Switch công nghiệp 8 cổng PoE Ethernet ICP DAS NSM-208PSE-R


The NSM-208PSE is an 8-port unmanaged PoE (Power over Ethernet) Industrial Ethernet switch. It supports 8 PoE ports which are classified as power source equipments (PSE). The NSM-208PSE make centralized power supply come true and provide up to 15.4 watts of power per port. The NS-208PSE/NSM- 208PSE can be used to power IEEE802.3af compliant powered devices (PD) by Ethernet cable and eliminates the need for additional power wiring.

  • Automatic MDI/MDI-X crossover for plug-and-play

  • Each port supports both 10/100Mbps speed auto negotiation

  • Store-and-forward architecture

  • Full duplex IEEE 802.3x and half duplex backpressure flow control

  • 8 PoE ports with Power Sourcing Equipment (PSE) operation

  • Auto-detection of PD (powered devices) and automatic power management

  • Over-temperature, over-current and over/under-voltage detection

  • Supports operating temperatures from -40°C ~ +75°C

  • DIN-Rail mount

  • NSM-208PSE-R meets railway standards. "-R" stands for products with MIL SPEC conformal coating protection
