NS-208R - Robust 8-port Industrial Unmanaged Ethernet Switch

8-Port Industrial 10/100 Mbps Unmanaged Ethernet Switch, DIN-Rail mount (Robust Version). Supports operating temperatures from -40°C ~ +75°C (-40°F ~ 167°F).

  Price:  $249.00  

Features

The NS-208R has 8 Ethernet Switching ports that support 10/100Base-T(X), with a 10/100M auto-negotiation feature and auto MDI/MDI-X function. It can connect 8 workstations and automatically switches the transmission speed (10 Mbps or 100 Mbps) for corresponding connections.

The flow control mechanism is also negotiated. NS-208R is designed especially for mission critical and harsh environmental applications since it comes ready with conformal coating.

  • Automatic MDI/MDI-X crossover for plug-and-play
  • Full duplex IEEE 802.3x and half duplex backpressure flow control
  • Store-and-forward
  • Supports 4 kV Ethernet ESD protection
  • Provides ESD protection 4 kV, EFT protection 3 kV and Surge protection 2 kV for power line
  • 2 Gbps high performance memory bandwidth.
  • Supports +12 ~ 48V DC voltage
  • Supports operating temperatures from -40°C ~ +75°C
  • DIN-Rail Mount
