Here's another schematic diagram showing precisely exactly the identical circuit, connections and components and it looks different but they both fall into exactly the identical category.
A schematic diagram refers to a particular sort of circuit structure that uses standard electrical/electronic symbols instead of images to demonstrate the way the circuit (or portion of it) works. Below is a normal 3-wire motor controller circuit employing a standard short stop stop - start pushbutton channel using a schematic diagram. (Momentary here means the button/switch you trigger will return to its default place once you physically let go of this, typically by a spring which forces the button/switch to do this.)
Pictorial design diagrams, or graphic circuit diagrams are essentially the exact same thing with exactly the same function, but they use images of components within the circuit rather than symbols. Again, here's the same exact circuit (virtually except a controller was added and they're using conductors L1 and L3 rather than L1 and L2.
Think of it in this way; a circuit diagram is any type of diagram that demonstrates the way the circuit functions where the main objective is that the appropriate wiring of elements and their connection to each other rather than physical place relative to one another or planning prototypes. Nevertheless, in some applications classifying diagrams can be challenging so take this as general advice. I've discovered this is particularly true when dealing with much more complex circuits and electronics. I'm going to work with a more straightforward but average industrial circuit because these circuit set ups are the exact same, but where you're able to see how each type of diagram indicates the purpose of the circuit in their own manners.
Much less clutter, right? I have enough information in each one of these diagrams to know exactly what this circuit does and where to start looking for problems. Hope that this helps. ( Note: don't confuse circuit or schematic diagrams with wiring diagrams; wiring diagrams will usually demonstrate images of elements like the pictorial, and how the entire or part of a circuit will be wired. The difference is that wiring diagrams generally place an emphasis on actual physical place of necessary components relative to each other that basically tell a layman exactly what to do concerning the wiring)
Here is a variant of a diagram known as a ladder structure. The major purpose of this diagram will be to show the logic (referring to electrical management ) of a circuit board. This diagram is the one I mainly come across in my line of work, and it is extremely effective for troubleshooting problems or learning how a circuit works. Some frequencies are so enormous that many types of schematic diagrams have to be recorded in increments in book form (normally with coded numbers so that information can be simpler located ). Again, here's the exact same precise circuit as the first 2, however looking at it in ladder form.
