Pictorial design diagrams, or graphic circuit diagrams are basically the same thing with exactly the identical function, but they use images of components inside the circuit instead of symbols. Again, here's the same specific circuit (virtually except a control transformer was inserted and they're utilizing conductors L1 and L3 instead of L1 and L2.
Think of it this way; a circuit structure is any kind of diagram which illustrates the way the circuit operates where the primary goal is that the proper wiring of elements and their relationship to each other instead of physical location relative to one another or planning prototypes. Nevertheless, in some uses Assessing diagrams can be hard so take this as general information. I've found this is especially true when working with more complicated circuits and electronic equipment. I'm likely to work with a simpler but average industrial circuit since these circuit setups are the exact same, but where it is possible to observe how each sort of diagram indicates the use of the circuit in their own ways.
A design diagram refers to a particular kind of circuit design that uses standard electrical/electronic symbols instead of images to demonstrate the way the circuit (or portion of it) functions. Below is a typical 3-wire motor control circuit utilizing a standard short stop halt - start pushbutton channel working with a schematic diagram. (Momentary here means the button/switch you activate will go back to its default position once you let go of it, typically by a spring that forces the button/switch to do this.)
Here's another schematic diagram showing the identical circuit, connections and components and it seems different but they both fall into the exact same category.
Much less clutter? I have enough info in every one these diagrams to know just what this circuit will do and where to search for problems. Hope this helps. ( Note: don't confuse circuit or schematic diagrams with wiring diagrams; wiring diagrams will typically demonstrate pictures of elements like the pictorial, and also the way the whole or part of a circuit will be wired. The difference is that wiring diagrams generally place an emphasis on real physical location of necessary components relative to each individual that essentially tell a layman Just What to do concerning the wiring)
Here is a variant of a diagram. The principle intention of this diagram is to show the logic (speaking to electrical control) of a circuit board. This diagram is the one that I mostly come across in my own line of work, and it's very successful for troubleshooting issues or learning the way the circuit works. Some frequencies are so huge that many kinds of schematic diagrams need to be recorded in increments in novel form (normally with coded numbers so info can be simpler located ). Again, here's the identical exact circuit because the first two, however considering it in ladder shape.
