Atlas-II Turbine and Engine Control Platform

 

The Woodward 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's software logic and inputs/outputs are designed to be customized for an application's specific 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.

Features of the Atlas-II control platform include:

  • Total system control
  • Powerful CPU for demanding applications
  • Real-time multitasking VxWorks® operating system
  • Deterministic update rates as fast as 5 ms
  • Improved control system availability and reliability
  • SNTP compliant for time synchronization
  • Four Ethernet ports
  • Distributed I/O capability
  • Profibus
  • Ethernet
  • Low cost alternative to a general purpose PLC
  • CE and UL compliant, marine type approved
