KNA4 is an intrinsically safe Gigabit Ethernet conversion module for industrial mines, supporting two 10/100/1000M RJ45 Ethernet ports and two 1000M optical ports (SC/ST/FC interface K is optional), and supports IEEE802 .3. IEEE802.3x, IEEE802.3u IEEE802.3z, IEEE802.3u, IEEE802.3ab standards, support, full-duplex/half-duplex, MDI/MDI-X self-adaptive. Supporting STP, RSTP, RING ring network is suitable for various project requirements, and the LED light system status indication can help system maintainers monitor the connection status of the network. The product is designed according to the requirements of intrinsic safety, with wide voltage drop power input and low power consumption design, which can adapt to the harsh industrial and mining working environment.
