FAQ
What information is needed for automation SPD selection?
You need to provide power voltage, signal type, communication protocol, cable length, installation environment, grounding condition, and protected equipment type.
Where should SPD be installed in industrial control systems?
SPD should be installed at power input points, cabinet cable entry points, communication interfaces, sensor line entrances, and near sensitive control equipment.
What type of SPD is used for RS485 communication?
RS485 systems require signal SPD designed for low-voltage communication lines. The SPD should match the working voltage, number of wires, transmission speed, and communication structure.
Can surge protection protect PLC systems?
Yes. Properly selected SPD can help protect PLC power supplies, communication modules, I/O modules, and connected field devices from surge damage.
What parts of an automation system need SPD?
SPD may be needed for AC power supply lines, DC power circuits, PLC input/output lines, RS485 communication lines, sensor lines, Ethernet networks, and control cabinets.
Why do industrial automation systems need surge protection?
Industrial automation systems include PLCs, sensors, control cabinets, communication networks, and power supplies. These components are sensitive to transient overvoltage caused by switching operations, lightning-induced surges, and electrical interference.
