INS-8405A is an unmanaged 5-port, 10/100/1000 RJ45 downlink industrial switch for very elementary communication between controllers and devices in automation settings. 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 with Storm and Flow Control and is VLAN aware to improve the transmission of data and increase safety in the communication of devices. 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-8405A 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-8405A 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-8405A 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.
