Signal & Data SPD
The CSRS-485 series surge protective device can be used for lightning protection and surge impact prevention in RS-485 serial communication networks. They feature standard terminal-type interfaces and can be installed on the rails of the cabinet. Each serial port of the communication devices should be equipped with one of these surge protective devices.
The CSMS-RJ45 series network surge protective devices can be used for lightning protection of the four lines of Ethernet communication network ports. They adopt the standard RJ45 network interface and are designed in accordance with IEC standards. They are suitable for installation between the input and output of various communication network devices.

FAQ
Where should Ethernet SPD be installed?
Ethernet SPD should be installed near the protected equipment, at cable entry points, or at both ends of long outdoor network cable runs when necessary.
How do I choose Ethernet SPD?
You should confirm the network speed, PoE requirement, connector type, cable route, installation environment, and whether the equipment is installed outdoors.
Does PoE equipment need surge protection?
Yes. PoE equipment, especially outdoor IP cameras and access points, can be exposed to lightning-induced surges through long network cables.
Does RS485 need surge protection?
Yes. RS485 lines are often used in outdoor or industrial environments and may be exposed to lightning-induced surges, ground potential differences, and switching interference. RS485 SPD can help protect communication devices.
How do I choose the correct signal SPD?
You need to confirm the signal type, operating voltage, number of wires, communication protocol, transmission rate, and installation environment.
Can signal SPD affect communication quality?
If selected correctly, signal SPD should not affect communication quality. The SPD should match the signal type, working voltage, bandwidth, and communication protocol.
How is signal SPD different from power SPD?
Power surge protectors are used for electrical equipment, while signal surge protectors are designed to protect signal transmission and processing devices connected to signal lines (low-voltage signal equipment). Signal surge protectors must take into account operating voltage, signal frequency, data transmission rate, and line impedance. Power surge protectors must consider operating voltage, installation location, and the maximum voltage tolerance of the protected electrical equipment.
Can power SPD protect signal lines?
No. Power SPDs and Signal & Data SPDs are designed for different circuits. Power SPDs protect power lines, while Signal & Data SPDs protect low-voltage communication and control lines.
What applications use Signal & Data SPDs?
Signal & Data SPDs are used in industrial automation, telecom systems, security monitoring, CCTV systems, building automation, fire alarm systems, access control systems, and remote monitoring equipment.
What is a Signal & Data SPD?
A Signal & Data SPD is designed to protect low-voltage signal, control, and communication lines from surge voltage. It is commonly used for RS485, Ethernet, telephone lines, control lines, sensor lines, and monitoring systems.
