Hirschmann BRS40-8TX/4SFP-EEC Managed Industrial Ethernet Switch: P/N 942170-019

12-port Ethernet Switch with Gigabit Uplinks; 8 x 10/100/1000Base-TX RJ45 ports plus 4 x 100/1000Mbit/s SFP fiber ports. BOBCAT TSN-capable, fanless DIN-rail design.

Managed BOBCAT Switching for Industrial Ethernet Networks

The Hirschmann BRS40-8TX/4SFP-EEC (P/N 942170-019) is a 12-port managed industrial Ethernet switch with Gigabit uplinks built for managed DIN-rail network architectures. Its port configuration combines 8 x 10/100/1000Base-TX RJ45 ports plus 4 x 100/1000Mbit/s SFP fiber ports, providing a compact platform for connecting and segmenting industrial Ethernet networks. The fanless design eliminates moving cooling components and supports operation across an extended temperature range of -40 C to +70 C (-40 F to 158 F).

BOBCAT managed switching functions include VLAN segmentation, traffic prioritization, multicast control, link aggregation, and resilient ring protocols. Time-Sensitive Networking support, PTPv2 synchronization, and 802.1AS help coordinate real-time Ethernet traffic, while EtherNet/IP, PROFINET, Modbus TCP, and IEC 61850 profiles simplify integration with industrial automation systems. Dual 12 - 24V DC power inputs and 11 W power consumption support efficient control-panel deployment.
