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.

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.

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.
