The Hirschmann BOBCAT BRS20-4TX/2FX-SM-EEC-HL represents the most demanding specification point in Hirschmann’s compact BOBCAT fiber switch family, combining ISA12.12.01 hazardous location certification, -40 to +70°C extended temperature operation, and two 100BASE-FX single-mode SC fiber uplinks with a reach of up to 32.5 km on 9/125 µm fiber — all within a 57 mm wide fanless PC-ABS DIN rail housing rated to IP30. Manufactured by Hirschmann, a Belden brand, this switch is designed specifically for Ex-classified zones in oil and gas processing facilities, offshore drilling and production platforms, petrochemical plants, and remote outdoor energy infrastructure where thermal extremes, hazardous area classification, and long inter-site fiber spans must all be addressed simultaneously from a single compact field network node. At just 7 W consumption, the switch suits energy-constrained Ex-zone panel installations where heat generation is a design constraint. Four 10/100BASE-TX RJ45 copper ports alongside the two long-reach single-mode fiber uplinks are managed via USB-C, with dual redundant 12 to 24 VDC power inputs ensuring supply resilience. TSN 802.1Qbv on interfaces 1/1 to 1/3 delivers deterministic real-time Ethernet scheduling, while the full industrial protocol suite — PROFINET, EtherNet/IP, Modbus TCP, IEC61850 — ensures compatibility with DCS, PLC, and SCADA platforms across the process industries. Redundancy features span HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP, LACP, Link Backup, and Redundant Network Coupling. Security includes Secure Boot, signed firmware, 802.1X, RADIUS, VLAN-based ACLs, and DoS prevention. Vibration and shock compliance per IEC 60068-2-6 and IEC 60068-2-27, an MTBF of approximately 2.64 million hours, and a 60-month guarantee confirm suitability for long-lifecycle harsh-environment process industry deployments.
