四、输出特性

  测量Y214S的输出特性。  给输出串联一个 50欧姆的功率电阻， 连接到 8V的工作电压。  测量不同输入发光二极管电流下， 输出电阻上的电压，  进而也能够知道对应的电流大小。   使用 DH1766 提供不同的输入电压。  可以看到， 当出现红外二极管输入电流大于 1mA， 负载上的电压就达到了5.5V， 对应的输出电流大约为 110mA。 接下来随着输入电流增加， 输出电流似乎已经达到了饱和。  这说明固态继电器输出MOS管上的偏置电压似乎是一个恒定值， 也使得输出呈现饱和状态。

▲ 图1.4.1 输入电流与输出50欧姆电阻上的电压

  下面将输入红外发光二极管电流固定在30mA左右，  测量输出的伏安特性。  通过50欧姆的电阻上的电压测量输出电流。  使用另外一个万用表测量 输出端口的电压。 将工作电压从 0V 提高的 10V。  得到了Y214S的输出伏安特性。 它近似一个电阻。  在 1V之前， 它近似 25欧姆的电阻。  在2V之前， 近似为 20欧姆的电阻。

▲ 图1.4.2 输出电压与电流

  根据Y214S内部的结构，  它的输出呈现对称性。 下面将输出电压极性对调。 测量输出的反方向的伏安特性。  可以看到， 正反两个方向的特性基本上是重叠的。  这样， 这个电子继电器输出没有极性。 只是现在看来， 它的内阻有点大了。
