The NGI-U08 adds Gigabit Ethernet capacity to your industrial and commercial applications, such as factories, construction sites, supply rooms and warehouses. You can share large bandwidth-intensive files, such as CAD drawings and videos, improving efficiency and cutting costly downtime. The industrial-grade switch with its rugged high-strength case withstands vibration, shock and free fall. It can also operate in extreme temperatures ranging from -40 degrees to 167 degrees Fahrenheit.Because it is an unmanaged switch, the NGI-U08 does not require configuration before use. LEDs indicate when the switch is powered on and which Ethernet ports are showing activity. The NGI-U08 supports MAC address auto-learning and auto-aging for efficient routing, as well as automatic MDI/MDI-X crossover detection for plug-and-play functionality. IEEE 802.3x flow control allows smooth transmission of large files. DIP switch supports an alarm relay output function in which you can connect an alarm light or buzzer.The switch may be DIN mounted using the pre-installed rail clip, which mounts firmly to any standard 35 mm DIN rail. A 6-pin 9 - 57VDC terminal block supplies both primary and secondary power input. Device power must be supplied by LPS (Limited Power Source) circuit.
