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.
This device supports Power over Ethernet (PoE) which describes any of several standardised or ad-hoc systems which pass electrical power along with data on Ethernet cabling.
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.
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 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.
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 come with a standard five year manufacturer warranty.

TN-4528A-16PoE-4GPoE overview

  • 24x fast Ethernet ports (16x with PoE)
  • 4x Gigabit ports with PoE
  • Provides up to 30 watts per PoE port
  • Essential compliance with EN 50155 rail certification
  • Turbo Ring and Turbo Chain (recovery time <20ms @ 250 switches)
  • STP/RSTP/MSTP for network redundancy
  • Up to 20 IEEE 802.3at/af compliant combo PoE and Ethernet ports
  • Isolated power with wide 24 to 110 VDC power supply range
  • Extended -40°C to +75°C operating temperature
The ToughNet TN-4528A-16PoE-4GPoE Series M12 managed Ethernet switches are designed for railway applications, including rolling stock and wayside installations. The switches use M12 and other circular connectors to ensure tight, robust connections, and guarantee reliable operation in industrial environments where vibration and shock are commonplace.

TN-4528A-16PoE-4GPoE Series Ethernet switches provide 24x fast Ethernet M12 ports, 16 of those with IEEE 802.3at/af compliant PoE (Power-over-Ethernet) function and 4x Gigabit Ethernet interface with PoE function and with optional bypass relay. The PoE switches are classified as power source equipment (PSE); they provide up to 30 watts of power per port, and can be used to power IEEE 802.3at/af compliant powered devices (PDs), such as IP cameras, wireless access points and IP phones.

The 24V to 110V DC wide power input range and isolated dual power inputs not only allow you to use the same type of power source at different sites around the globe, but also increase the reliability of your communications system. Furthermore, the extended -40°C to +75°C operating temperature and rugged IP42-rated enclosure allow deployment in harsh environments.

The TN-4528A-16PoE-4GPoE Series Ethernet switches are compliant with essential sections of EN 50155, covering operating temperature, power input voltage, surge, ESD, and vibration, as well as conformal coating and power insulation, making the switches suitable for a variety of industrial applications.
