The Teltonika TSW040 is a robust, unmanaged 8-port PoE+ Ethernet switch tailored for industrial and harsh environment applications. It offers eight PoE-out RJ45 ports compliant with IEEE 802.3af and 802.3at standards, delivering up to 30 W per port and a total PoE power budget of 240 W. With support for 10/100 Mbps speeds and auto MDI/MDIX crossover, this switch ensures reliable, plug-and-play connectivity without complex configuration.

Designed for flexibility and durability, the TSW040 features an integrated DIN rail mounting bracket for easy industrial installation. It supports a wide input voltage range of 7–57 VDC (and 44–57 VDC for PoE operation) with overvoltage and reverse polarity protection, powered via a 2-pin industrial DC input connector.

Constructed from anodized aluminum, the device measures 113.1 x 41.2 x 74.6 mm and weighs 280 g, making it compact yet sturdy. Its operating temperature range of -40 °C to 75 °C and IP30 ingress protection rating ensure reliability in demanding environments. Key network specifications include a non-blocking bandwidth of 20 Gbps, 128 KB packet buffer, 2K MAC address table, and support for jumbo frames up to 9216 bytes.

Additional features include status LEDs for power and Ethernet ports, a grounding screw for enhanced safety, and optional wall/flat surface mounting kits. The TSW040 is ideal for industrial automation, surveillance systems, and network extension where stable PoE power and robust connectivity are critical.
