Ethernet Routers

The REX 100 routers are designed to be used in conjunction with the myREX24 V2 portal. Programming and setup for remote maintenance is carried out through the Cloud based portal. With the integrated digital inputs, alarms can be sent via the myREX24 V2 portal as an SMS message or e-mail. The USB host port present in all devices enables the connection of USB devices (e.g. programming port of a drive) via the remote maintenance tunnel (USB-over-IP). The WAN port establishes the connection to the myREX 24 V2 portal allowing access to the additional Ethernet participants connected to the router LAN via the integrated 3-port switch. For data transmission, the industrial router uses an encrypted VPN tunnel based on the secure OpenVPN protocol.
