Westermo ethernet extender

Saturday, 14 March, 2009 | Supplied by: Paqworks

Westermo has released a high-speed industrial ethernet extender. The DDW-120 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 easy-to-install alternative to fibre-optic or radio systems when linking remote ethernet networks.

The units are well prepared for use in harsh industrial environments. Total galvanic isolation and transient protection are standard for all interfaces and the line interfaces are also equipped with extensive protection against overvoltages and transients. The DIN-mounted case makes the unit robust and allows for the surrounding air temperature to be between -40 to 70 °C. To allow for uninterrupted communication the units are equipped with redundant power inputs that enable the use of two separate supplies with an operating voltage range of 10-60 VDC.

DDW-120 is transparent for multicast addressing and VLAN packets and allows VPN pass-through for IPSec. It can also be used with protocols like MODBUS/TCP and Profinet.
