RS485 control signal, lightning protector, 5v/12v/24V twisted pair,
signal surge arrester, surge protector.
Product introduction
The control signal lightning arrester adopts the multistage
protection circuit, which uses the latest high speed surge
protection period, the reaction speed is fast, the output residual
pressure is low, the transmission performance is superior, the
product selects the metal shell, the seal is good, has the
dust-proof, anti-corrosion function, the interface adopts the 3pin
line terminal, installs in series, restraining the line The high
pressure surge protects the rear end equipment from overvoltage
damage.
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. identify the input / output interface identifier of the
lightning protector, input the external line and output the
connection device.
3. 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.
Product features
1. insertion loss is low to ensure that the line is unblocked.
2. the transmission rate is high and the frequency range is large.
3. low capacitance, inductance design, superior transmission
performance

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.
