INS-840G is an unmanaged industrial Gigabit Ethernet switch with sixteen 10/100/1000Base-T ports. It is built with industrial-grade components, enclosed in IP30 aluminum casing, and designed to withstand vibration, shock, free fall, and temperatures ranging from -40°C to 75°C.

Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.
Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.
Auto Negotiable Link Speed Control
Auto negotiation of transmission speed between the switch and the connected PLC (Programmable Logic Controller).
Advanced QoS Support
QoS (Quality of Service) for efficient data transmission to mission-critical applications.
Eco-friendly Green Ethernet Technology
IEEE802.3az Energy Efficient Ethernet (EEE) compliant with Green Ethernet technology for automatic adjustment of power consumption.
