BRS40-24TX – All-Gigabit TSN Managed DIN Rail Switch by Hirschmann, a Belden Brand

The Hirschmann BOBCAT BRS40-24TX is a high-density all-copper managed Gigabit industrial switch providing 24 x 10/100/1000BASE-TX RJ45 ports in a compact DIN Rail enclosure weighing just 1160 g. Part number 942170091, it is designed for industrial applications where maximum copper port count and all-Gigabit throughput are the primary requirements and where fiber uplinks are handled elsewhere in the network architecture. As part of the Hirschmann BOBCAT series, the BRS40-24TX supports IEEE 802.1Qbv Time-Sensitive Networking, enabling real-time deterministic traffic scheduling on standard Ethernet infrastructure — a critical capability for modern IIoT and Industry 4.0 automation deployments. The comprehensive software stack covers HIPER-Ring and MRP (IEC62439-2) ring redundancy, RSTP, LACP link aggregation, IGMP snooping per VLAN, QoS prioritization via 802.1D/p and TOS/DSCP, and full VLAN management. Industrial protocol support spans PROFINET, EtherNet/IP, IEC61850, and Modbus TCP. Security features include 802.1X port-based access control, RADIUS authentication and VLAN assignment, secure boot, signed firmware, and DoS prevention with drop counters. The fanless PC-ABS housing operates from 0 to +60°C with IP30 protection, powered from dual redundant 12–24 VDC inputs at 19 W. USB-C enables local management and AutoConfiguration Adapter-based device replacement, complemented by HTML5 web GUI, CLI, and SNMP v1/v2/v3. The BRS40-24TX is the right choice for engineers needing the highest copper port density in the BOBCAT family for dense automation panels, machine cabinets, and multi-device process control networks.
