With no setup required, Advantech B+B SmartWorx Unmanaged Industrial Ethernet Switches are cost-effective, best-in-class, UL Certified plug-andplay devices. These switches are designed for use in demanding industrial environments, offering unmatched performance, reliability, and value. Robust IP30 rated metal enclosure is designed to meet challenging industrial applications to provide efficient heat dissipation.

Models are available in standard 10/100Mbps speed for twisted pair ports and 100Mbps for fiber optic connections (on some models) while supporting full data transmission. The SE205 and SE205-T series switches offer store and forward technology, as well as MDI/MDIX auto sensing to ensure connectivity on the copper ports. Status LEDs indicate active link, speed and collision status.

Power is a 12-48 VDC redundant input design and is secured with a double protection mechanism: Polarity Reverse and Overload Protection. Polarity Reverse prevents damage to the switch in the event of incorrect power wiring. Overload Protection is a resettable fuse that prevents power overloads causing damage to the switch - once normal power is resumed the switch will restart automatically. Power-fail LEDs will activate to notify administrators of a failed condition as well as a power fault relay, to provide easy troubleshooting.
