（3）信号隔离

　　对于模拟量输入输出（AI/AO）回路，要防止从现场来的强电串入卡件，以及就地设备与DCS系统不共地可能产生的电势差。重要回路应该采取信号隔离器。对于数字量输入输出（DI/DO）回路，常用的解决方法就是对DI/DO信号采用继电器隔离。比如对于一个马达控制关反馈输入回路：现场的常开接点闭合时，继电器线圈带电，输出接点闭合，接点信号引入开关量采集卡件。这样，强电就不会串入卡件的信号回路，发生故障时，也主要检修隔离的外回路。采用继电器进行信号隔离的缺点是：需要给外回路添加供电回路；采用电磁隔离和光电隔离技术的开关量隔离器，可以减少为外回路供电的工作量。

　　（3）大型电气设备引起的干扰

　　在大型电气设备启动和开关装置动作频繁的地方，电动机的启动、开关的闭合产生的火花会在其周围产生很大的交变磁场．这些交变磁场既可以通过在信号电缆上耦合产生干扰，也可能通过在电源电缆上耦合产生高频干扰，这些干扰如果超过容许范围，也会影响
