EKI-2525 - 5 Port 10/100BaseTX Unmanaged Industrial Ethernet Switch

5 Year Warranty

These products come with a standard five year manufacturer warranty.


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.

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.


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.

The EKI-2525 is an industrial grade five port unmanaged Ethernet switch from Advantech. Enclosed in a rugged and durable IP30 rated metal enclosure, the EKI-2525 is ideal for harsh and heavy industrial networking applications.

Each Ethernet port supports 10/100Mbps transmission speeds and features broadcast storm protection which helps keep the Ethernet network at optimum performance.

The EKI-2525 features a dual 12V to 48V DC power input with a redundancy failover feature. In the case that the main power supply fails, the secondary power supply will kick in automatically with minimal disruption. The EKI-2525 is also protected from reverse polarity and overload current, which is often a common problem with generator based power source.

Unlike cheaper commercial Ethernet switches, the EKI-2525 is designed to operate in heavy industrial applications. As such, the EKI-2525 will operate in a -10°C to +60°C wide or -40°C to +75°C extended temperature range and 5% to 95% non-condensing humidity range.

In terms of certification, the EKI-2525 is UL 60950-1 and Class 1 Division 2 certified for use in hazardous locations, such as petrochemical plants and mines. As most of the environments the EKI-2525 is installed in, the EKI-2525 meets the IEC 60068-2 standard in terms of vibration, shock and freefall.

Measuring in at just W27mm x H140mm x D95mm the EKI-2525 features a DIN-rail mounting bracket, allowing it to be easily integrated into control boxes and cabinets.

Finally, the EKI-2525 is backed by a long-term industry leading five year Advantech warranty.

Impulse is a leading UK supplier and integrator of high quality industrial grade Ethernet switches and communication products.
