The Hirschmann BOBCAT BRS20-4TX/2FX is a 6-port managed industrial Fast Ethernet switch from Hirschmann, a Belden brand, designed for industrial automation and process control networks that require both local copper connectivity and multimode fiber uplink capability in the smallest possible DIN rail footprint. The switch provides 4x 10/100BASE-TX RJ45 copper ports alongside two 100BASE-FX multimode SC fiber uplinks, supporting 50/125 µm fiber to 5,000 m and 62.5/125 µm fiber to 4,000 m, making it well suited to inter-cabinet and inter-building connections across manufacturing facilities, substations, and process plants without the need for additional media converters or fiber switches. At just 57 mm wide, fanless, and with dual redundant 12 to 24 VDC power inputs and USB-C local management, the BRS20-4TX/2FX is designed for space-constrained DIN rail panel positions where fiber backbone connectivity must be maintained alongside local copper switching. TSN 802.1Qbv support on interfaces 1/1 to 1/3 provides deterministic real-time Ethernet performance, and the full redundancy suite — HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP, LACP, Link Backup, and Redundant Network Coupling — enables participation in high-availability ring and star topologies spanning copper and fiber segments. PROFINET, EtherNet/IP, Modbus TCP, and IEC61850 industrial protocol support ensures compatibility with major PLC, SCADA, and protection relay platforms. Security is addressed through Secure Boot, signed firmware, 802.1X, RADIUS, VLAN-based ACLs, and DoS prevention. PTPv2 boundary and transparent clock support ensures precise time synchronisation across the automation network. With an MTBF of approximately 2.64 million hours and a 60-month guarantee, the BRS20-4TX/2FX is a reliable compact fiber-capable switch for long-lifecycle industrial deployments.
