Product Features5 x 10/100/1000 RJ45 ports (system supporting multiple Ethernet speed applications)Auto-negotiation ports enable operation without installing additional devicesUtilizes flow control and storm control to ensure network stability and prevent data overflowVLAN pass-through improves data transmission efficiencySystem resistant to interference in environments with multiple machinesOperating temperature range: -40°C to 75°C (-40°F to 167°F), IP30 metal housingProduct OverviewThe INS-8405A is an unmanaged 5-port 10/100/1000 RJ45 downlink industrial switch with auto-negotiation, providing very basic communication between controllers and devices in automation environments. This switch offers auto-negotiation on all ports for easy device aggregation in industrial Ethernet applications. It also features various built-in traffic optimization functions, including storm control and flow control, and supports VLAN to improve data transmission and enhance communication security between devices. Built with industrial-grade components and housed in an IP30 metal case, it protects devices from tools and hazards. Designed to withstand vibration, shock, free fall, and interference, it operates in a temperature range of -40°C to 75°C (-40°F to 167°F), making it suitable for harsh industrial environments.FunctionsRugged components designed for harsh industrial environmentsConstructed with industrial-grade components and excellent thermal conductivity, this Ethernet switch is housed in an IP30 metal case and is resistant to extreme environments, vibration, EMI (electromagnetic interference), ESD (electrostatic discharge), power surges, overvoltage, overcurrent, and reverse connection. It operates in extreme temperatures from -40°C to 75°C (-40°F to 167°F) and complies with international safety standards such as CE, FCC, and ROHS for safe operation.Quick and convenient installation with auto-negotiationThe INS-8405A operates simply by connecting it, making installation convenient. Connect a 12~48VDC power supply to the 3-pin terminal block. The 10/100/1000 Mbps ports use MDI/MDI-X connections and work immediately when connected to other network devices at the required speed. No additional software installation is required. LED lights indicate device operation. Its slim and compact design allows placement in various locations, enabling many devices to operate on the same network, and it can be mounted on a standard TH35 DIN rail.Traffic control mechanisms to optimize bandwidth usageTraffic control mechanisms adjust excessive traffic to avoid delays, data loss, and connection issues between devices. The INS-8405A provides mechanisms such as flow control and storm control to ensure devices do not overwhelm each other during data exchange and maintain flow at acceptable speeds. This allows devices to operate within their capabilities and prevents network collapse.Intelligent VLAN data transferThe INS-8405A can read the source and destination of VLAN-tagged data packets. This unmanaged switch reliably delivers operational data between devices in industrial fields without modifying or deleting VLAN packets.SpecificationsStandards: IEEE 802.3 (10BASE-T), IEEE 802.3u (100BASE-TX), IEEE 802.3ab (1000BASE-T), 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), LED Panel: PWR, 1000, LNK/ACTPower: Input Voltage: 12~48VDC, Connection: Terminal Block, Power Input Polarity Protection: Present, Current Overload Protection: Present, Power Consumption: 3WMechanical and Environment: Housing: Aluminum (IP30 Protection), Mounting: DIN-Rail, Wall 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: 160 g (0.3 lb), Dimension (WxHxD): 23.6 x 111.5 x 73.8 mm (0.93 x 4.39 x 2.90 in)ModelDescriptionINS-8405AUnmanaged 5 x 10/100/1000 RJ45 Industrial Switch*Specifications subject to change without prior notice.Key Features / Technical Specifications:5 x 10/100/1000 RJ45 portsAuto-negotiation on all portsFlow control and storm controlVLAN pass-throughOperating temperature: -40°C to 75°CIP30 metal housingPower input: 12~48VDCDIN-rail and wall mountableDimensions: 23.6 x 111.5 x 73.8 mmWeight: 160 g
