Product Features5 x 10/100/1000 RJ45 downlink and 2 x GbE SFP uplink ports (for long-distance connection and cascading to control centers)Optimizes network performance and ensures sufficient bandwidth by utilizing flow control and QoSSupports QoS functionality via 802.1p tags, allowing prioritization of critical control data such as EIP (EtherNet/IP), PROFINET, and GOOSE for industrial applications, minimizing latencyPriority transmission to devices and peripherals connected to port #1Compliant with EN 50155, EN 50121-4, and EN 61373 standards, making it ideal for safe and reliable railway applicationsOperating temperature range: -40°C to 75°C (-40°F to 167°F), IP30 aluminum housingProduct OverviewThe IEN-9425-RW is an unmanaged industrial-grade switch with 5-port 10/100/1000 RJ45 downlinks and 2-port GbE SFP uplinks, designed to meet the thermal and environmental requirements of railway applications. Downlink ports connect to industrial devices and controllers, while fiber ports provide noise-free gigabit Ethernet transmission for fast and reliable long-distance connections to other switches or control centers.To maintain stable data transmission, this device uses rate limiting and QoS (Quality of Service), prioritizing industrial applications utilizing protocols such as EIP, PROFINET, and GOOSE.This switch is built with industrial-grade components and housed in a high thermal conductivity IP30 aluminum case to protect the device from tools and hazards. Certified for railway applications, it implements standard and safe communication, withstanding vibration, shock, free fall, and temperatures from -40°C to 75°C (-40°F to 167°F).FunctionsRobust electrical and electromagnetic protectionDesigned to withstand EMI (Electromagnetic Interference), ESD (Electrostatic Discharge), power surges, overvoltage, overcurrent, and reverse connection.Advanced QoS supportQoS (Quality of Service) for efficient data transmission to mission-critical applications and storm control for traffic limitation at defined rates.Eco-friendly Green Ethernet technologyGreen Ethernet technology compliant with IEEE 802.3az Energy Efficient Ethernet (EEE), automatically adjusting power consumption.SpecificationsStandards: IEEE 802.3 (10BASE-T), IEEE 802.3u (100BASE-TX), IEEE 802.3ab (1000BASE-T), IEEE 802.3z (1000BASE-SX/LX), IEEE 802.3 (Nway Auto-negotiation), IEEE 802.3x (Flow Control), IEEE 802.1p (Class of Service)Interface: 5 x 10/100/1000BASE-T (RJ45), 2 x GbE SFP Slots, DIP Switch (Power voltage drop alarm setting for PWR & RPS), LED Panel (PWR, SFP, 1000, LNK/ACT)Power: Input Voltage: 20V~60VDC; Connection: Terminal Block, Mini-DIN; Power Consumption: System: 13W; Alarm Relay: One relay output with current carrying capacity of 1 A @ 24V DCMechanical and Environment: Housing: Aluminum Case (IP30 protection); Mounting Kit: DIN-Rail, Rack-mount; Operating Temperature: -40°C~75°C (-40°F~167°F); Storage Temperature: -40°C~85°C (-40°F~185°F); Operating/Storage Humidity: 5 to 95% RH (non-condensing); Weight: 869 g (1.9 lb); Dimension (WxHxD): 50 x 164.9 x 122.2 mm (1.97 x 6.49 x 4.81 in)Ordering Information:ModelDescriptionIEN-9425-RWUnmanaged 5 x 10/100/1000 RJ45 & 2 x GbE SFP Industrial Switch, Railway ApprovalTechnical Specifications / Features:5 x 10/100/1000 RJ45 downlink ports2 x GbE SFP uplink portsUnmanaged industrial switchRailway certified (EN 50155, EN 50121-4, EN 61373)Operating temperature: -40°C to 75°CIP30 aluminum housingPower input: 20V~60VDCDIN-Rail and rack-mount supportQoS and flow control supportEMI, ESD, surge, overvoltage, overcurrent, and reverse connection protectionIEEE 802.3az Energy Efficient EthernetDimensions: 50 x 164.9 x 122.2 mmWeight: 869 g
