A1SY60E三菱全系列现货、系统受干扰时，常会遇到以下几种主要干扰现象：
(1)系统发指令时，电机无规则地转动；
(2)信号等于零时，数字显示表数值乱跳；
(3)传感器工作时，PLC采集过来的信号与实际参数所对应的信号值不吻合，且误差值是随机的、无规律的；
(4)与交流伺服系统共用同一电源(如显示器等)工作不正常。
5、怎样才能更好、更简单解决PLC系统干扰？
(1)理想状态下是选用隔离性能较好的设备、选用优良的电源、动力线和信号线走线、电源接地要更加合理等等，但是需要不同设备厂商共同协作才能完成，很难做到，而且成本较高。
(2)利用模拟信号隔离器，有称作信号变送器、属于信号调理的范畴。其主要起抗干扰作用。正因为它有特强的抗干扰能力所以在自动化控制系统中应用非常广泛。尤其对于复杂的工业现场，控制程序越来越复杂，信号隔离器对各种模拟量信号进行输入、输出、电源三端隔离，的确是当今自动化控制系统中抗干扰的有效措施。
6、为什么解决PLC系统干扰*信号隔离器呢？
(1)使用简单方便、可靠，成本低廉，可同时解决多种干扰。
(2)可大量减轻设计人员、系统调试人员工作量，即使复杂的系统在普通的设计人员手里，也会变的非常稳定可靠。
7、信号隔离器工作原理是什么？
首先将PLC接收的信号，通过半导体器件调制变换，然后通过光感或磁感器件进行隔离转换，然后再进行解调变换回隔离前原信号或不同信号，同时对隔离后信号的供电电源进行隔离处理。保证变换后的信号、电源、地之间*独立。
8、现在市场有那么多的隔离器，价格参差不齐，该怎么选择呢？
隔离器位于二个系统通道之间，所以选择隔离器首先要确定输入输出功能，同时要使隔离器输入输出模式（电压型、电流型、环路供电型等）适应前后端通道接口模式。此外尚有精度﹑功耗﹑噪音﹑绝缘强度﹑总线通讯功能等许多重要参数涉及产品性能，例如：噪音与精度有关、功耗热量与可靠性有关，这些需要使用者慎选。之，适用、可靠、产品是选择隔离器的主要原则。
