 <description><![CDATA[加一个高速光耦，即可，因我已改过一个设备，伺服输出是5V变化，而PLC 是24V输入。中间加了一个高速光耦，用了二年有余，没出现任何问题。]]></description>

 <description><![CDATA[谢谢这么多人帮忙。因为是伺服编码器输出的。信号频率肯定很高了。就是固态继电器都不行，中间继电器肯定不行了。肯定得三极管。]]></description>

 <description><![CDATA[帮你查了一下，都是NPN管，9013有点危险，用9014应该没问题。主要是Vceo 有问题
具体参数自己看：

 <description><![CDATA[一般你需要看集电极与基极、发射极的耐压，确保2倍以上。同时确保集电极电流足够大，还有频率。9013是npn型，90系列只有9012、9015是pnp型。电压是够了，你需要确认电流、频率值。]]></description>
