ATLAS II

The Atlas-II programmable control is designed specifically for prime mover control applications such as: 

  • Gas Turbines & Steam Turbines 
  • Compressor Control and Protection 
  • Gas and Diesel Engines 
  • Hydro Turbines

The ATLAS II is a low cost alternative to a general purpose PLC as it has the option to incorporate the following functions:

  • Speed control
  • Synchronisation
  • Load sharing
  • Generator protection
  • Prime mover sequencing
  • Import/export control

The Atlas-II control is available in several configurations to meet the specific I/O needs of the prime  mover. The modular hardware configuration of the Atlas-II lends itself to bulkhead mounting.

Hardware modules can support a variety of analog and digital signals including thermocouples, RTDs, 4–20 mA signals, and others. Control power for the Atlas-II is supplied from an external 24 Vdc source.

Environmental specifications allow the Atlas-II control to move out of the control room and closer to the prime mover. In many cases, it can be mounted on the prime mover skid. Typically, the Atlas-II control is mounted in an enclosure rated for the site-specific environmental conditions.

The Atlas-II platform supports Profibus and Ethernet field architectures for remote distributed I/O.
