GE Fanuc IS200AEPAH1BJD(IS215WEPAH2BB) Printed Circuit Board

IS215WEPAH2BB Technical Specifications

Product Overview

The IS215WEPAH2BB is a high-performance printed circuit board (PCB) developed for use in GE’s Mark VI control system. Known by its functional acronym WEPA (Wind Energy Pitch Axis), this board is compatible with both simplex and triple-redundant applications and integrates into a fully programmable control environment.

Programmable Control and Software Frame Rates

This PCB supports three software frame rates—10, 20, and 40 milliseconds. These frame rates define the cycle time for:

• Conditioning and reading inputs

• Executing application software

• Sending output signals

Application software updates can be performed on-the-fly while the main process is running, protected by five levels of password security.

Hardware Features

• 20 Female Plug Connectors:
  Located around the board’s perimeter, with varying pin counts (2–20 pins) for versatile connectivity.

• Daughterboard:
  Installed in the lower right-hand corner, enhancing functional capabilities.

• Metal Oxide Varistors (MOVs):

• 3 MOVs positioned together on the lower left

• 1 MOV located in the upper right corner
  These components provide critical surge protection.

Installation & Integration

The IS215WEPAH2BB is typically mounted in a VME rack, available in 13-slot or 21-slot configurations, which itself is installed within the Control Module. The system includes:

• This WEPA PCB (occupying one slot)

• A variety of I/O cards

• The main processor card

The board is optimized for seamless integration into turbine control systems, particularly in high-reliability environments requiring redundancy and real-time processing.
