20 ports network switch IES3020 Series

unmanagedgigabit Ethernetlayer 2

20-port 100M/Gigabit Layer 2 Unmanaged Industrial Ethernet Switch -Support 4 Gigabit fiber ports (SFP slot), 16 100M fiber and copper ports optional -Gigabit bandwidth can enable high performance and speed transmission of large amounts of video, voice, and data -Support dual power supply input, input voltage: 12~48VDC -Support -40~75℃ wide operating temperature range Power supply input is two independent power supply circuits, which can ensure the device normal operation when one of the power supplies breaks down. DIP switch can achieve power supply alarm, flow control and storm suppression. When power supply link failure occurs, ALARM indicator will be bright and send out alarm, meanwhile, alarm device connected to the relay will send out alarm for rapid scene troubleshooting. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in smart grid, rail transit, smart city, safety city, new energy, intelligent manufacturing and other industrial fields.
