8 ports 10/100M Unmanaged Industrial Ethernet Switch.

IT-ES308-IU-4F series are a smart plug-and-play industrial Ethernet switch, which can provide economical solution for your Ethernet. Its dustproof fully sealed structure (or protective case of IP30 level), over-current, over-voltage and EMC protected redundant double power input as well as built-in intelligent alarm design can help system main tenancy personnel monitor the network operation, which can work reliably in harsh and dangerous environment.

IT-ES308-IU-4F series supports 4 TP ports and 4 fiber ports. TP (RJ45) Support 10/100Base-T(X), Full/Half duplex mode, and auto MDI/MDI-X connection.100BaseFX ports supports single/multi mode, SC/ST connector, optional.
