Hirschmann BRS50-16TX/4SFP BOBCAT Managed Industrial Ethernet Switch: 20 Ports
DIN-rail managed industrial gigabit ethernet switch with 16 × 10/100/1000Base-TX RJ45 + 4 × 100/1000/2500 Mbit/s SFP, fanless operation, Time-Sensitive Networking support, redundant 12-24V DC power inputs, and a 5-year manufacturer's guarantee.
Managed Connectivity for Real-Time Industrial Networks
The Hirschmann BRS50-16TX/4SFP (part number 942170-069) is a 20-port BOBCAT managed industrial Ethernet switch designed for DIN-rail automation networks. Its fanless pc-abs housing combines 16 × 10/100/1000Base-TX RJ45 + 4 × 100/1000/2500 Mbit/s SFP in a compact platform for connecting PLCs, controllers, HMIs, drives, remote I/O, and other Ethernet-enabled equipment.
BOBCAT switching features support deterministic communication, resilient network design, and controlled traffic flow. Time-Sensitive Networking, VLANs, Quality of Service, HIPER-Ring, MRP, RSTP, industrial protocol profiles, and extensive diagnostic tools help engineers build and maintain reliable machine and plant networks. Its standard operating range supports installations from 0°C to +60°C (32°F to 140°F).
🔌 20 Managed Ports

⏱️ TSN & Precision Timing
Time-Sensitive Networking, PTPv2, 802.1AS, and SNTP support synchronized real-time communication
🔁 Network Redundancy
HIPER-Ring, MRP, RSTP, link aggregation, link backup, and redundant network coupling
🌡️ Industrial Temperature
0 C to +60 C (32 F to 140 F) operating range with fanless cooling
Key Features & Benefits
- Application-Focused Port Layout: Four fiber SFP ports supporting speeds up to 2.5 Gigabit for the bandwidth and media needs of this BOBCAT configuration
- Deterministic Communication: TSN and precision time-synchronization functions support coordinated industrial processes and time-sensitive data
- Resilient Network Design: Multiple ring, spanning-tree, link-backup, and aggregation options help maintain communications after a link interruption
- Traffic Segmentation: VLAN, multicast, QoS, queue management, storm protection, and flow-control tools help separate and prioritize network traffic
- Industrial Protocol Support: Profiles include EtherNet/IP, IEC 61850, Modbus TCP, and PROFINET for integration across automation systems
- Layered Security: IEC 62443-4-2 certification, 802.1X access control, RADIUS, ACLs, HTTPS, password policies, and user-management functions help protect network access
- Service and Diagnostics: USB-C management, port monitoring, cable testing, event logging, RMON, port mirroring, and SFP management simplify troubleshooting
- Fanless Operation: Eliminates a common mechanical wear component and supports quiet, low-maintenance panel installation
⚠️ SFP Transceivers Sold Separately
The four SFP ports require compatible fiber transceivers, which are not included. Select SFP modules for the required fiber type, transmission distance, and data rate. Review the detailed cable-length specifications and confirm module compatibility before ordering.
⚡ Power & Installation Notes
Redundant power: The switch accepts two 12-24V DC power inputs through a plug-in terminal block.
Panel mounting: Install on a DIN rail inside an enclosure appropriate for the IP30 protection class and the surrounding environment.
Management and replacement: A USB-C interface supports local management and device-replacement workflows.
