Here is a technical version of a diagram. The primary goal of this diagram will be to show the logic (referring to electrical control) of a circuit. This diagram is the one that I mostly encounter in my line of work, and it is very successful for troubleshooting problems or learning how a circuit functions. Some circuits are so enormous that most types of schematic diagrams have to be recorded in increments from novel form (generally with coded numbers so that information can be simpler located ). Again, here's the same specific circuit because the first 2, however looking at it in ladder form.
Pictorial schematic diagrams, or pictorial circuit diagrams are essentially the identical thing with exactly the identical purpose, but they use pictures of components within the circuit rather than symbols. Again, here's the identical precise circuit (almost except a controller was inserted and they are using conductors L1 and L3 instead of L1 and L2.
A schematic diagram refers to a particular kind of circuit design which utilizes standard electrical/electronic symbols instead of pictures to show the way the circuit (or portion of it) functions. Below is a standard 3-wire motor control circuit utilizing a normal short stop stop - start pushbutton channel employing a schematic diagram. (Momentary here means the button/switch you trigger will return to its default place once you let go of it, typically by a spring that forces the button/switch to do this.)
Here's another schematic diagram demonstrating precisely the identical circuit, components and connections and it appears different but they fall into precisely the identical category.
Consider it this way; a circuit structure is any type of diagram that illustrates the way the circuit operates where the main purpose is that the proper wiring of elements and their connection to each other instead of physical location relative to each other or intending prototypes. Nevertheless, in some uses classifying diagrams can be challenging so take this as general information. I have discovered this is especially true when dealing with more complex circuits and electronic equipment. I'm going to use a simpler but average industrial circuit because these circuit set ups are the exact same, but yet where you can observe how each type of diagram indicates the purpose of the circuit in their own ways.
Less mess, right? I've got enough information in all these diagrams to know exactly what this circuit does and where to search for issues. Hope this helps. ( Note: don't confuse lecture or circuit diagrams together with wiring diagrams; wiring diagrams will often show images of elements like the pictorial, and also the way the whole or portion of a circuit has been wired. The difference is that wiring diagrams generally place an emphasis on real physical location of necessary components relative to each other that essentially tell a layman Just What to do concerning the wiring)
