GB/T 4728.13-1996 Graphical symbols for electrical schematics Part 13: Analog components

This standard specifies the graphic symbols for drawing analog components that work on analog quantities and/or produce analog quantity functions. The symbols specified in this standard are applicable to applications in the electrical field; however, many of them can also be used in non-electrical fields, such as pneumatic, hydraulic and mechanical.

GB/T 4728.13-1996
This standard is a revision of GB4728.13-85 "Graphic Symbols for Electrical Diagrams - Analog Units" based on IEC617-13:1993 "Graphic Symbols for Electrical Schematics - Part 13: Analog Components" of the International Electrotechnical Commission. It is equivalent to the international standard in terms of technical content and writing rules.
This standard is difficult to compare with the previous version. The difference is that: voltage regulators and voltage comparators are added, and detailed provisions are made for the relevant limiting symbols of input, output and other connections. There are slight changes in the graphic symbols for electronic switches, track holders, analog comparators, etc., and typical application examples are given in the graphic symbols.
When equivalently adopting IEC617-13, considering the actual situation in my country, its Appendix A "Index by French Alphabet" is deleted, and Appendix B "Index of limiting symbols arranged in English alphabetical order" and Appendix C "Index by device model in the example" are retained, and changed to Appendix A and Appendix B of this standard.
Through the revision of this standard, the drawing rules of analog component graphic symbols are better unified to meet the needs of international and domestic trade, technology and economic exchanges.

IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization composed of all national electrotechnical committees (IEC national committees). The goal of IEC is to promote international cooperation on standardization issues related to electrical and electronic fields. For this purpose and other activities, IEC publishes international standards, and the work of standard preparation is entrusted to technical committees: any IEC national committee that is interested in the content it studies can participate in the preparation work. International organizations, governmental and non-governmental organizations that have relations with IEC can also participate in the preparation work. IEC and the International Organization for Standardization (ISO) work closely together under the terms agreed upon by the two organizations. 2) IEC's formal decisions or agreements on technical materials prepared by technical committees on behalf of all national committees that have a special interest in them reflect the international consensus on the issues studied as closely as possible. 3) They are published in the form of standards, technical reports or guides as recommendations for international use and are accepted by the National Committees in this case.
4) In order to promote international unification, the National Committees of the IEC have the task of applying IEC International Standards to national or regional standards to the greatest extent possible. Any differences between IEC standards and corresponding national or regional standards should be clearly indicated in the latter. International Standard IEC617-13 was prepared by 3A Subcommittee "Graphic Symbols" of IEC Technical Committee 3 "Documentation and Graphic Symbols". The second edition of IEC617-13 cancels and replaces the first edition published in 1978. The content of this standard is based on the following documents (except the first edition of IEC617-13) Draft International Standard

The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard was published, the versions shown were valid. All standards are subject to revision, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB3101-93 General principles for quantities, units and symbols (e9VIS031-0: 1992) GB4728.2-84 Graphical symbols for electrical diagrams Symbol elements, qualifiers and other commonly used symbols (idtIFC617-2: 1983)

3 General instructions
3.1 The signal level transmitted on the analog lead is continuous rather than two logical states. The structure and combination of its boxes, as well as the markings and associated markings, shall also comply with the general rules of GB/T4728.12. In order to facilitate the layout of the diagram or to better express the structure of the device, when the information flow is clear or there is a clear indication, the input terminal may also be drawn on the right and the output terminal on the left. 3.2 In some figures, the lowercase letters that appear outside the box are not part of the symbol and are added only to identify the input and output in the description.
3.3 The weighting coefficient of the input signal is represented by a number with a positive or negative sign, marked at the corresponding input terminal in the box. In this standard, Wi, W2,, W, are all understood as values ​​with appropriate signs used to represent the weighting coefficient. The symbol can be +1 or -1. When the weighting coefficient is +1 or -1, for example, a simple non-inverting or inverting input, the number 1 can be omitted. 3.4 In GB3101--93, the text symbols of quantities are in italics. However, in simplified diagrams, traditional Chinese characters are usually used. In this standard, all symbols and simplified diagrams are in traditional Chinese characters.
Approved by the State Administration of Technical Supervision on December 18, 1996 39.
Implemented on July 1, 1997
GB/T 4728.13--1996
3.5 In this standard, the letters V and v are still retained as the representative symbols of the physical quantity voltage, because these symbols are still widely used in the field of semiconductor devices and general electronics. Therefore, in the graphic symbols drawn according to this standard, V and are equivalent to U and u, including the symbols used for qualifiers that can be replaced with each other. 3.6 In this standard, "" is used as phase (phase difference). "" and "Φ\ are equivalent. 3.7 In most cases, the examples listed in this standard are based on existing commercial devices. Therefore, the model and lead terminal code (technically indicating the package type) are marked. The model means that the device is a product of a specific manufacturer. This is done to avoid the uncertainty caused by the functional differences of devices with the same category number produced by different manufacturers. 3.8 Some symbols in this standard have external connections or external networks. The functions indicated on the symbols can only be realized when these external connections or external networks exist.
3.9 In this standard, if binary inputs or outputs appear and no polarity indicators are used, they are all Set to positive logic convention. 3.10 Marking combination symbols (see 54.6 in GB/T4728.12-1996) can be applied to a group of connecting lines with the same, adjacent and related marking parts.
Part 2 Qualifying symbols related to input, output and other connections 4 Qualifying symbols indicating signal types
When it is necessary to distinguish between analog signals and digital signals, gates or # can be used (see symbols with serial numbers 02-17-12 and 02-17-13 in GB4728.2-84). When it is confusing whether the function or signal is analog or digital, they can also be added to the general qualifier, or in accordance with GB/T4728. Serial number

If the Mm Input {Mm Output] is in its internal \1\ state, any input affected by this Mm Input [Mm Output] will function as usual on the device, and any output affected by this Mm Input [Mm Output] will be in its normal logic state or Analog signal level. In other words, both input and output are selected
If Mm input (Mm output] is in the internal o state, its effect on input and output is as follows: Any input affected by this Mm input [Mm output] has no effect on the function of the component
