Class 1 Division 2 Certified

The National Electrical Code (NEC) defines hazardous environments as areas “where fire or explosion hazards may exist due to flammable gases, vapours, liquids, dust or particles”. When such materials are found in the atmosphere of an area, a potential for explosion exists, which could be ignited if an electrical or other source of ignition is present. As defined by the classification authorities, certified devices are suitable for installation and operation within a Class 1, Division 2 environment. Class 1 environments are areas where there is a presence of flammable gases or vapours in the air, such as natural gas or petroleum vapour. Facilities including oil rigs, refineries, gas plants and automotive repair centres all fall within this category.

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.

DIN-rail mountable

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

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.

Wide Temperature

These products utilise high quality industrial grade components enabling them to work in wide temperature environments. They are capable of running as low as -20C and as high as +70C.

5 Year Warranty

These products come with a standard five year manufacturer warranty.

ATEX approved

ATEX is the name commonly given to the European Directive 94/9/EC, also known as ATEX 95 or ATEX Equipment Directive. The regulation applies to all equipment intended for use in explosive atmospheres, whether electrical or mechanical, including protective systems. There are two categories of equipment 'I' for mining and 'II' for surface industries. The directive covers a large range of equipment, potentially including electrical equipment used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where a potentially explosive atmosphere may be present.


NEMA TS2 is a standard for traffic control assemblies, such as traffic lights, emergency road condition and pedestrian signs. The standard is designed for manufacturers to meet or exceed a set of minimum requirements.
