适用于工业过程测量和控制系统中使用的模拟直流电压信号。lt规定了模拟直流电压信号和公共信号的范围；它还处理ripple内容。与IEC 60381-1中规定的模拟直流信号不同，模拟直流电压信号不适用于远距离传输。本标准不适用于完全在元件内使用的信号。

Applicable to analogue direct voltage signals used in industrial process measurement and control systems. lt specifies ranges of analogue direct voltage signals and the signal common; it also deals with ripple content. The analogue direct voltage signal, unlike the analogue direct current signal specified in IEC 60381-1, is not intended for transmission over long distances. This standard does not apply to signals used entirely within an element.
