tBOX323-835-FL - Intel Atom E3845 1.91GHz Bay Trail-I Embedded Rail PC with EN 50155/EN 50121 certification and EN 45545-2 compliance (-40C to +70C)
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.
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.
The Taiwan Excellence is an award delivered by the Ministry of Economic Affairs (MOEA) and Taiwan External Trade Development Council (TAITRA) to encourage Taiwanese industries to upgrade and incorporate value into their product design. The Taiwan Excellence Award is based on four different criteria : research and development, design, quality, and marketing. Each product must score high in each category in ordered to be selected.
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 and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.
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.
EN 50121 Industrial standard for Railway Networking and Communication products
These devices offer EN 45545 fire protection approval when installed in railway vehicles
