 <description><![CDATA[我在这里谢谢以上各位了，特别是三楼！是的，我查过了，负载（亚德克的电磁阀4V110-06-DC24）有问题，短路了！可是这电磁阀的功率很小的哦，才2.5w。按说我直接驱动是一点问题都没有的，我现在就不明白是先电磁阀短路，还是先PLC的Y3点粘连，两者到底谁是罪魁祸首？或者是我PLC程序有问题！（不好意思，PLC编程我是刚学的 ..]]></description>

 <description><![CDATA[[quote]引用第2楼seeyou于2011-12-17 00:46发表的&nbsp;&nbsp;:
那是因为Y3带的负载远超过了它触点的负荷能力，或是Y3负载有短路现象。还有可能是Y3负载电压很高引起触点打火。

 <description><![CDATA[你是在通电情况下测还是断电情况下测电阻的？如果通电情况下可能是内部接通了Y3有输出，如果断电可能是光耦被击穿了！如果外接负载可能与负载电阻有关！]]></description>
