The Hirschmann BOBCAT BRS40-20TX-EEC is a fully managed all-Gigabit industrial Ethernet switch providing 20 x 10/100/1000BASE-TX RJ45 ports in a compact DIN Rail package, specifically engineered for deployment in environments operating from -40 to +70°C. Part number 942170090, this all-copper port configuration is ideal for high-density edge switching applications where fiber uplinks are not required and where cost-effective, all-Gigabit copper connectivity must be maintained across extreme temperature ranges. The BRS40-20TX-EEC is part of the Hirschmann BOBCAT series, which was the first switch family to introduce Time-Sensitive Networking support via IEEE 802.1Qbv, enabling real-time deterministic communication over standard Ethernet without additional hardware investment. Its industrial protocol suite includes PROFINET, EtherNet/IP, IEC61850, and Modbus TCP, ensuring broad compatibility with major automation platforms. Redundancy options span HIPER-Ring, MRP (IEC62439-2), RSTP, and LACP, while the security architecture covers 802.1X, RADIUS authentication, secure boot, signed firmware, VLAN-based ACL, and DoS prevention. The metal housing delivers robust EMC and mechanical protection, rated to IP30. Power is supplied via dual redundant 12–24 VDC inputs at just 17 W consumption. USB-C management support, HTML5 web GUI, CLI scripting, and SNMP v1/v2/v3 provide comprehensive remote and local management capabilities. Suited to outdoor substations, railway applications, cold storage automation, and heavy process industries, the BRS40-20TX-EEC delivers proven Hirschmann reliability where temperatures are never moderate.
