IEC 60381-2:1978 ed1.0

Действует
Analogue signals for process control systems. Part 2: Direct voltage signals — 5 стр.
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.
