Managed Fast Ethernet Hirschmann BRS20-4TX: 4-Port Managed Industrial Fast Ethernet Switch
DIN-rail BOBCAT series switch with 4 x 10/100Base-TX RJ45 ports, fanless PC-ABS housing, TSN-ready platform support, and redundant 12–24VDC power input.

✓ 4-Port Managed Industrial Ethernet Switch for Machine Networks

Part Number: 942170-001 | Vendor Part Number: 942170001 | Series: Hirschmann BOBCAT BRS20

Overview

The Hirschmann BRS20-4TX is a compact managed industrial Fast Ethernet switch built for machine-level networks, control panels, and automation systems that need reliable copper Ethernet connectivity. It provides 4 x 10/100Base-TX RJ45 ports in a fanless DIN-rail housing and uses the BOBCAT platform for modern industrial network management.4 RJ45 PortsDIN RailIP30

This switch is designed for industrial Ethernet segments where PLCs, HMIs, remote I/O, drives, and smart devices need managed traffic control. Redundant power input, USB-C local management, industrial protocol support, and built-in diagnostics help reduce downtime while keeping cabinet networks organized and easier to service.

💡 Managed Network Control

Industrial Switching: Supports VLANs, QoS, multicast handling, flow control, and traffic prioritization for deterministic automation networks.

Redundancy Support: Includes HIPER-Ring, MRP, RSTP, LACP, link backup, and redundant network coupling for resilient plant-floor communication.

Secure Management: Includes HTTPS, SSHv2, SNMP v1/v2/v3, local user management, RADIUS authentication, and IEC 62443-4-2 security certification.

Key Features

  • 4 x 10/100Base-TX RJ45 ports: copper Fast Ethernet connectivity for industrial devices
  • Managed switch functionality: VLAN, QoS, multicast, prioritization, and monitoring tools
  • Fanless BOBCAT design: compact PC-ABS housing for control cabinet installation
  • Redundant 12–24VDC power input: dual supply capability for improved uptime
  • USB-C local management: supports local access and device replacement workflows
  • Digital input and signal contact: terminal block connections for monitoring and status integration
  • Industrial protocol support: EtherNet/IP, PROFINET, Modbus TCP, and IEC61850
  • Advanced diagnostics: LEDs, syslog, RMON, port mirroring, cable test, TCPDump, and link monitoring
  • Security hardened: ISASecure CSA / IEC 62443-4-2 certified feature set
  • 5-year manufacturer guarantee: backed by Hirschmann for long-term industrial use

✅ Why Choose This Switch?

The BRS20-4TX gives smaller machine networks managed switch features without taking up the space of a larger multi-port unit. It is a strong fit when a cabinet needs traffic segmentation, redundancy, remote diagnostics, and industrial protocol support in a compact 4-port format.

Applications

Use the Hirschmann BRS20-4TX to manage Ethernet connections close to the machine, inside control cabinets, or at smaller network aggregation points where unmanaged switching does not provide enough visibility or control.

  • PLC, HMI, and remote I/O Ethernet connections
  • Machine-level PROFINET or EtherNet/IP network segments
  • Industrial automation panels that need VLANs, QoS, and diagnostics
  • Small cabinet networks requiring redundant paths or link backup
  • Plant-floor device monitoring through SNMP, syslog, LEDs, and port mirroring
