The Hirschmann BOBCAT BRS20-16TX/4SFP is a 20-port managed industrial Fast Ethernet switch from Hirschmann, a Belden brand, designed for industrial automation networks that require both dense copper port connectivity and flexible fiber uplink capability in a single compact DIN rail unit. The switch provides 16x 10/100BASE-TX RJ45 ports alongside four 100 Mbit/s SFP slots arranged as two dual-SFP uplink groups, supporting single-mode, long-haul single-mode, and multimode fiber types, enabling long-distance inter-cabinet or inter-building connections without the need for additional media converters. Operating from 0 to +60°C with dual redundant 12 to 24 VDC power inputs, a fanless PC-ABS DIN rail housing, and USB-C local management, the BRS20-16TX/4SFP is suited to machine builders, panel integrators, and OEM automation system designers who need fiber backbone capability within a space-constrained cabinet. TSN 802.1Qbv support on interfaces 1/1 to 1/3 delivers deterministic traffic scheduling for real-time control applications, while the full redundancy suite — HIPER-Ring, MRP (IEC62439-2) as client and manager, RSTP, LACP, Link Backup, and Redundant Network Coupling — ensures network resilience in ring and star topologies. Industrial protocol support for PROFINET, EtherNet/IP, Modbus TCP, and IEC61850 makes the switch directly compatible with major PLC, SCADA, and protection relay ecosystems across manufacturing, energy, and process sectors. Security capabilities include Secure Boot, signed firmware, 802.1X, RADIUS, VLAN-based ACLs, and DoS prevention, delivering OT cybersecurity appropriate to modern industrial networks. PTPv2 boundary and transparent clock support enables precise time synchronisation across the automation network. With an MTBF of approximately 2.97 million hours and a 60-month guarantee, the BRS20-16TX/4SFP provides long-term reliability in demanding industrial applications.
