net-line FW-5

Compact and cost-effective

The net-line FW-5 is the extendible small-scale station of the high-performance series5 product family. The extremely compact bay station controller for top-hat rail mounting comprises all the components that a high-performance telecontrol and automation system needs for monitoring, control, logging and transmission. This makes it a viable solution for requirements in the area of telecontrol or station control and automation technology. The FW-5 is designed to assume the tasks of many different small applications with its own capacity.

Application areas

  • Field device in transformer substations with protection device coupling
  • Intelligent secondary unit substation including power quality monitoring systems, earth fault and short circuit indicators in the outgoing circuits
  • Control box for direct marketing and control energy
  • Feed-in management in renewable energy plants
  • Intelligent measurement point for wide range regulation in distribution networks
  • Monitoring of media and infrastructure systems in pipelines
