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.

2 Year Warranty

These products come with a standard two year manufacturer warranty.

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.

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.

The ADAM-6520 is a 5-port industrial-grade switch with Ethernet connectivity with 10Mbps to 100Mbps transfer rates (auto-negotiation). Just like any other product in the ADAM family, the ADAM-6520 can be mounted in three different ways, DIN rail, wall and stack.

Solid industrial-grade design assures reliable operation in common application areas like semi-conductor factories, inventory control environments, assembly lines, manufacturing and many more. All modules support a wide voltage range of +10V to +30V DC over the terminal block, and 3000V DC surge (EFT) protection ensures that over-voltage is of no concern.

The wide operating temperature of the ADAM-6520 is from -10°C to +70°C which permits them to be functional in harsh environments. The six inclusive LED indicators make troubleshooting of the modules easier. Each port has a pair of LEDs that indicate link status and port activities. This easily informs users of any collisions, the link status, power failure and data receipts for immediate on-site diagnosis.

Impulse is a leading UK distributor of Advantech products and can supply you the ADAM-4018+ along with a wide range of industrial computing and communication products.
