    EN50155 Industrial Ethernet Switch
    HEST12LM series switches are designed for the backbone communications for the critical on-board train communications. Bridged between multiple and complex industrial networks, HEST12LM switches are designed to ensure that robust and highly efficient network communications are guaranteed for the critical tasks within a train.

    Compliant with IEC61375、EN51055 and EN50121 standards, and working under extreme temperatures (-40°C to +75°C), these highly compactly-designed industrial switches can meet any hazardous environments while providing robust communication requirements for critical applications such as train traction and/or braking command requirements through these reliable devices.

    Support up to 12 10/100BaseT(X) M12 Ethernet ports , and dual-powered by 24-160VDC (type:48VDC/110VDC) power supplies, this line of switches provide a full set of network data management functions such as redundancy recovery, VLAN, QoS, IGMP, Trunking, SNMP, etc., in addition to the hardened M12 connector and IP67 enclosure protection. These devices have an average MTBF of 438,000 hours. They all can be wall-mounted.
