Industrial Ethernet Router, REX 100 LTE (EU- & Asia version)

REX 100 LTE, 4 x LAN (switch)/1 x LTE modem (EU- & Asia-Version)

Ethernet participants, such as PLC control systems, can be reached with the REX 100 industrial routers, irrespective of the manufacturer.

The REX 100 routers are systematically designed to operate in conjunction with the myREX24 V2 portal: All programming and remote maintenance is carried out exclusively through the portal. 
With the digital inputs, alarms can be sent via the myREX24 V2 portal as SMS and 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 REX 100 LTE is equipped with an LTE modem with which the connection to the myREX 24 V2 portal is established. Additional Ethernet participants can be connected at the router via the integrated 4-port switch. For data transmission, our industrial router uses an encrypted VPN tunnel on the basis of the secure OpenVPN protocol.
