BRS40-20TX/4SFP – All-Gigabit TSN Managed DIN Rail Switch by Hirschmann

The Hirschmann BOBCAT BRS40-20TX/4SFP is a high-port-density all-Gigabit managed industrial switch offering 24 ports in total across 20 x 10/100/1000BASE-TX RJ45 copper connections and four SFP slots supporting 100 or 1000 Mbit/s fiber modules. Part number 942170067, this DIN Rail-mounted switch is part of Hirschmann’s BOBCAT TSN series and supports IEEE 802.1Qbv Time-Sensitive Networking for deterministic, real-time Ethernet communication across industrial control and automation backbones. The SFP uplink slots are compatible with single-mode, long-haul, and multimode fiber transceivers, providing the flexibility to span large manufacturing plants, campus networks, or geographically dispersed sites. Redundancy features include HIPER-Ring, MRP (IEC62439-2) as both client and manager, RSTP with guards, and Link Aggregation with LACP to ensure continuous network operation. Industrial protocol support covers PROFINET, EtherNet/IP, IEC61850 MMS Server, and Modbus TCP. The security suite includes 802.1X port-based access control, RADIUS client and VLAN assignment, secure boot, signed firmware, VLAN-based ACL, and comprehensive DoS prevention. The fanless PC-ABS housing operates from 0 to +60°C and consumes 19 W from dual redundant 12–24 VDC power inputs. USB-C, HTML5 web management, CLI, and SNMP v1/v2/v3 provide full management flexibility. The BRS40-20TX/4SFP is well suited to larger automation cells, multi-zone factory networks, energy distribution, and process industries where maximum port count and fiber uplink flexibility are equally important.
