C Series Ultra Thin Signal SPD

• 

In today's fast-paced world of information technology, electronic devices are being used in increasingly diverse applications. However, their lower operating voltage and reduced surge tolerance make them particularly sensitive to transient overvoltage in system signals. This is especially true in the field of automation, which involves a large amount of signal transmission, requiring the installation of numerous surge protective devices for transient overvoltage protection.

While ensuring the surge protection performance of SPDs is critical, their size is also becoming increasingly important. The more SPDs that can be installed in a single control cabinet, the fewer cabinets are needed, resulting in lower overall costs.

Signal SPDprotects signal devices (e.g. PLC, DCS, SCADA, transmitter, flow meter, solenoid valve) from lightning, which is applied to signals such as AI/ AO/ DI/ DO, RS485/ RS232/ RS422, RTD and TC etc..

FAQ of C Series Ultra Thin Signal SPD

Q

What is the function of an SPD?

A

When lightning strikes, high-power equipment starts and stops, or electrostatic discharge occurs, transient overvoltage (surge) is generated, causing equipment damage. SPD (Surge Protective Device) is the abbreviation for surge protection device. SPD is installed at the front end of the equipment being protected. When a surge occurs, the SPD can quickly conduct electricity and discharge the surge to the ground, limiting the voltage to a safe level, thereby protecting the equipment at the back end.

Q

Should SPD be installed?

Established in 2002, CHENZHUhas developed as a manufacturing center that is able to manufacture 4 main categories of the product (Isolated Barrier, Signal Conditioner, Surge Protective Device, Safety Relay) with 18 ranges of series.
