The LNP-0800G-24 is an industrial gigabit unmanaged PoE+ Ethernet switch with P.S.E. function and a relay output of 24VDC at 1A. The LNP-0800G-24 supports Power over Ethernet, a system that transmits electrical power along with data to remote devices over standard twisted-pair cable in an Ethernet network. The LNP-0800G-24 supports wide-range 9~55VDC power inputs and generates up to 30W P.S.E. power output per port. The LNP-0800G-24 switch has 8 X 10/100/1000Base-T(X) P.S.E. (Power Sourcing Equipment) ports. P.S.E. is a device (switch or hub for instance) that will provide power in a PoE setup. The LNP-0800G-24 switch is one of the most reliable choices for PoE Ethernet applications.
