Description
Viper-008 is a unmanaged switch developed for rail and industrial applications. To meet
the environmental requirements from rail and harsh industrial applications the switch
has rugged M12 Ethernet connectors and full metal housing. The IP65 sealed metal case
make it robust and allows for the surrounding air temperature to be between -40 to
+70°C. There are no sensitive or fragile components, hardening the product against
shock and vibration making these units suitable for rolling stock usage. The power supply
operates over a wide input range from 24 to 110 VDC.
