The Woodward Atlas II is a compact, cost-effective turbine and engine control platform designed for smaller machines and OEM applications that do not require the full I/O count of the MicroNet Plus. It delivers reliable, deterministic prime mover control using a proven real-time operating system, with four Ethernet ports and add-on fieldbus modules for modern plant communication architectures. The Atlas II is equally at home on gas turbines, diesel and gas engines, compressors, and steam turbines.
Key Features
Hardware
- Modular hardware configuration with bulkhead mounting
- Analog and digital I/O modules: thermocouples, RTDs, 4-20 mA, discrete
- 24 Vdc external control power supply
- Environmental specs allow skid mounting near the prime mover
- Profibus and Ethernet fieldbus for remote distributed I/O
Communications and Performance
- Four Ethernet ports for network flexibility and redundancy
- Add-on fieldbus communication modules (Profibus, Ethernet)
- Rigorous load rejection performance
- Incipient surge detection
- Dedicated I/O for deterministic prime mover control; free-time programming for less critical functions
- Programmed using Woodward GAP (function block) or Ladder Logic
- Real-time service tools for monitoring and troubleshooting
Applications
- Gas turbines
- Diesel and gas engines
- Steam turbines
- Hydro turbines
