RSR Rugged Rail Switches

                                                RSR Series        Belden have discontinued the Hirschmann RSR series (RSR20/30).

Maximum reliability in mission-critical applications.

The manageable switches of the Hirschmann RSR family are offered in a Fast (RSR 20) and a Gigabit Ethernet version (RSR 30) are designed for extremely high demands with regard to shock and vibration resistance as well as electromagnetic compatibility (EMC) Ultra-hardened DIN rail switches (i. e. shock, vibration and temperatures fluctuating between – 40° C and + 85° C), the rugged RSR Hirschmann rail switches deliver the performance you need. They have a compact metal housing and can be mounted both on DIN rails and on the wall.

The RSR rail switches are built to take the punishment in marine, rail, road and other transportation automation applications including fibre optic rail networks, train station passenger information systems, conveyors and airport runway lights.

19 versions can be configured individually with up to 26 ports including up to 3 Gigabit Ethernet ports and individually configurable uplink ports.

With flexibility of power supply, the RSR switches can be configured with wide-voltage power supplies from 16.8-60VDC or 48-320 VDC and 90 - 265 VAC with no need for an external power supply. RSR series switches are available with optional gigabit ports and an extended temperature range of -40C to + 85C. Ultra-fast ring recovery times under 10ms are possible using HiPer-Ring redundancy protocol and the switch's robust metal housing offers extended RFI/EMI and vibration immunity. The RSR switches go above and beyond the already rugged capabilities of Hirschmann's switches by being extremely immune to noise and able to provide maximum  up time in extreme environmental conditions.
