Product Title

GE IS215WEPAH2BB – Mark VI Printed Circuit Control Board (WEPA Module)

Product Overview

The GE IS215WEPAH2BB is a high‑performance printed circuit control board used in GE Mark VI and Mark VIe turbine control and automation systems. Identified by the functional acronym WEPA (Wind/Energy/Plant Automation), this module serves as a programmable control and communication interface within critical industrial automation environments. It supports data conditioning, I/O interaction, and control logic execution, and is suitable for both simplex and triple‑redundant configurations.

Designed to be installed within a VME rack alongside processor and I/O modules, the GE IS215WEPAH2BB supports configurable software frame rates (10 ms, 20 ms, and 40 ms), enabling real‑time responsiveness to operational inputs and outputs. The board integrates multiple communication standards such as IONet and UDH and features comprehensive connector capacity around its perimeter for interfacing with other system components.

This module is commonly used in power generation, turbine control systems, and other mission‑critical industrial applications where determinism, redundancy, and real‑time control are essential.

Three selectable software frame rates (10 ms, 20 ms, and 40 ms) allow optimization for control responsiveness and system throughput based on specific application requirements.

Robust Industrial Design:
Built with metal‑oxide varistor protection and industrial‑grade connectors, the GE IS215WEPAH2BB resists electrical transients and environmental stress. Connector count flexibility (2–20 pins) supports versatile peripheral interfacing.

Redundancy Support:
Compatible with simplex and triple redundant (TMR) system configurations, enabling high availability in safety‑critical environments.

Application Scenarios

Power Generation Turbine Control:
Provides local control logic and communication in gas, steam, and combined cycle turbine control cabinets, interfacing with I/O and processor modules.

Industrial Automation Systems:
Used in VME‑based automation platforms where deterministic control execution and high‑reliability communication with sensors and actuators are required.

Redundant Control Architectures:
Suitable for safety‑critical triple modular redundancy (TMR) systems in utilities and large‑scale industrial process control.
