光耦隔离就是采用光耦合器进行隔离，光耦合器的结构相当于把发光二极管和光敏（三极）管封装在一起。发光二极管把输入的电信号转换为光信号传给光敏管转换为电信号输出，由于没有直接的电气连接，这样既耦合传输了信号，又有隔离作用。只要光耦合器质量好，电路参数设计合理，一般故障少见。如果系统中出现异常，使输入、输出两侧的电位差超过光耦合器所能承受的电压，就会使之被击穿损坏。
可以认为是一个发光二极管和一个光电二极管或三极管封装到一起。可以实现信号的完全电气隔离。在信号采集系统中广泛采用。
光耦是通电使发光二极管发光，光敏二极管接受光导通的器件。其好处输入和输出是隔离的，就象变压器一样。6N137和6N138是光耦8脚IC，具体参数搜索一下即可光偶隔离器的缺点是尺寸太大。
