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

也可以通过配另一个光绝缘体路单DS2423数器B的输出端，来监测个阻负载。

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).

大约十年前，我一个简单路，包括按全波模拟乘法器桥排列的四个光耦（图1）。
