Urban rail transit system as the principal part of future urban traffic has a large carrying capacity, running on time, fast running speed, low tariff, no pollution, and a series of superior characteristics. With the development of Chinese economy, the speeding up of urbanization, the rapid development of urban traffic reasonably, especially rail transit has gradually become the key of the major large and medium-sized cities to solve the traffic problems.

In order to further meet and guarantee the needs of rail transit industry network communication, 3onedata has launched EN50155 series industrial Ethernet switch specially researched and designed for rail transit industry- layer 3 managed industrial POE switches TNS5812-4GT-8POE and layer 2 managed industrial POE switches TNS5512-4GT-8POE.

This series of products fully meet the requirements of rail transit industry EN50155 standards, support 12 M12 Ethernet ports, effectively guarantee the sealing and firmness of port connections, especially suitable for strong vibration and shock application scenarios, which can be widely used in automotive PIS, CCTV, video monitoring system, train control system, can provide a stable, efficient and reliable communication solution for train automation system.

3onedata EN50155 series industrial Ethernet switches is highly favored by industry users for its stable excellent performance and price advantage , has been fully applied to all over the country, including Beijing, Shanghai, Shenzhen metro trains PIS system. It also won the CRTS selection of  “2015 China rail transit industry top ten industrial Ethernet switches”, 2015-2016 14th annual selection of automation “innovation award” and many other industry awards.
