The Hirschmann BOBCAT BRS20-4TX/2FX-EEC-HL is the widest-capability compact fiber switch in the BOBCAT family, combining ISA12.12.01 hazardous location certification, -40 to +70°C extended temperature operation, 4x 10/100BASE-TX RJ45 copper ports, and 2x 100BASE-FX multimode SC fiber uplinks in a single 57 mm wide fanless DIN rail unit. Manufactured by Hirschmann, a Belden brand, it is designed specifically for Ex-classified zones in oil and gas processing, offshore drilling and production platforms, petrochemical facilities, and chemical plants where both hazardous area approval and long-distance fiber connectivity are required at field network edge positions. The two multimode fiber uplinks support 50/125 µm fiber to 5,000 m and 62.5/125 µm fiber to 4,000 m, enabling inter-unit backbone connections across large process facilities without the need for separate media converters. TSN 802.1Qbv on interfaces 1/1 to 1/3 delivers deterministic real-time Ethernet scheduling, and the full industrial protocol suite — PROFINET, EtherNet/IP, Modbus TCP, IEC61850 — ensures compatibility with DCS, PLC, and SCADA platforms across the process industries. Redundancy spans HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP, LACP, Link Backup, and Redundant Network Coupling. Security features include Secure Boot, signed firmware, 802.1X, RADIUS, VLAN-based ACLs, and DoS prevention. Vibration and shock ratings per IEC 60068-2-6 and IEC 60068-2-27, an MTBF of approximately 2.64 million hours, and a 60-month guarantee confirm its suitability for demanding long-lifecycle process industry field deployments.
