Part Number: IS200AEPAH1A
Functional Acronym: AEPA
Functional Description: Alternative Energy Pitch Axis
PCB Coating: Conformal Coating
Functional Revision: A

Overview

The IS200AEPAH1A is a specialized printed circuit board (PCB) developed by GE Energy for the Mark VIe Wind turbine control system. Part of the long-standing Speedtronic control platform originally developed in the 1960s for steam and gas turbines, this model has been adapted for renewable energy applications. Specifically, the AEPA board functions as an Alternative Energy Pitch Axis controller and is a revised version of the original IS200AEPAH1.

Hardware Features & Specifications

• Auxiliary Board: Optional auxiliary board mounted via screws and standoffs

• Processor Interface: Communicates with the main processor via two male pin connectors (top left corner)

• Key Components:

• Multiple integrated circuits

• 2 female phone plugs

• 1 three-pin female connector

• 2 LED indicators (left edge of the board)

• Surge Protection:

• 6 Metal Oxide Varistors (MOVs) aligned in a single row

• MOVs help protect the board from voltage spikes by varying resistance based on voltage levels

• Relay & Connectors:

• 12 Relays

• 17 vertical female-pin connectors ranging from 2 to 20 pins, located along the board edges

• Plated Mounting Holes: Large, factory-made, some plated for grounding or voltage storage purposes

Supported I/O Types

• Analog Inputs: 8

• Analog Output: 1

• Incremental Encoder Input: 1

• Absolute Encoder Input: 1

• Discrete Inputs: 20

• Discrete Output: 1

• Relay Outputs: 8

• RS-485 Interfaces: 2

• Brake Control Output: 1

These I/O specifications are similar to the Mark VIe BPPB board, also used for wind turbine control and available through related suppliers.

Application

The IS200AEPAH1A plays a vital role in controlling the pitch axis of wind turbines, allowing for precise blade angle adjustments to optimize energy capture and ensure safe operation. Its design supports high-reliability environments, robust communication, and broad I/O compatibility, making it a key component in wind energy systems.
