RS485 control signal, lightning protector, 4-20MA analog signal,
lightning protector 5V/12V/24V.
Brief introduction
The control signal lightning arrester is a lightning protection
measure developed by Zhejiang tohr Electric Co., Ltd., which is
independently developed for signal circuit protection. The
lightning protection for the control signal and the twisted pair
data line can prevent the induced overvoltage current from the
thunder or the industrial noise and the other instantaneous surge
voltage to cause damage or instantaneous interruption of all kinds
of dial-up equipment or systems.
Product features
1. energy saving, environmental protection, easy installation,
suitable for all kinds of standard interface types.
2. the coefficient of standing wave is small and the range of
working frequency is wide
3. when lightning strikes, there will be no need to stop the
electrical equipment when it enters the electric surge, and it will
not affect the operation of the normal equipment.

Working principle of product
The control signal surge protector is connected to the front end of
the protected equipment. When the transmission line is impacted by
the inductive thunder and other transient overvoltage, the impact
current is discharged to the earth through the protection branch of
the surge protector, and the output voltage is placed in the
allowable voltage range of the equipment, thus ensuring the safety
of the operating equipment.
Use of attention
1. lightning arrester should be connected to the shortest possible
line. The protector grounding adopts terminal grounding mode, and
the grounding wire must be connected to the lightning protection
ground wire (or the enclosure of the protected equipment). The
shielding wire of signal can be directly connected to the grounding
terminal.
2. please recognize the interface and the way of connection
3. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed inductors on the ability of
lightning electromagnetic pulse.
