SPECTRE RT 300 Series Ethernet Routers
B&B Electronics' new SPECTRE RT 300 series, industrial wired, Ethernet routers are designed to securely connect Ethernet and serial equipment in tough environments where office/home-grade routers can't handle the job. Much like the Linksys router in homes, the rugged SPECTRE RT can connect a private network to a public one. But unlike such routers, the compact 1.7 x 3.1 x 4.5 inch SPECTRE RT was designed for harsh environments, such as cramped cabinet spaces and the outdoors, and features a wide (-40 to 75°C) operating temperature, a compact DIN-rail mount, a rugged metal case, the ability to use 10 to 30VDC power input and I/O that can be used to monitor door closures or set alarms.
