　　隔离器是一种采用线性光耦隔离原理的设备，用于将输入信号进行转换输出。其特点在于输入、输出和工作电源三者相互隔离，特别适合与需要电隔离的设备仪表配用。隔离器又名信号隔离器，是工业控制系统中重要的组成部分。

　　在工业生产过程中，FOXBORO FBI10E 实现监视和控制需要使用各种自动化仪表、控制系统和执行机构，它们之间的信号传输既包含微弱到毫伏级、微安级的小信号，也有几十伏，甚至数千伏、数百安培的大信号，既有低频直流信号，也有高频脉冲信号等。由于这些信号的复杂性，仪表和设备之间的信号传输可能会互相干扰，导致系统不稳定甚至误操作。其中，一个重要的因素是由于仪表和设备之间的信号参考点之间存在电势差，形成“接地环路”，造成信号传输过程中失真。隔离器的作用就在于断开过程环路，同时又不影响过程信号的正常传输，从而解决接地环路问题。

　　Isolator is a device that uses the principle of linear optocoupler isolation to convert the input signal to the output. Its characteristic is that the input, output and working power supply are isolated from each other, especially suitable for use with equipment and meters that need electrical isolation. The isolator, also known as the signal isolator, is an important part of the industrial control system.

　　In the industrial production process, FOXBORO FBI10E to achieve monitoring and control requires the use of a variety of automated instruments, control systems and actuators, the signal transmission between them contains both weak to millivolt level, microampere level of small signals, there are tens of volts, even thousands of volts, hundreds of amperes of large signals, both low-frequency DC signals, but also high-frequency pulse signals. Due to the complexity of these signals, signal transmission between instruments and devices may interfere with each other, leading to system instability and even misoperation. Among them, an important factor is that there is a potential difference between the signal reference points between the instrument and the device, forming a "ground loop", resulting in distortion during signal transmission. The role of the isolator is to disconnect the process loop without affecting the normal transmission of the process signal, so as to solve the ground loop problem.
