NS-208R CR
Conformal Coated 8-port Industrial 10/100 Mbps Ethernet Switch
NS-208R Ethernet switch is designed for industrial applications, such as rolling stock, vehicle, and railway applications. The NS-208R is an unmanaged Ethernet switch with 8x10/100Base-T(X) ports which is compliant with EN50155 request.
NS-208R provides a wide 12 to 48 VDC power range to fit all the common power standards found in industrial automation, without external power converters. The wide power input lowers installation and maintenance costs.
The flow control mechanism is also negotiated. There is link/data rate LEDs for each port to aid troubleshooting. Port connectors are shielded RJ-45.
- EN50155-certified for harsh railway standards
- Cost-effective
- Automatic MDI/MDI-X crossover for plug-and-play
- Store-and-forward architecture
- Full duplex IEEE 802.3x and half duplex backpressure flow control
- Each port supports both 10/100 Mbps speed auto negotiation
- Supports +12 ~ +48 VDC power input
- Supports operating
