TRSS-485 control signal surge protection device
Model: TRSS-485
Color: white / red
Verification: CE
product description
Control signal lightning protection device: used for transmission protection of sensitive control signals, widely used in computer communication systems, monitoring and control systems, access control intercom systems, automatic control systems, data transmission of security systems, etc. Surge protection. Typical for computer RS485, RS422RS232 and other communication serial ports. Protect it from lightning induced voltages, grid voltage fluctuations, electrostatic discharges, and shock surge voltages.
working principle
The control signal surge protector is connected in series with the front end of the protected device. When the transmission line is subjected to induced lightning and other transient overvoltage surges, the inrush current is discharged to the earth through the protection branch of the surge protector, and the output is output. The voltage is clamped to the voltage range allowed by the device, thus ensuring the safety of the operating equipment.

Use attention
1. Look for the input/output interface identification of the lightning arrester, and input the external line and output connection equipment;
2. The grounding wire stress should be short, thick and straight to reduce the influence of distributed inductance on the discharge of lightning pulse electromagnetic pulse capability.
3. Industrial control signal lightning protection grounding should be connected to the ground through an electronic switch.
4. Connect the lightning protection device (SPD) between the line and the device port to be protected. Connect the grounding port on the SPD to the grounding grid with multiple strands of copper wire, and ensure that the grounding resistance is not more than 4 ohms.
