The Hirschmann BOBCAT BRS20-4TX is the entry-level port-count variant of Hirschmann’s TSN-capable managed industrial Fast Ethernet switch family, offering 4x 10/100BASE-TX RJ45 ports in an ultra-compact 57 mm wide fanless DIN rail housing that is ideal for space-constrained control panels, machine-mounted cabinets, and distributed field enclosures. Developed by Hirschmann, a Belden brand, the BRS20-4TX shares the full BOBCAT software and security feature set with larger variants, making it a genuine managed switch solution rather than a cut-down entry product. TSN 802.1Qbv support across interfaces 1/1 to 1/3 brings deterministic real-time Ethernet scheduling to small-footprint nodes within larger industrial automation and IIoT networks. Dual redundant 12 to 24 VDC power inputs, USB-C local management, and IP30-rated PC-ABS housing round out a practical, low-power design consuming just 5 W. Redundancy capabilities span HIPER-Ring, MRP (IEC62439-2) as client and manager, RSTP, LACP Link Aggregation, Link Backup, and Redundant Network Coupling, enabling this compact switch to participate fully in ring and star high-availability topologies. PROFINET, EtherNet/IP, Modbus TCP, and IEC61850 protocol support ensures direct integration with PLCs, SCADA platforms, and protection relays across manufacturing, energy, and process industries. Security features include Secure Boot, signed firmware, 802.1X port access control, RADIUS authentication, VLAN-based ACLs, and DoS prevention. An exceptional MTBF of over 5.8 million hours and a 60-month guarantee make the BRS20-4TX one of the most reliable switches in the BOBCAT family, suited to long-lifecycle deployments where compactness and dependability are equally important.
