net-line FW-5-GATE

The compact and communicative micro remote terminal unit

The FW-5-GATE is the compact communication specialist in our portfolio: It has been designed for especially communication-intensive applications involving telecontrol, substation control and automation. In order to offer even more communication options in a small space, integrated inputs/outputs have been omitted. Like the FW-5, the FW-5-GATE can of course also be extended individually with extension boards. It offers cost-effective solutions for intelligent secondary distribution networks and smart metering via further interfaces, for integration of SML/SyM² meters, for instance. A temperature sensor integrated in the remote terminal unit measures the station temperature.

The FW-5-GATE for top-hat rail mounting is equipped with further interfaces for coupling external components to form intelligent networks. From the network to the Smart Grid – this communication genius can master all that. As with all the devices of the series5 series of products, the connection to the control centre can be made by numerous communication routes and protocols directly or with telecontrol interfaces – backed up with redundant systems if required.

Local meter integration is made via the second LAN connection with SML protocol or via the additional serial interface with IEC 62056-21 protocol. S0 meter pulse detection can also be used in the CL variant.

Application areas

  • Intelligent secondary unit substation with integration of earth fault/short circuit indicators, network analysis systems and protective devices
  • Smart meter integration in energy management systems and remote meter reading control centres
  • Intelligent measurement point for wide range regulation in distribution networks
  • Field device in transformer substations with protection device coupling
  • Monitoring of media and infrastructure systems in pipelines
