Teltonika TSW040 Industrial Switch – 8-Port PoE+ Professional

The Teltonika TSW040 is an 8-port industrial unmanaged PoE+ switch designed for industrial automation applications, manufacturing facilities, and technical environments where connection reliability and PoE power delivery to field devices are baseline operational requirements. It is deployed on production lines, OT infrastructures, and industrial installations where the switch must operate continuously under extreme temperature conditions, vibration, and power supply fluctuations without manual intervention.

Each of the 8 RJ45 ports supports up to 30 W PoE+, with a total PoE budget of 240 W — sufficient to simultaneously power IP cameras, wireless access points, industrial controllers, and field sensors without additional power supplies. Non-blocking switching bandwidth of 20 Gbps, a 128 KB packet buffer, and jumbo frame support up to 9216 bytes ensure lossless data transmission and minimal latency under full load. The 2,000-entry MAC address table covers mid-complexity industrial network segments without degrading switching performance.

The 2-pin industrial power input accepts 7–57 VDC and includes protection against overvoltage, reverse polarity, and current spikes — essential in environments with unstable power sources and high electromagnetic interference. Native DIN rail mounting enables rapid integration into electrical panels and automation cabinets, with additional options for wall or flat surface mounting. The anodized aluminum enclosure with IP30 protection withstands operating temperatures from -40 °C to +75 °C and humidity up to 95% non-condensing.

Recommended for automation engineers and OT integrators equipping production lines, industrial facilities, and field infrastructures with compact and robust PoE+ Ethernet connectivity. It suits projects where plug-and-play operation and zero software configuration reduce commissioning time, and where optional Profinet Class A support ensures compatibility with Siemens automation ecosystems and other standardized industrial platforms.
