RS485 Rail Type Signal Surge Protector Automatic Signal Surge Protection Device

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

Product specification

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.
