NSM-108 Unmanaged 8-Port Industrial Ethernet Switch, 10/100Base-TX

The NS-208 CR is an unmanaged industrial Ethernet switch providing eight shielded RJ-45 ports for 10/100Base-TX networks. Each port negotiates its speed automatically and detects crossover wiring itself, so devices can be connected without special cables or manual configuration.Frames are buffered and forwarded using store-and-forward processing, and the switch supports both IEEE 802.3x full-duplex flow control and back-pressure flow control in half-duplex mode. A per-port link and activity LED, plus power and speed indicators, help with commissioning and fault finding.Designed for DIN-rail mounting, the switch accepts a +12 to +48 VDC supply with reverse polarity protection and operates from -40 to +75 °C. It suits engineers who need a simple, dependable Ethernet backbone inside control cabinets without the setup overhead of a managed switch.ApplicationsIndustrial Ethernet networking in DIN-rail control cabinetsConnecting 10/100Base-TX devices in automation and machine control systems

The NSM-205GP is an unmanaged Gigabit Ethernet switch that combines four PoE+ ports with a fibre-ready uplink, so one industrial power supply can feed both data and power to nearby devices. Ports 1 to 4 act as power sourcing equipment (PSE) and deliver up to 30 W per channel to IEEE 802.3af/at powered devices.Voltage boost technology is designed to keep a full PSE voltage available on every PoE port when the switch runs from a 24 V industrial source, which helps when standard devices are placed at the far end of a cabinet or machine. Dual redundant +18 ~ +55 VDC inputs with reverse polarity protection and a relay alarm output add resilience to the power side of the installation.Suited to centralised PoE distribution in compact control panels and machine enclosuresStore-and-forward switching with an 8 K MAC table and jumbo frame support up to 10 K at 1000MApplicationsCentralised PoE power distribution to IEEE 802.3af/at powered devicesIndustrial Ethernet network segments in control panels and machine enclosuresInstallations supplied from 24 V or 48 V industrial DC power

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

The NSM-206PSE is an unmanaged 6-port Ethernet switch that acts as a Power Sourcing Equipment (PSE) on ports 1 to 4. It lets you centralise power for connected devices, so powered endpoints can be fed over the same cable as their data link, with up to 30 W per channel.Ports 1 to 4 are fully compliant with IEEE 802.3af and 802.3at, with automatic detection and power management. The unit runs from a redundant dual 12 to 57 VDC input with reverse polarity protection, and the store and forward switching architecture operates at wire speed with 10/100 Mbps auto negotiation on every port.The metal-cased switch mounts on a DIN rail or, optionally, on a wall, and is rated for an operating temperature of -40 °C to +75 °C. The ordering code CR variant is supplied with a metal case and is RoHS compliant.ApplicationsCentralised power distribution to IEEE 802.3af/at powered devices (PD)Industrial Ethernet networks requiring PoE from a DIN-rail mounted switch
