3 Chapter 1Open Architecture Designed for AutomationFor applications demanding customized control, an UNO-4683 that usesmore flexible, off-the-shelf technology is a better option. UNO-4683 usesoff-the-shelf components such as an x86 processor, an Ethernet chipset,CompactFlash®, and DRAM. At the same time, the UNO-4683 unit canbroadcast the process data through the Ethernet and share the data withoperators and managers. By using off-the-shelf components, machinebuilders can customize the control scheme they use for other machinesthat require multiple inputs, optimized control, or Ethernet communica-tion. So, UNO-4683 offers the I/O connectivity of PCs with options like:6 x Ethernet (2 x 10/100/1000 Base-T, 4 x 10/100 Base-T), 2 x Serialports (2 x RS-232/422/485), 6 x USB ports (2 x Front, 3 x Rear, 1 x Inter-nal), 1 x CompactFlash and DVI-I interface for display panels.Robust IO Isolate System from Electrical NoiseUNO-4683 is designed for the applications in substation where is sup-posed to have certain electric interference. Equipping with isolated powerand isolated communication ports, UNO-4683 has high resistance towardelectrical noise. It has been proved not only can work well in substationbut also suitable for any harsh applicationsAn Industry-Proven DesignIndustrial applications require controllers with high-vibration specifica-tions and a wide temperature range. Controllers in industrial environ-ments require flexible and stable mounting, and many machine buildersunderestimate the need for rugged controllers because their applicationsare mounted in an industrial enclosure. UNO-4683 has a special designwithout the weaknesses of a standard PC. No fan, and no HDD preventdust and vibration problems. With a smart mechanical design, UNO-4683can meet 50 G shock (with CompactFlash), 2 G vibration (with Compact-Flash), up to 70°C operating temperature (tested under 100% CPU load-ing) and almost anything an industrial environments demand.Designed to Fit Comfortably Into RacksIn completely new packaging, UNO-4683 has standard 2U rack size as440 x 280 x 88 mm (W x H x D) could fit your rack. The rear IO connec-tion and indicator LEDs on the front panel for all ports and modes highlysimplify monitoring for operation and maintenance in the rack. You couldeasily mount UNO-4683 on rack, manage all UNOs in one rack and eas-ily develop your application on rack.
