Pictorial schematic diagrams, or pictorial circuit diagrams are basically the same thing with the exact identical purpose, but they use images of components inside the circuit instead of symbols. Again, here is the same precise circuit (almost except a controller was added and they're utilizing conductors L1 and L3 rather than L1 and L2.
Consider it in this way; a circuit structure is any sort of diagram that demonstrates how a circuit functions where the most important goal is that the appropriate wiring of elements and their relationship to each other rather than physical location relative to each other or intending prototypes. Nonetheless, in some uses classifying diagrams can be difficult so choose this as overall advice. I have found this is particularly true when working with much more complicated circuits and electronic equipment. I'm likely to work with a simpler but average industrial circuit since these circuit set ups are the exact same, but where you're able to observe how each sort of diagram shows the operation of the circuit in their own ways.
Here is a variant of a design diagram called a ladder design. The principal intention of this diagram will be to show the logic (referring to electric management ) of a circuit board. This really is the one that I mainly come across in my own line of work, and it is extremely effective for troubleshooting issues or learning the way the circuit functions. Some circuits are so huge that many kinds of schematic diagrams have to be read in increments from book form (generally with coded numbers so info can be simpler found). Again, here is the exact same exact circuit because the first two weeks, but considering it in ladder type.
Right, Less mess? I have enough info in every one these diagrams to know precisely what this circuit will do and also where to look for problems. Hope this helps. ( Note: don't confuse circuit or schematic diagrams with wiring diagrams; wiring diagrams will often demonstrate pictures of elements like the pictorial, and the way the entire or part of a circuit is wired. The distinction is that wiring diagrams generally put an emphasis on actual physical place of necessary components relative to each other that basically tell a layman Just What to do about the wiring)
A schematic diagram refers to a particular sort of circuit structure which utilizes standard electrical/electronic symbols instead of pictures to demonstrate how a circuit (or part of it) functions. Below is a normal 3-wire motor controller circuit utilizing a typical momentary halt - start pushbutton channel utilizing a schematic diagram. (Momentary here means the button/switch you trigger will go back to its default position once you let go of it, usually by a spring which compels the button/switch to get this done.)
Here's another schematic diagram demonstrating exactly the identical circuit, components and connections and it looks different but they both fall into the same category.
