEM and retrofit solutions for high-density analog signal acquisition.

• Redundant Safety Architectures: Enables fault-tolerant control using TMR configurations in critical infrastructure.

• Process Control Systems: Interfaces with field instrumentation for accurate data acquisition and diagnostics.

For example, engineers deploy the IS200AEPAH1AHD in turbine enclosures to digitize analog signals and ensure reliable input processing. Additionally, its support for TMR and conformal coating makes it well-suited for high-reliability applications in harsh industrial environments.
