AC 700F controller

The AC 700F controller has a small footprint and supports PROFIBUS. It can support up to eight direct I/O modules.

The AC 700F controller, as a member of Freelance, has numerous advantages over a PLC based solution:
  • The distributed process control system (DCS) simplifies engineering, commissioning and maintenance of the automation system.
  • Visualization is directly incorporated into the engineering, making configuration particularly straightforward.

AC 700F can also be extended with Profibus Remote I/O units. In addition, field devices can be connected to AC 700F. Thanks to the flexibility of Ethernet and its small footprint, AC 700F can also be placed in junction boxes in non-hazardous areas out in the field as competitive, intelligent Ethernet I/O.
