Layer2 24 Ports EN50155 TSN switch
Product Overview

Time Sensitive Networking (TSN) is a set of protocol standards developed by the IEEE 802.1 TSN Task Force. The standard defines a time-sensitive mechanism for Ethernet data transmission that adds certainty and reliability to standard Ethernet by allowing some traffic packets to be forwarded first, clearing lines using gated scheduling mechanisms and bandwidth reservation to guarantee the performance of service traffic in Ethernet to ensure that Ethernet can provide a stable and consistent level of service for the transmission of critical data.
The Aquam8124TSN series is an EN50155 managed industrial Ethernet switch designed specifically for the rail industry, support up to 24 Gigabit ports, support wall-mounting and a wide range of operable temperatures (-40°C~75°C), meeting the requirements of EN50155, EN50121 and other rail industry standards.
The Aquam8124TSN series supports Time Sensitive Network (TSN) features, the current time sensitive network base protocols include: IEEE 802.1AS Time Synchronization, IEEE 802.1Qbv Scheduled Traffic, IEEE802.1Qbu. IEEE802.1Qci, IEEE802.1CB, etc.
PoE model supports 110VDC isolated power supply and up to 8 IEEE802.3at PoE+ ports(IEEE802.3af compatible).
