The PLANET TSN-5225-4T2S is a rugged industrial Layer 2+ managed Ethernet switch with built-in Time-Sensitive Networking (TSN) technologies, engineered to deliver ultra-low latency and deterministic communication in time-critical environments. Featuring four Gigabit RJ45 ports and two dual-speed 1G/2.5G SFP ports, it offers flexible fiber extension and high-precision synchronization for industrial automation, 5G, AIoT, and smart manufacturing.

Designed for -40 to 75°C environments, with redundant power input, IP30 aluminum enclosure, and support for key TSN IEEE standards (802.1AS-Rev, Qbv, Qci, Qbu, CB), it integrates seamlessly with real-time systems. The switch also supports IEEE 1588v2 PTP, ensuring synchronization down to the microsecond.

It includes advanced Layer 2/3 functionalities, VLAN-based routing, ACL security, QoS, Modbus TCP, and remote management through PLANET UNI-NMS/NMSViewerPro. Digital input/output (DI/DO) terminals allow integration into alarm systems, while the SFP-DDM function facilitates real-time monitoring of optical transceivers.
