The Empire State Building is hit nearly 100 times a year. Fact: Lightning often strikes the same place repeatedly, especially if it’s a tall, pointy, isolated object. Myth: Lightning never strikes the same place twice. Here are a few myths and facts about lightning, courtesy of the National Oceanic and Atmospheric Administration: Like trees and other tall objects, transmission poles are likely to intercept lightning strikes, but they do not attract lightning. New transmission lines are built with a grounded shield wire along the top of the poles, above the conductors, to protect the line from lightning. check to make sure the power supply voltage and polarity are correctĪ.Hot and humid summer days can often produce violent thunderstorms. check to make sure the RS-485 interface is correctly connectedĬ. check to make sure the RS-422 interface is correctly connectedī. The user shall try to avoid hanging by credible grounding to ensure the safety of communication during operation.Ī. ATC-109N Photoelectric Isolation Data Repeater terminal Pin FGND is designed for surge grounding protection. The rapid Transient Voltage Suppressor (TVS) can effectively inhibit lightning and ESD. ATC-109N Photoelectric Isolation Data Repeater can provide 1000W lightning strike and surge protection power on each line. The transient high voltage induced in interface data line tries to release energy to the ground wire via the minimum resistance route of the device and thus can easily cause damage to interface parts. The connection pins are Terminal: V+,V-Ĭommon repeater has no large energy protector. The power supply voltage is +7.5V-+24V, current 100mA. The Terminal pin shall be connected with RS-422 or RS-485 network equipments according to definition instruction.ĪTC-109N Photoelectric Isolation Data Repeater supports following 3 relay communication modes:ĪTC-109N Photoelectric Isolation Data Repeater can adopt the product’s DC9V power adapter for power supply or adopt power from other DC power or device. Connect the product’s power converter with +9V socket. Please read the User’s Manual carefully before installing ATC-109N Photoelectric Isolation Data Repeater.
