1.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).

1.大约十年前，我设计了一个简单路，括按全波模拟乘法器桥列的四个光耦（图1）。

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

2.也可以通一个光绝缘体路到单DS2423计数器B的输出端，来监测两个阻负载。
