The DDW-220 is an Ethernet extender enhanced with a built-in four port Ethernet switch which allows this one unit to be used to create entire Ethernet solutions. Existing twisted pair cables can be used to establish a high speed remote connection between two Ethernet networks. With transfer rates up to 5.7Mbits/s and with an operating distance of up to 10km at lower data rates, this is an alternative to fibre optic or radio systems when linking remote Ethernet networks. The extender uses a transient blocking unit on each DSL line to provide both over-current and over-voltage protection on the line allowing it to handle indirect lightning strike transients, power induction and short circuit problems. The unit combines the functions of an extender using any twisted pair cables and a switch. This plug-and-play unit covers many applications offering data rates from 192Kbit/s to 5.7Mbit/s in both directions over distances of up to 10km.

With the April issue, we celebrate the 40th anniversary of IEN Europe. For that occasion we present numerous interesting articles and interviews on technologies that have been groundbreaking over the past decades. An interview with Nexans is on the Evolution of Cables . A technical article by the EMVA on Machine Vision emphasizes the milestones that have been important for the automation industry. A very recent and up-to-date topic, Industry 4.0, is discussed in an Interview with Wibu Systems, a company dedicated to the protection of know-how. IEN Europe April also features a retrospective on Low-voltage Switchgear by Eaton. To celebrate IEN’s 40th anniversary properly, we have a Reader Offer for you, where you can win a high-tech visual IR thermometer. So please celebrate with us and enjoy!
