Managed Industrial Ethernet Switch – RFR-12-FB
The RFR-12FB is one of managed industrial ethernet switch products that has been specially designed to allow the creation of a fault tolerant Ethernet backbone structure in trains. The dual bypass relay ensures that aggregated links between carriages are maintained, even if one carriage has a power failure. The 12 100 Mbit/s Ethernet ports support the extended specification 185 m standard so even if several carriages are bypassed, communication is maintained. The Westermo WeOS operating system provides an extensive suite of IP networking standards allowing resilient and flexible networks to be created, meeting the needs of the rail market.
As is critical for all equipment to be installed in rail vehicles, The Westermo Managed Industrial Ethernet Switch RFR-12-FB has been externally tested across the complete spectrum of standards required by EN50155.
Westermo understand that systems on railcars are required by the EN50155 standard to have a useful life of 20 years, so as well as using the highest quality components to deliver extended MTBF figures, we also implement features like the Gor-tex® membrane in the IP65 enclosure to prevent water build up in the units.
The EN50155 standard requires mandatory performance and isolation testing. Not only does Westermo meet these, we exceed them in order to meet the additional manufacturer requirements for train control. Westermo’s Swedish factory has been building Ethernet switch for the railcar market for many years now and understands the measures that are required to provide the highest quality manufactured solutions.
