GE IS200AEPAH1BGB IS215WEPAH2BA Printed Circuit Board

IS215WEPAH2B Technical Specifications

Product Overview

The IS215WEPAH2B is a printed circuit board (PCB) used in GE Energy’s Mark VIe Speedtronic wind turbine control system. Specifically designed as a Wind Energy Pitch Axis, the module plays a critical role in the automation of drive systems for wind turbines.

The product’s functional acronym "WEPA" embedded in its part number highlights its specialized function. It represents a refined version of the original WEPA board, featuring a functional revision "B", which improves performance and efficiency while maintaining the original form factor and aesthetics.

Key Features and Hardware Details

Like other PCBs in the Mark VIe series, the IS215WEPAH2B includes a wide range of hardware components that enable its wind energy pitch axis functionality:

Input/Output Specifications:

• 8 analog inputs

• 1 incremental encoder input

• 1 additional analog input (separate from the group above)

• 20 discrete inputs

• 2 discrete outputs

• 9 relay outputs

• 2 RS-485 communication interfaces

• 2 PWM (pulse-width modulated) control outputs

These inputs and outputs support the board's role in processing real-time data and controlling pitch mechanisms in wind turbine applications.

Assembly and Design Notes

The IS215WEPAH2B board is part of a special modular assembly, identified by the "IS215" prefix, which signifies:

• PCB style assembly

• U.S. manufacture, specifically at GE’s Salem, Virginia facility

This module includes:

• AEPAH1B baseboard

• BPPB daughterboard

Together, they form the complete WEPA assembly.
