EN 50155

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.

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.

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.

Wireless Connectivity

These devices have built in wireless interface controllers enabling them to connect to a wireless network.
