ARK-2231R - Intel Atom E3845 1.91GHz Fanless Embedded Rail PC with HDMI/VGA, dual Gigabit Ethernet, 3x USB ports and IEC61373 Cat 1 Class B shock proof
CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.
This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.
Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.
VESA is a mounting standard for displays and systems and consists of four screws arranged in a square with the horizontal and vertical distance between the screw centres.
These products use heatsink, heatpipe and extrusion technology to dissipate the heat generated by the system rather than using traditional fans thus improving system reliability and longevity.
EN 50155 is the European standard for electronic devices used in railway applications. The device must adhere to the strict specifications of EN 50155 including -25C to +70C wide operating temperature range, resistance to humidity, shocks, vibrations and radiation – all environmental demands encountered in the rail industry.
These devices have been designed to be mounted directly on to an industry standard DIN-rail.
The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.
These products utilise high quality industrial grade components enabling them to work in extended wide temperature environments. They are capable of running below -20C and above +70C and offer further protection than standard wide temperature rated products.
