EN50155 Managed PoE Switch with 12FE PoE and 4GE Bypass, M12 connector, IEEE 802.3af/at, IP54, 24VDC



ORing’s TransporterTM series managed PoE Ethernet switches are designed for industrial waterproof applications, such as rolling stock, vehicle, and railway applications.  TPS-W9124GT-M12X-BP2-24V-IP54 is managed Redundant Ring Ethernet switch with 12x10/100Base-T(X) P.S.E. and 4x10/100/1000Base-T(X) ports which is specifically designed for the toughest and fully compliant with EN50155 requirement.  The switch support Ethernet Redundancy protocol, O-Ring (recovery time < 10/30ms over 250 units of connection), O-Chain, MRP*NOTE and MSTP/RSTP/STP (IEEE 802.1s/w/D) can protect your mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology.  TPS-W9124GT-M12X-BP2-24V-IP54 also supports Power over Ethernet, a system to transmit electrical power up to 30 watts, along with data, to remote devices over standard twisted-pair cable in an Ethernet network.  Each TPS-W9124GT-M12X-BP2-24V-IP54 switch has 12x10/100Base-T(X) P.S.E. (Power Sourcing Equipment) ports.  P.S.E. is a device (switch or hub for instance) that will provide power in a PoE connection.  TPS-W9124GT-M12X-BP2-24V-IP54 includes 2 sets of bypass ports that protect the network from failures and Network maintenance by ensuring network integrity during power loss.  And support wide operating temperature from -40oC to 75oC.  TPS-W9124GT-M12X-BP2-24V-IP54 can also be managed centralized and convenient by Open-Vision, Except the Web-based interface, Telnet, and console (CLI) configuration.  Therefore, the switch is one of the most reliable choices for EN50155 waterproof highly-managed Ethernet application.
