INS-8405E is an unmanaged 5-port, 10/100/1000 RJ45 downlink industrial switch with Premium features for very elementary communication between controllers and devices in automation settings, but important traffic requirements. It offers auto-negotiation on all its ports to aggregate devices easily in industrial ethernet applications. The switch offers various in-built traffic optimization and network performance features to prioritize important industrial data packets, prevent the loss of data during communication, and stable transmission. This switch is built with industrial-grade components, enclosed in an IP30 metal case to protect the device from tools and hazards. Designed to withstand vibration, shock, free fall, interference, and temperatures ranging from -40°C~75°C (-40°F~167°F) it suits extreme industrial environments.


Ruggedized Components Designed for Harsh Industrial Environments
Built with industrial-grade components, good thermal conductivity, and enclosed in an IP30 metal case, this Ethernet switch is resistant to extreme environments, vibration, EMI (electromagnetic interference), ESD (electrostatic discharge), power surge, over-voltage, over-current, and reverse polarity. It withstands operation at extreme temperatures between -40°C~75°C (-40°F~167°F). It follows international safety standards like CE, FCC, and ROHS for safe operation.


Quick and Convenient Installation with Auto-negotiation
INS-8405E works as soon as it is connected and makes installation convenient. One 12~48VDC power supply connects to the 3-pin terminal block for power. The 10/100/1000 Mbps ports use MDI/MDI-X connection for auto-negotiation to work as soon as connected to other network devices at the required speed without extra software installation needed. The LED light displays when the device is in operation. The slim and small design allows it to fit at different locations for many devices to operate in the same network and can be mounted to a standard TH35 DIN rail.


Traffic Control Mechanisms to Optimize Bandwidth Usage
Traffic control mechanisms regulate excessive traffic to avoid delay, data loss and connection issues between devices. INS-8405E offers mechanisms such as Flow and Storm Control that prevent devices from overwhelming each other during the exchange of data and to keep the flux at a tolerable rate, hence keeping devices working within their capacity and avoiding the network from collapsing.


Intelligent VLAN Data Forwarding
INS-8405E is aware enough to read the source and destination of VLAN tagged data packets. This unmanaged switch delivers VLAN packets without changing or dropping them assuring operational data in industrial fields is delivered safely across devices.


Critical Data Transmission Priority
INS-8405E streamlines the execution of time-sensitive applications with the 802.1p Tag QoS by classifying data into high and low priority. Mission-critical applications in industrial automation like manufacturing and monitoring can be done without delay through port priority on ports #1 and #2 even during high traffic.


Prioritizes Industrial Standard Protocols
Industrial automation applications employ packet protocols that focus on delivering data under tight time constrains. This unmanaged switch is configured with iQoS to prioritize industrial application protocols and deliver time-sensitive data used in industrial applications first, including Ethernet/IP, PROFINET, and GOOSE (Generic Object Oriented Substation Events).


Connects Large Network Groups and Facilitates Data for Monitoring Systems
During network discovery unmanaged switches can cause device flapping and make it difficult for monitoring systems to access device data. INS-8405E avoids device flapping when connected to a managed switch. Using the LLDP Filter feature the device can be used in large networks. It allows other devices in the network to exchange identifiable data for accurate monitoring without concerns from detecting erroneous messages and false alerts in the presence of an unmanaged switch.
