Industrial ethernet extender

The Westermo DDW-120 high-speed industrial ethernet extender utilises SHDSL transmission technology, allowing existing twisted pair cables to be used to establish a high-speed remote connection between two ethernet networks.

With transfer rates up to 5.7 Mbps and an operating distance of up to 15 km at lower data rates, this is an alternative to fibre-optic or radio systems when linking remote ethernet networks.

The units are designed for use in harsh industrial environments, featuring a DIN-mounted case, total galvanic isolation and transient protection for all interfaces, -40 to 70 °C operating temperature and redundant power inputs that enable the use of two separate supplies with an operating voltage range of 10-60 VDC for uninterrupted communication.

Communications are transparent for multicast addressing, VLAN packet and allow VPN pass-through for IPSec. It can also be used with protocols like Modbus/TCP and Profinet IO.
