RS485 signal protector, signal surge protector, control signal arrester, industrial application.
Product introduction
Control signal lightning arrester: used for transmission and
protection of sensitive control signals, widely used in the
lightning protection and surge protection of various control signal
lines, such as computer communication system, monitoring control
system, door control system, automatic control system, data
transmission of security system and so on. It is typically used for
communication serial ports such as computers RS485 and RS422RS232.
It is protected from damage caused by lightning induced voltage,
grid voltage fluctuation, electrostatic discharge and impact
voltage.

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. 1 system signal lightning arrester can be installed in the
LPZ0-1 area or directly connected to the front end of the protected
equipment (or system), and the closer the better from the protected
equipment (or system).
2. "IN" connects the lead end, "OUT" connects the protected
device (or system) end, "1" and "3" as a signal channel, "2" and
"4" as a signal channel. When installing, the two ends must be laid
separately, and not be tied together to prevent the two induction.
3. the lightning arrester is not required for long-term
maintenance without longer maintenance. It only needs the routine
maintenance of the system. In the process of use, the signal
transmission is problem, the signal transmission is restored to
normal after the surge protector is replaced, indicating that the
surge protector has been damaged and needs to be repaired or
replaced.
Product features
1. insertion loss is low to ensure that the line is
unblocked.
2. the coefficient of standing wave is small and the range
of working frequency is wide
3. it has three protection functions: overcurrent,
overvoltage and clamping.
