The Teltonika TSW304 Ethernet Switch delivers reliable high-speed connectivity in industrial environments. It features four Gigabit Ethernet ports (10/100/1000 Mbps) with auto MDI/MDIX, removing the need for crossover cables and simplifying installation. The switch provides a non-blocking 8 Gbps switching capacity and includes a 128 KB packet buffer, ensuring smooth transmission of data without delays. Jumbo frame support up to 9216 bytes allows efficient handling of large data flows, such as high-resolution video streams, industrial telemetry, or sensor data. Designed according to IEEE 802.3 standards, TSW304 guarantees seamless interoperability with other devices and stable performance under heavy network load. Its reliable design ensures continuous connectivity for critical industrial applications, while its optimized performance allows it to handle significant data traffic efficiently, making it ideal for automation, energy, and industrial networking scenarios.

The TSW304 Ethernet Switch offers reliable power options for diverse industrial applications. It operates on a wide input range of 7–57 V DC or 9–40 V AC through a robust 2-pin industrial connector, ensuring stable operation even during voltage fluctuations in demanding environments. Energy efficiency is excellent, with power consumption of only 0.26 W in idle mode and up to 1.44 W under full load, reducing operational costs while maintaining continuous network performance. The first Ethernet port supports passive PoE Mode B, allowing the switch to receive both power and data over a single cable, simplifying installation. Installation is straightforward thanks to DIN-rail mounting, while optional wall or flat-surface brackets provide additional flexibility. A dedicated grounding screw protects the device from electrical surges, and clearly visible LED indicators for power and Ethernet ports provide instant status feedback. All these features ensure reliable deployment, simple monitoring, and easy maintenance in industrial settings.

The Teltonika TSW304 is designed for durability, making it ideal for industrial installations with limited space. Its full aluminum housing provides robust protection for electronic components and meets IP30 standards, guarding against dust, debris, and accidental contact. Measuring 103 × 34 × 90 mm and weighing approximately 300 g, the switch can be easily installed in tight enclosures, vehicles, or control cabinets without compromising protection. It operates reliably under extreme environmental conditions, with a temperature range of –40 °C to +75 °C and relative humidity tolerance between 10% and 90% without condensation. Certified to international standards including CE, UKCA, FCC, IC, RCM, CB, and EAC, TSW304 is suitable for global deployment and meets strict industrial compliance requirements. Its rugged construction, combined with compact dimensions and wide environmental tolerance, ensures stable, long-term performance. This makes TSW304 an ideal solution for automation, transportation, energy, and various industrial networking applications, where consistent connectivity and durability are essential for efficient operation.
