Product information "NS-208PSE-4 Unmanaged PoE Industrial Ethernet Switch, 8-port with 4 PSE Ports"
The NS-208PSE-4 is an unmanaged industrial Ethernet switch with eight 10/100Base-TX RJ-45 ports, four of which act as Power Sourcing Equipment (PSE). It lets one cabinet supply both data and power to compatible endpoints, so separate power cabling to each device can be avoided.
Each PoE port delivers up to 15.4 W and detects connected powered devices automatically, managing power allocation as devices are connected or removed. The switch is 100% IEEE 802.3af compliant and monitors for over-temperature, over-current and over/under-voltage conditions to protect the installation.
Store-and-forward, wire-speed switching with a 1024-entry MAC table and 1500 Vrms isolation suits DIN-rail installations in plastic housings across a -40 ~ +75 °C operating range. The NS-208PSE-4 CR is the ordering code offered here.
Applications
- Centralised power supply to IEEE 802.3af powered devices over Ethernet cable
- Removing the need for additional power wiring to Ethernet-connected devices
- Industrial Ethernet networking in DIN-rail mounted control cabinets

NS-208PSE CR is an unmanaged 8-port 10/100 Mbps Ethernet switch that also sources power to the network. All eight RJ-45 ports operate as PSE (power sourcing equipment), each delivering up to 15.4 W, so IEEE 802.3af powered devices can receive power over the same Ethernet cable that carries their data, without separate power wiring.The switch detects powered devices automatically and manages power per port. It also monitors for over-temperature, over-current and over/under-voltage conditions. Store and forward processing with wire speed switching, IEEE 802.3x flow control and a 2048-entry MAC table support efficient forwarding on small industrial networks.The plastic-cased unit is designed for DIN-rail mounting and is rated for operation from -40 °C to +75 °C at 10% to 90% RH, non-condensing. It provides 1500 Vrms isolation for 1 minute and includes reverse polarity protection.ApplicationsCentralised power supply for IEEE 802.3af powered devices over EthernetIndustrial Ethernet networks where separate power wiring to devices is to be avoided
