Industrial control signal, RS485 rail type lightning arrester,
automatic signal surge protection device.
Brief introduction
The lightning protection device of the control signal is used for
lightning protection of the data communication system. It can
protect four signal lines or two pairs of twisted pair information
lines, provide high energy coarse level protection and low energy
fine protection for data lines, and provide fine differential
protection and ground common mode protection for 1, 2 and 3, 4 two
lines, respectively, so as to effectively absorb and transfer. The
energy impact caused by lightning and surge will lead the energy
into the earth through the grounding cable, so that the sensitive
electronic devices will not be infringed.
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. the low attenuation and return loss in the wide frequency range
ensure that the lightning arrester does not affect the system
performance.
2. advanced production process and beautiful appearance
3. installation is easy and easy to use

Use of attention
1. connect the lightning protector (SPD) between the line and the
equipment port to be protected. The grounding port on the SPD will
be connected to the ground network with multiple copper conductors,
and the grounding resistance should not be greater than 4 ohms.
2. 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.
3. temperature: -40 to 70 DEG C; relative humidity: less than 95%;
atmospheric pressure: 70kPa ~ 106 kPa.
