The Hirschmann BOBCAT BRS20-12TX is a managed industrial Fast Ethernet switch built for real-time communication in automation and control environments. Developed by Hirschmann, a Belden brand with a long track record in industrial networking, this compact switch brings Time-Sensitive Networking (TSN 802.1Qbv) to the DIN rail form factor, enabling deterministic traffic scheduling across interfaces 1/1 to 1/3 without hardware changes. The switch provides 12x 10/100BASE-TX RJ45 ports, dual redundant 12 to 24 VDC power inputs, and a USB-C port for local management and device replacement. Its fanless construction and IP30-rated PC-ABS housing make it suitable for panel and cabinet installation in space-constrained industrial environments operating between 0 and +60°C. For network resilience, the BRS20-12TX supports HIPER-Ring, Media Redundancy Protocol (MRP) per IEC62439-2, RSTP, Link Aggregation with LACP, and Redundant Network Coupling. Industrial protocol support spans PROFINET, EtherNet/IP, Modbus TCP, and IEC61850, making it directly compatible with leading PLC and SCADA platforms used in manufacturing, energy, and process industries. Security features include 802.1X port-based access control, RADIUS authentication, Secure Boot, signed firmware images, VLAN-based ACLs, and DoS prevention, meeting the cybersecurity requirements of modern OT networks. Management is handled via HTML5-based web interface, CLI, SNMP v1/v2/v3, SSHv2, HTTPS, and IPv6, with PTPv2 boundary and transparent clock support for precise time synchronisation. With an MTBF exceeding 3 million hours and a 60-month guarantee, the BRS20-12TX is engineered for long-term reliability in industrial automation, machine control, smart grid, and building automation applications.
