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.
