Computer room monitoring signal, lightning protector, multi interface protection, BNC monitoring and signal protection
Product 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. It can be
used for the protection of industrial control network, RS422/485
interface, special line, automatic control and instrument line,
data line and telephone equipment, fax machine and other equipment.
It can also be used for the protection of sensors and two
instruments in the current ring. The product is protected from
transients, such as induced lightning current, surge voltage,
electrostatic interference, radiation interference and internal
overvoltage.
Use of attention
1. when installing, make sure that the "one" screw is
installed in place, making the line combination firmly. If the
installation is finished, the multimeter can be used to test
whether the signal lines are connected. Do not install SPD on live
line, otherwise it may damage SPD and equipment to be protected.
2. 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 shielded line of the signal can be directly
connected to the grounding terminal.
3. screw on the terminal of the surge protector with a
screwdriver. First, the system signal line is connected to the
input end of the surge protector, the output end is connected to
the protected equipment end, not the reverse, and the connection
part of the connection terminal is reliable.
Product features
1. it has self recovery function and provides multiple
protection under lightning prone environment.
2. using ultra low capacitance design, the signal
transmission characteristic is good.
3. the transmission rate is high and the frequency range is
large.

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.
