net-line FW-50

Versatile and powerful remote terminal unit

The net-line FW-50 is a modular, universally usable remote terminal unit, which can at the same time be used as a high-stability router (if required also with redundancy) for demanding communication and automation applications. Up to six separate network segments allow the control centre and process LANs to be decoupled.

Application areas

A series of powerful functional modules forms the basis of the numerous possibilities for using the FW-50. These include for example convenient cross-connection of information between different telecontrol stations, as well as the integration of external components (for instance protective device coupling via IEC 61850 or IEC 60870-5-103).

The most common applications of the FW-50 include its use as

  • a station and bay controller in medium-voltage and high-voltage switching stations with bay and power system control technology
  • a monitoring and control device in utilities and waste disposal operations and in industry
  • a monitoring and control device in gas pressure regulator stations and block valve stations
  • a data acquisition and communication system in transport and infrastructure applications

A particular strength of FW-50 lies in the implementation of communication tasks with substations and control systems of many different manufacturers.

Communication paths and capacity

In combination with external or SAE communication modules, a wide range of possible communication paths can be realised. These include:

  • Dedicated lines
  • Dial-up line
  • FunkLAN (Radio LAN)
  • TETRA radio
  • FO, fiber optics
  • DSL and SHDSL
  • 3G/4G mobile communication via GPRS, EDGE, HSPA/UMTS and LTE

In addition, an extensive range of plug-in measuring, set point, indication, command as well as mixed and special cards are available. You can find a complete list in the data sheet.
