Woodward Electronic Controls

Electronic Controls for Steam Turbines and Compressors

Atlas-II™ Programmable Control Platform

Woodward’s Atlas-II™ industrial control platform operates prime mover control applications:

gas turbines
compressor control/protection
gas/diesel engines
steam turbines
hydro turbines

This programmable controller is designed to have its software logic and inputs/outputs customized to meet the specific application’s requirements.

With a proven real-time operating system and dedicated inputs and outputs, the Atlas-II provides reliable and deterministic performance for key prime mover control functionality. Less critical control functionality can be added into the Atlas-II through the use of free-time programming structures and distributed I/O.
