光耦合器件是七十年代发展起来的一种新型元器件。它是将发光元件和受光元件密封在同一管壳中,以光作媒介来传递信号。这种器件,上海电子电器元件厂现已批量生产。光耦合器件的主要功能是将电信号转换
Optical coupling device is developed in the seventies a new type of components. It is the light-emitting components and light-emitting components sealed in the same package, the light as a medium to transmit signals. This device, Shanghai Electronic Components Factory is now in volume production. The main function of the optical coupling device is to convert electrical signals
