Product Features8 x 10/100/1000 RJ45 ports and 2 x FX/GbE SFP uplink ports (for long-distance connection and cascade to control center)Optimizes network performance and ensures sufficient bandwidth by utilizing flow control and QoSSupports QoS function with 802.1p tag, allowing prioritization of critical control data such as EIP (EtherNet/IP), PROFINET, and GOOSE in industrial applications, minimizing latencyPrioritized transmission to devices and peripherals connected to port #1 and port #2Compliant 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-9428-RW is an unmanaged industrial-grade switch with 8-port 10/100/1000 RJ45 downlinks and 2-port FX/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, enabling fast and reliable long-distance connections to other switches or control centers.To maintain stable transmission of video and data, this device uses rate limiting and QoS (Quality of Service), prioritizing industrial applications utilizing protocols such as EIP, PROFINET, and GOOSE. Data priority and speed settings can be changed by operating DIP switches.This switch is built with industrial-grade components and housed in a high thermal conductivity IP30 aluminum case, protecting the device from tools and hazards. For reliability, redundant power and terminal block alarm relay contacts ensure non-stop operation and alert in case of power failure. Designed to withstand vibration, shock, free fall, and temperatures from -40°C to 75°C (-40°F to 167°F), it is suitable for locations such as tunnels.FunctionsRobust electrical and electromagnetic protection: Designed to withstand EMI (electromagnetic interference), ESD (electrostatic discharge), power surges, overvoltage, overcurrent, and reverse connection.Redundant power system: Designed to connect two power supplies and alarms simultaneously via a standard industrial terminal block. If one power supply fails, the switch starts supply from the alternative and triggers an alarm to notify technicians.Eco-friendly Green Ethernet technology: Supports 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: 8 x 10/100/1000BASE-T (RJ45), 2 x 100FX/GbE SFP Slots; DIP Switch (Power voltage drop alarm setting (PWR & RPS), Broadcast storm control setting (STORM), Port-based QoS setting (QoS on P1 & P2), Fiber port speed setting (100FX on P9 & P10)); LED Panel (PWR, RPS, ALM, SFP, 1000, LNK/ACT)Power: Input Voltage: 12V~60VDC; Power Consumption: System: 13W; Connection: Terminal Block; 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: 930 g (2.0 lb); Dimension (WxHxD): 50 x 164.9 x 122.2 mm (1.97 x 6.49 x 4.81 in)Ordering InformationModelDescriptionIEN-9428-RWUnmanaged 8 x 10/100/1000 RJ45 & 2 x FX/GbE SFP Industrial Switch, Railway ApprovalKey Features / Technical Specifications:8 x 10/100/1000 RJ45 ports2 x FX/GbE SFP uplink portsCompliant with EN 50155, EN 50121-4, EN 61373Operating temperature: -40°C to 75°CIP30 aluminum housingRedundant power systemDIN-Rail and rack-mount supportPower input: 12V~60VDCPower consumption: 13WWeight: 930gDimensions: 50 x 164.9 x 122.2 mm
