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.

DIN-rail mountable

These devices have been designed to be mounted directly on to an industry standard DIN-rail.

Extended Wide Temperature

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.


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.

FCC Approved

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.


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.

Wide Voltage

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.
