Description

NS-208PSE/NSM-208PSE - 8-port Industrial 10/100 Mbps Ethernet with 8-PoE (PSE) Switch
NS-208PSE-4/NSM-208PSE-4 - 8-port Industrial 10/100 Mbps Ethernet with 4-PoE (PSE) Switch

The NS-208PSE/NS-208PSE-4 is an 8-port unmanaged PoE (Power over Ethernet) Industrial Ethernet switch, it supports 8/4 PoE ports which are classified as power source equipments (PSE). The NS-208PSE/NS-208PSE-4 makes centralized power supply come true and provides up to 15.4 W of power per port. The NS-208PSE/NS-208PSE-4 can be used to power IEEE802.3af compliant powered devices (PD) by Ethernet cable and eliminates the need for additional power wiring.
The NS-208PSE/NSM-208PSE is exactly the same as the NS-208PSE-4/NSM-208PSE-4, except for the PoE ports.

● Each port supports both 10/100 Mbps speed auto negotiation
● Full duplex IEEE 802.3x and half duplex backpressure flow control
● 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
● Automatic MDI/MDI-X crossover for plug-and-play
● Store-and-forward architecture
● 8 PoE ports for NS-208PSE/NSM-208PSE;
● 4 PoE ports for NS-208PSE-4/NSM-208PSE-4
● Supports +46 ~ +55 VDC power input
● DIN-Rail Mounting
