Scope
GB/T 22112-2008 is the English-translated version of 工业自动化仪表 接线端子的排列和标志.
GB/T 22112-2008 specifies how the connecting terminals of industrial process measurement and control instruments are numbered, arranged and marked for connection to external circuits.
It applies to panel-mounted instruments, and may be used for instruments that are not panel-mounted; it does not cover connector-type connections or instruments for special service such as explosion-protected equipment.
The numbering rules cover single terminal boards in horizontal rows, vertical columns and square matrices, parallel signal terminals, and multiple terminal boards numbered either continuously or independently with Latin letter identifiers, each illustrated by example figures.
The arrangement rules place input terminals before output terminals and positive before negative, with further requirements for earth and power supply terminals, and the marking draws on the graphical symbols of the GB/T 4728 series and the terminal identification rules of GB/T 4026.
It is published for the first time, issued on 30 June 2008 and in force since 1 January 2009. Classification: ICS 25.040.40, CCS N10. The document runs to 12 pages, delivered complete in English translation.
