IEC 60381-2 Ed. 1.0 b:1978, Analogue signals for process control systems. Part 2: Direct voltage signals

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. This title may contain less than 24 pages of technical content.
