Unmanaged Switches

Unmanaged Industrial Switch



INS-840G, 16-port 10/100/1000Base-T is a current development of Volktek’s Unmanaged Industrial Gigabit Ethernet Switch, specifically engineered with an excellent tolerance capability to withstand the harsh industrial environments like vibration, shock and extreme temperature range between -40°C~70°C. The switch is designed with a rugged IP30 aluminum housing featuring various EMC protections such as Surge and ESD. This is for delivering a secure and uninterruptable operation in mission-critical applications like factory automation. 

Robust Performance
INS-840G is equipped with industrial grade components, enclosed with a rugged IP30 hardened aluminum housing to sustain in harsh industrial temperatures ranging between -40°C ~ 75°C.

Industrial Grade EMC Protection Design
INS-840G is designed with efficient EMC protection to secure the device against electromagnetic failures. 

Strong Protection Against Electrical Threats
INS-840G provides Reverse Polarity Protection to prevent internal circuitry damage caused by wrong combinations of positive and negative poles.

Redundant Power Supply
INS-840G development uses a standard of industrial terminal block along with wide-range redundant power inputs extending from 12 up to 60VDC. 

Auto Negotiable Link Speed Control
INS-840G provides an auto negotiation feature to balance the data transmission speed between the switch and the connected PLCs.

Advanced QoS Support
INS-840G is developed with comprehensive IEEE 802.1p QoS mechanisms that support tag based priority queuing mechanism. 

Eco-friendly Green Ethernet Design
INS-840G implements IEEE 802.3az Energy Efficient Ethernet (EEE) compliant Green Ethernet technology.
