EN50155 Industrial Ethernet Layer 3 Switch
HEST12LM switches are designed for the backbone communications for the critical onboard train communications across different networks. Bridged between multiple and complex industrial networks, HEST12LM switches are designed to ensure that robust and highly efficient network communications are guarantees 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-de-signed 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 10/100BeseT(X) M12 Ethernet ports, and dual-powered by 18-160VDC power supplies,this line of switches provides a full set of Layer 3 network data management functions such as redundancy recovery, RIP, OSPF, NAT, ACL, etc.,in add 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.
