The TSN3220-10S-U features 8x 10/100/1000BASE-T PoE++ ports, 2x 1/10Gb SFP+ ports, designed especially for real-time industrial networks where predictable latency and bounded jitter are essential. As a Layer 2 TSN switch supporting IEEE 802.1AS, IEEE 802.1Qbv, and IEEE 802.1Qcc, together with IEEE 1588v2 PTP and SyncE, it enables precise time synchronization and predictable traffic behavior across the network, making it ideal for time-critical applications such as smart manufacturing, 5G convergence, and autonomous systems. The switch delivers up to 60W per PoE++ port with a total power budget of 360W, enabling stable power supply to high-demand devices such as IP cameras, robotic arms, and CNC lathes, while also simplifying cabling and reducing deployment costs. With an IP41-rated metal case, the switch can operate stably in harsh environments ranging from -40 to 75°C.
