The Teltonika TSW304 is a compact, industrial-grade unmanaged Ethernet switch designed for challenging environments and industrial applications. Featuring 4 Gigabit RJ45 ports supporting 10/100/1000 Mbps speeds with Auto MDI/MDIX, this switch ensures reliable high-speed network connectivity.

Built with a shock-resistant aluminium housing and an integrated DIN-rail bracket, the TSW304 offers easy and secure installation in control cabinets and harsh industrial conditions. It supports a wide power input range (7–57 VDC and 9–40 VAC) via a 2-pin industrial power socket, with optional passive PoE input via ETH1 (Mode B, 9–30 VDC), although it is not compatible with IEEE 802.3af/at/bt PoE standards.

Performance highlights include an 8 Gbps non-blocking bandwidth, a 128 KB packet buffer, support for jumbo frames up to 9216 bytes, and a MAC address table that can store up to 2K entries. It complies with IEEE 802.3 standards (802.3i, 802.3u, 802.3ab, 802.3x, 802.3az) ensuring stability and interoperability.

The switch operates efficiently with a low power consumption (Idle 0.26 W, Max 1.44 W) and withstands wide temperature ranges from -40 °C to 75 °C, making it ideal for extreme industrial scenarios. It comes with multiple regulatory certifications including CE, REACH, RoHS, WEEE, UKCA, FCC, IC, CB, and RCM.

This product is perfect for industry professionals requiring a reliable, compact, and efficient unmanaged switch for factory automation, building management systems, and other industrial network setups.
