Advantech SE208 Unmanaged Industrial Ethernet Switch

The Advantech SE208 is an eight-port unmanaged industrial Ethernet switch designed for rugged automation networks. Eight copper RJ45 ports support auto-negotiation for 10/100/1000BASE-T; the switch uses store-and-forward switching, with a 2K MAC address table and a 448 Kbit packet buffer. A 6-pin removable screw-terminal supplies power and provides an integrated alarm relay interface. The SE208-T variant is offered in a rugged enclosure with IP30 protection and a wide temperature range of -40 to 75°C, while the standard SE208 operates from -10 to 60°C. As a plug-and-play device, it requires no configuration, making it suitable for quick deployments where fixed topology is preferred. It is commonly used to extend Ethernet connectivity across machines, panels, and controllers in industrial environments without adding managed features.
