HEST12M

Series05563ds - 2/3

©2016 Henrich Corporation. All rights reserved

HEST12M series switches are designed for communications between machines/devices inside trains. Compliant with IEC61375

standard and EN51055, 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.
