Lightning guard unit for RS-485 

Lightning guard unit for RS-485 is designed for protection from surge overvoltage (which appears as a result of thunderstorms) in the industrial interconnections via RS-485. Lightning guard unit is a box which has integrated printed circuit board with elements. The main protection elements are zinc-oxide varistors and gas discharges. If overvoltage occurs variable resistor limits the voltage and further increase in input voltage triggers lightning protector, which abridges communication with the ground for a short time period, thereby preventing the penetration of impulses to the protected device. Lightning protection unit is installed between the communication line and equipment. 
Lightning protection unit must be connected to the ground bus.

 Device functions: 

• Lightning overvoltage Protection
