NSM-208PSE-24V Unmanaged 8-Port PoE (PSE) Ethernet Switch, +24 VDC Input

Centralised PoE power for an unmanaged industrial Ethernet segment. The NS-205PSE-24V CR switches traffic between five 10/100Base-TX ports, and four of those ports act as power sourcing equipment (PSE) to feed IEEE 802.3af/at powered devices. Each PSE port supplies up to 15.4 W, so a single DC supply within the +12 VDC to +32 VDC range can power remote endpoints without a separate local supply at each device.The switch suits sites where a +48 VDC PoE supply is not available. Store-and-forward processing, a 2K MAC table, a 1 Mbit frame buffer and IEEE 802.3x and back pressure flow control support reliable forwarding. Reverse polarity protection and an operating range of -40 °C to +75 °C add robustness for cabinet installations.Status LEDs show power, link and activity, 10/100M speed and PD detection, which simplifies commissioning and fault finding. The plastic casing mounts on a DIN-rail and measures 31 x 157 x 113 mm (W x L x H). The unit carries CE, UKCA, FCC, RoHS and WEEE marks.ApplicationsPowering PoE devices at remote points in industrial Ethernet networks from a 24 VDC supplyCentralised PoE power distribution where a +48 VDC PoE supply is not available

NSM-205PSE-24V CR is an unmanaged industrial Ethernet switch with five 10/100Base-TX RJ-45 ports, four of which act as PoE PSE (power sourcing equipment) ports that supply power to connected powered devices over the data cable. Each PoE port delivers up to 15.4 W, so a single 24 VDC supply can power several remote devices from one central point.The switch is intended for installations where a +48 VDC supply is not available. Its built-in boost stage allows the PoE ports to be fed from the wide +12 VDC to +32 VDC input range, which keeps the power architecture simple in cabinets and on DIN rails.The metal casing, IP30 rating and operating range of -40 °C to +75 °C suit demanding industrial locations. Store-and-forward switching, IEEE 802.3x flow control and 1500 Vrms isolation complete the specification for reliable plant-floor networking.ApplicationsPowering PoE devices from a central 24 VDC supplyIndustrial Ethernet networks where a +48 VDC supply is not available

NSM-208PSE-4 CR is an unmanaged industrial Ethernet switch with eight RJ-45 ports, four of which act as PoE power sourcing equipment (PSE). Each PoE port can deliver up to 15.4 W, so IEEE 802.3af compliant powered devices such as IP cameras, access points or sensors can be fed over the same cable that carries their data, removing the need for separate power wiring to the field.Each port auto-negotiates between 10 and 100 Mbps and uses store-and-forward switching. The unit detects powered devices automatically and manages PoE power per port. It also monitors for over-temperature, over-current and over/under-voltage conditions. The metal casing is designed for DIN-rail mounting in control cabinets.The switch operates from -40 °C to +75 °C and stores from -40 °C to +85 °C, with 10% to 90% RH non-condensing humidity. It carries CE, UKCA, FCC, RoHS and WEEE markings.ApplicationsPowering IEEE 802.3af compliant powered devices over EthernetCentralised PoE distribution to networked field devicesIndustrial Ethernet networks in DIN-rail mounted control cabinets

The NSM-208PSE-M12 is an unmanaged Ethernet switch for industrial networks where connectors must stay secure under vibration and shock. Each of its eight M12 ports acts as a Power Sourcing Equipment (PSE) port, supplying IEEE 802.3af compliant PoE of up to 15.4 W per port, so powered devices can be connected without a separate supply at each node.The switch is built to the railway standard EN50155, with EN50121-3-2 and EN50121-4 compliance, and also meets NEMA TS2. It accepts a +46 VDC to +53 VDC input with reverse polarity protection and offers 1500 Vrms isolation for one minute. Its metal casing is wall mounted and rated for operation from -40 °C to +75 °C.This listing includes eight M12D-4P-IP68 connectors and eight A-CAP-M12M caps, one M12A-5P-IP68 connector and one A-CAP-M12F cap, and the 4SIX1K0000003 wall mount kit.ApplicationsIndustrial Ethernet networks in harsh environmentsInstallations subject to high vibration and shockRailway applications requiring EN50155 compliancePowering IEEE 802.3af compliant PoE devices from a single switch
