　　该方案主要是通过市电转化成上百瓦的24V直流电压的开关电源集中给多个功能板卡供电，每个板卡具有现场设备的检测与执行功能，并且还集中了ADC信号采集、MCU的信号处理、过程控制，并能够实现强大的通讯功能，以便于进行实时操作。
　　供电方式：
　　24V通过前级滤波后通过隔离转化为24V与5V;
　　5V主要是给功能电路供电，例如MCU、看门狗，以及转化成±15V后给后端的ADC信号采集芯片供电;
　　5V通过隔离后给一些通讯芯片供电，如485等;
　　24V主要是给现场设备供电，如传感器、校准仪等;
　　方案特点：
　　该产品具有分散控制、集中操作、分级管理、配置灵活以及组态方便等优点;产品方便安装;通过高速MCU处理采集信息与响应速度快，能够体现DCS的速度性与灵敏性;采用分布式控制还可以实现高可靠性，这一点在工业应用中尤为重要。
