Optoisolators光隔离器
One circuit can be effectively isolated electrcially from another with the use of an optoisolator where the signal from one circuit is used to modulate an LED. The image of the signal in the form of an intensity modulated light beam is received by a phototransistor. The information is therefore transmitted without any direct electrical connection. 一个电路可以利用光隔离器有效地从另一个电路中隔离，其中一路电路的信号用于调制一个LED。信号以强度调制的光束形式被光敏晶体管接收。因此，信息可以在没有直接电气连接的情况下传输。
Note: This is just a place-holder location for future development. Very little has been done with it to date. 注意：这只是为未来开发预留的位置。截至目前，这里几乎没有任何进展。
