Overview

The Hirschmann BOBCAT BRS20-12TX-EEC is the extended temperature variant of Hirschmann’s TSN-capable managed industrial switch, designed for deployment in environments where thermal extremes, vibration, and electrical interference are daily challenges. Manufactured by Hirschmann, a Belden brand, this DIN rail switch supports an operating temperature range of -40 to +70°C, making it suited to outdoor infrastructure, rolling stock, wind energy, and heavy industrial plant installations across Nordic and Baltic climates. The switch features 12x 10/100BASE-TX RJ45 ports, dual redundant 12 to 24 VDC power inputs, and USB-C local management, all within a compact fanless PC-ABS housing rated to IP30. Time-Sensitive Networking (TSN 802.1Qbv) support across interfaces 1/1 to 1/3 delivers the deterministic latency control needed in motion control and process automation systems. Redundancy is covered comprehensively through HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP, Link Aggregation with LACP, Link Backup, and Redundant Network Coupling. Industrial protocol support for PROFINET, EtherNet/IP, Modbus TCP, and IEC61850 ensures compatibility across PLC, SCADA, and protection relay ecosystems. The BRS20-12TX-EEC also meets rigorous cybersecurity requirements with 802.1X port-based access control, RADIUS authentication, Secure Boot, signed firmware images, VLAN-based ACLs, and DoS prevention. Management options span HTML5 web GUI, CLI, SNMP v1/v2/v3, SSHv2, HTTPS, and IPv6, with PTPv2 boundary and transparent clock for precision timing. Vibration and shock resistance per IEC 60068-2-6 and IEC 60068-2-27 further qualify this switch for transportation and mobile plant applications. With an MTBF of over 3 million hours and a 60-month guarantee, it delivers long-term reliability in the most demanding field environments.
