The new MRD-310 and MRD-330 are robust 3G routers designed for remote access across mobile networks. They provide a very high level of connectivity, and support many mobile standards including GSM, GPRS, 3G UMTS, HSDPA and HSUPA allowing uplink transfer rates of up to 2Mbit/s. Together with the rugged enclosure, DIN-rail mounting and an operating voltage range spanning from 10 VDC to 60 VDC, they are designed for industrial applications in harsh environments. Typical on board (train, trucks, etc.) or ground applications include video surveillance, SCADA/DNP3 telemetry systems and remote access to machines and devices.
The Westermo 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 5.7 Mbits/s and with an operating distance of up to 10 kilometres at lower data rates, this is an easy-to-install alternative to fibre optic or radio systems when linking remote Ethernet networks. The DDW-220 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.
