Industrial RS485 signal protector, control signal, surge protector,
arrester 5V12V24V.
Product Details
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 control
signal lightning arrester is mainly used for lightning
(overvoltage) protection along the low voltage control signal
circuit, which is widely used in the financial system,
telecommunication system, transportation system, petrochemical
industrial control system, such as various data transmission lines,
monitoring and control lines, instrument signal lines and so on.

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.
Product features
1. core components are strictly screened and their performance is
superior.
2. Design of low capacitance and inductance and superior
transmission performance
3. it has self recovery function and provides multiple protection
under lightning prone environment.
Use of attention
1. identify the input / output interface identifier of the
lightning protector, input the external line and output the device.
2. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed inductors on the ability of
lightning electromagnetic pulse.
3. the grounding of industrial control signal lightning arrester
should be connected to the grounding grid through electronic
switches.
