Industrial Network Connectivity and ControlThe Hirschmann BRS30-24TX-EEC (part number 942170-088) is a 24-port managed industrial Ethernet switch in the BRS BOBCAT series. It combines 20 10/100BASE-TX RJ45 ports with four 10/100/1000BASE-TX RJ45 ports, providing Fast Ethernet device connections and Gigabit uplinks in one switch. The fanless design and metal housing support DIN rail installation in industrial network systems. Time-Sensitive Networking (TSN) supports real-time communication. Managed switching functions provide VLAN segmentation and traffic prioritization, while network diagnostics and access controls support network administration. The operating temperature range is -40 °C to +70 °C (-40 °F to 158 °F). This extended temperature range suits installations exposed to wider ambient temperature changes. A five-year manufacturer’s guarantee applies. Features and Benefits- 20 Fast Ethernet ports and four Gigabit-capable RJ45 ports for mixed-speed networks.
- Time-Sensitive Networking (TSN) for real-time communication.
- Fanless construction for operation without a cooling fan.
- Metal housing with DIN rail mounting.
- VLAN and QoS functions for network segmentation and traffic prioritization.
- USB-C for local management and device replacement.
- Extended operating temperature range of −40 °C to +70 °C.
Applications and Recommended UsesRecommended uses include automation cells that combine Fast Ethernet device connections with Gigabit uplinks. This port arrangement supports local machine communications while providing higher-speed connections to other switches or supervisory systems. - Machine control panels connecting PLCs, HMIs, drives, and remote I/O over 10/100 Ethernet.
- Packaging or assembly lines that connect local control devices to a Gigabit plant network.
- Material handling systems linking conveyor control equipment through managed Ethernet.
- Production cells requiring VLAN segmentation and prioritized control traffic.
The −40 °C to +70 °C operating range makes this variant a candidate for enclosed automation installations with wider ambient temperature changes. Match the installation to the switch’s IP30 protection rating and specified humidity limits. Installation and Network PlanningAllow space for the switch dimensions and the required cable connections when planning the DIN rail layout. Use the specified 12–24 V DC power inputs and keep the installation within the operating temperature and humidity limits. Twisted-pair connections support cable lengths up to 100 m. Review the BOBCAT series manual for wiring, configuration, and installation requirements before commissioning the network. Technical Specifications| Manufacturer | Hirschmann |
