工业环境空间中的*电磁场和高电压、大电流的通断将会对PLC产生强烈的干扰,由于现场条件的限制,有时几百米长的强电电缆和PLC的低压控制电缆只能敷设在同一电缆沟内,强电干扰在输入线上产生的感应电压和电流相当大,足以使PLC输入端的光电耦合器中的发光二极管发光,光电耦合器的隔离作用失效,使PLC产生误动作。在这种情况下,对于用长线引入PLC的开关量信号,可以用小型继电器来隔离,光电耦合器中发光二极管的zui小工作电流仅为3mA左右,而小型继电器的线圈吸和电流为几十毫安,强电干扰信号通过电磁感应产生的能量不可能使隔离用的继电器吸合。有的系统需要使用外部信号的多对触点,例如一对触点用于指示灯,并使用继电器转接输入信号,这样既能提供多对触点,又实现了对强电干扰信号的隔离。
