ELECTRONIC DIAGRAMS, PRINTS, AND SCHEMATICS
Electronic Diagrams and Schematics
Figure 14 provides a sample illustration of how the various types of drawings can be combined.
In this example, mechanical symbols are used to represent the process system and the valves
controlled by the electrical circuit; electrical single line symbols are used to show the solenoid
relays and contacts used in the system; and electronic block symbols are used for the controllers,
summers, I/P converter, and bistables.
