IGS-401F-4PH24-SC001, 4-port unmanaged Gigabit Ethernet switches, support 4-port Power-over-Ethernet on ports 1 to 4 and one 1000Base-X optical transceiver for multi-mode fibers and 550M. The switches are classified as power source equipment (PSE) can be used to power IEEE 802.3af/at standard devices (PD), eliminating the need of additional power cable wiring. Moreover, it built-in power input booster of 24 VDC and 48VDC for PoE/PoE output without external power converters or power supplies, it is able to fit all the common 24/48 VDC power system found in industrial fields or cabinets. These PoE switches support IEEE 802.3/802.3u/802.3x/802.3ab with 10/100/1000M, full/half-duplex, MDI/MDI-X auto-sensing to provide an economical highbandwidth solution for your industrial Ethernet network.
