硬件措施：

主要模块均采用大规模或超大规模集成电路，大量开关动作由无触点的电子存储器完成，I/O系统设计有完善的通道保护和信号调理电路。
①    屏蔽——对电源变压器、CPU、编程器等主要部件，采用导电、导磁良好的材料进行屏蔽，以防外界干扰。
②    滤波——对供电系统及输入线路采用多种形式的滤波，如LC或π型滤波网络，以消除或抑制高频干扰，也削弱了各种模块之间的相互影响。
③    电源调整与保护——对微处理器这个核心部件所需的+5V电源，采用多级滤波，并用集成电压调整器进行调整，以适应交流电网的波动和过电压、欠电压的影响。
④    隔离——在微处理器与I/O电路之间，采用光电隔离措施，有效地隔离I/O接口与CPU之间电的，减少故障和误动作；各I/O口之间亦彼此隔离。
⑤    采用模块式结构——这种结构有助于在故障情况下短时修复。一旦查出某一模块出现故障，能迅速更换，使系统恢复正常工作；同时也有助于加快查找故障原因。
