Product Features8 x 10/100/1000 RJ45 ports and 2 x GbE SFP uplink ports (for long-distance connection to control centers and cascading)Optimizes network performance and ensures sufficient bandwidth by utilizing flow control and QoSSupports QoS function via 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 international standards IEEE 1613 and IEC 61850-3, providing reliability and safety for harsh power supply systemsOperating temperature range: -40°C to 75°C (-40°F to 167°F), IP30 aluminum housingProduct OverviewThe IEN-9428-SS is an unmanaged industrial-grade switch equipped with 8-port 10/100/1000 RJ45 downlinks and 2-port GbE SFP downlinks, designed to meet the requirements and environmental conditions of substation applications. The downlink ports connect to industrial equipment and controllers, while the fiber ports provide noise-free gigabit Ethernet transmission, enabling fast and reliable long-distance connections to other switches or control centers.To maintain stable video and data transmission, the device uses rate limiting and QoS (Quality of Service), prioritizing industrial applications using protocols such as EIP, PROFINET, and GOOSE. Users can change data priority and speed settings via DIP switches.This switch is built with industrial-grade components and enclosed in a high thermal conductivity IP30 aluminum case, protecting the device from tools and hazards. For reliability, redundant power and alarm relay contacts on the terminal block ensure uninterrupted operation and provide warnings in case of power loss. It is designed to withstand vibration, shock, free fall, and temperatures from -40°C to 75°C (-40°F to 167°F), making it suitable for harsh environments.FunctionsRobust electrical and electromagnetic protection: Designed to withstand EMI (electromagnetic interference), ESD (electrostatic discharge), power surges, overvoltage, overcurrent, and reverse polarity.Redundant power system: Can be powered simultaneously by two different power supplies, such as SDR-480P-48 power supply or IRA-120/IRA-160 DIN-rail mountable AC to DC adapters, with power failure alarm.Eco-friendly Green Ethernet technology: Compliant with IEEE 802.3az Energy Efficient Ethernet (EEE), equipped with Green Ethernet technology that automatically adjusts power consumption.SpecificationsStandards: IEEE 802.3, 10BASE-T, IEEE 802.3u, 100BASE-TX, IEEE 802.3ab, 1000BASE-T, IEEE 802.3z, 1000BASE-SX/LX, Nway Auto-negotiation, IEEE 802.3x Flow Control, IEEE 802.1p Class of ServiceInterface: 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, Connection: Terminal Block, 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 Humidity: 5 to 95% RH (non-condensing), 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-SSUnmanaged 8 x 10/100/1000 RJ45 & 2FX/GbE SFP Industrial Switch, Substation ApprovalKey Features / Technical Specifications8 x 10/100/1000 RJ45 ports2 x GbE SFP uplink portsQoS and flow control supportIEEE 1613 and IEC 61850-3 compliantOperating temperature: -40°C to 75°CIP30 aluminum housingRedundant power systemDIN-Rail and rack-mount supportPower input: 12V~60VDCDimensions: 50 x 164.9 x 122.2 mmWeight: 930 g
