The host computer and sampling units were separated electrically by adding photocoupler circuits to RS 485 bus interfaces.
由于在RS - 485总线上加入了光电隔离电路,主计算机和各个数据采集单元电气上完全隔离。
A novel design method of linear isolated amplifier is introduced, which consists of operation amplifier LF353 and photocoupler TLP521.
应用普通运算放大器LF353和普通光耦TLP521设计了一种新型线性隔离放大器。
The selection of components for a two-way photocoupler with high speed and high gain is described as well as its structure, operating principle, basic characterizations and applications.
