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

Product specification

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.
