Teltonika TSW304 - Industrial Unmanaged 4-port Gigabit Ethernet Switch, Black

The Teltonika TSW304000010 is a 4-port industrial unmanaged Gigabit Ethernet switch designed for plug-and-play operation. It expands wired network capacity by adding four RJ45 ports for industrial equipment. Each port supports speeds up to 1000 Mbit/s. As a Layer 2 switch, it forwards traffic automatically between connected nodes, allowing for immediate deployment without the need to assign IP addresses or adjust software settings.

The aluminium housing protects internal components and helps dissipate heat during continuous operation. The black enclosure measures 102 x 81.5 x 25 mm and weighs 210 g. Designed for tight spaces, the switch can be wall-mounted within industrial control cabinets or panels. LAN and power LEDs on the front panel provide a quick status overview. The unit accepts a wide input voltage range—7 to 57 V DC or 9 to 40 V AC—and consumes a maximum of 1.44 W under full load.

• 8 Gbit/s switching capacity for non-blocking data forwarding across all four ports.
• Auto-MDI/MDIX support detects cable types automatically, removing the need for crossover cables.
• 9216-byte jumbo frame support reduces overhead during large file transfers.
• 2000-entry MAC address table for tracking endpoints in isolated control networks.
• 0.128 MB packet buffer memory to prevent data loss during traffic spikes.
• Compliance with IEEE 802.3az Energy Efficient Ethernet to reduce power consumption during low activity.
