PLC：Programmable logic Controller
全称是可编程控制器，是由主控芯片和外围电路构成的一个应用系统，可以通过程序预先编写指令流程，实现特定功能，通常使用在自动化、工控等领域。其特点是高稳定性，方便编程、使用。
The full name is a programmable controller which is an application system composed of the main control chip and peripheral circuits and can pre-write the instruction process through the program to achieve specific functions usually used in automation industrial control and other fields. It is characterized by high stability easy to program and use.
问：PLC为什么需要搭配隔离栅/隔离器使用？
Q: Why does the PLC need to be used with an isolation barrier/isolator?
答：因为现场设备的工作环境比较恶劣，假如到PLC的信号传感线破皮与其他不同电压的线路连接或同时短接到设备上会有强电进plc输入端口，造成整块模块被烧，损失较大。而加上信号隔离器隔离如果出现此种情况则只会损坏隔离器而不会损伤plc。另外就是防干扰，稳定信号。
A: Because the working environment of the field device is relatively harsh if the signal sensing line to the PLC is broken and connected to other lines of different voltages or short-circuited to the device at the same time there will be a strong power into the PLC input port resulting in the entire module being burned and the loss is larger. If this situation occurs the additional signal isolator isolation will only damage the isolator and will not damage the plc. The other is anti-interference stable signal.

隔离栅、隔离器作用
实际应用中，控制系统的信号干扰问题非常严重。
采用信号隔离栅/隔离器的接线方式
•切断了传导干扰的传播途径，
•减小设备直接连接的接地环路带来的信号失真，
•提高了模拟信号抗干扰的能力
一旦发生事故造成器件损坏，更换隔离器比更换PLC/DCS模块更加省时省经费。因此建议还是需要根据实际情况确定安装位置。
In practical applications the signal interference problem of the control system is very serious.
Wiring method using signal isolation gate/isolator
• Cut off the transmission route of conducted interference
• Reduce signal distortion caused by ground loops where the device is directly connected
• Improved the ability of analog signals to resist interference
In the event of an accident that causes damage to the device replacing the isolator is more time-saving and cost-saving than replacing the PLC/DCS module. Therefore it is recommended that the installation location still need to be determined according to the actual situation.
