The REX 250 Ethernet Router- New product from Helmholz

With the REX 250 industrial routers, Ethernet subscribers, such as PLC controllers, can be achieved regardless of manufacturer


The Helmholz REX 250 routers are designed for operation in conjunction with the myREX24 V2 portal: The complete parameterization and remote maintenance is carried out via the portal. In addition to remote maintenance, the REX 250 routers can also read data from the PLC, visualize and generate alarms. For remote maintenance and data transmission, the industrial router uses an encrypted VPN tunnel based on the secure OpenVPN protocol.

The REX 250 routers also enable remote maintenance and data access to PLCs via an MPI / PROFIBUS and via an RS232 interface.

With the 4 digital inputs, alarms can be sent via SMS and email via the myREX24 V2 Portal. The 2 digital outputs can change the system states of the router, e.g. with a lamp on the control cabinet, or can be activated via the portal.
The USB host interface available on all devices enables the connection of USB device devices (eg programming interface of a drive) via the remote maintenance tunnel (USB-over-IP).

The REX 250 WAN has a WAN interface via which the connection to the myREX24 V2 portal is established. The integrated 4-port switch can be used to connect the Ethernet nodes of the machine to the router on the available RJ45 ports.
