optoisolator

You can also monitor two independent loads by attaching a second optoisolator circuit to the Counter B input of a single DS2423.

也可以通一光绝缘体电路到单DS2423计数器B输出端，来监测两电阻负载。

A decade or so ago, I designed a simple circuit that included a quad optoisolator arranged in a full-wave analog-multiplier bridge (Figure 1).

大十年前，我设计了一简单电路，包括按全波模拟乘法器电桥排列光耦（图1）。
