IGS-600-4PH(E)24, 6-port copper unmanaged full-gigabit Ethernet switches, support 4-port Power-over-Ethernet on ports 1 to 4. 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. IGS-600-4PH(E)24 support IEEE 802.3/802.3u/802.3x/803.3ab with 10/100/1000M, full/half-duplex, MDI/MDI-X auto-sensing to provide an economical high-bandwidth solution for your industrial Ethernet network.
