Pictorial design diagrams, or graphic circuit diagrams are basically the exact identical thing with the exact identical function, but they use images of elements inside the circuit rather than symbols. Again, here's the exact precise circuit (almost except a control transformer was inserted and they are utilizing conductors L1 and L3 instead of L1 and L2.
Here's another schematic diagram demonstrating the identical circuit, components and connections and it appears different but they fall into precisely exactly the exact identical category.
A design diagram refers to a particular sort of circuit diagram that utilizes standard electrical/electronic symbols instead of images to show the way the circuit (or a part of it) works. Below is a standard 3-wire motor controller circuit using a standard momentary halt - start pushbutton channel utilizing a schematic diagram. (Momentary here means the button/switch you activate will go back to its default place once you physically let go of it, usually by a spring which compels the button/switch to do this.)
Consider it this way; a circuit structure is any sort of diagram which demonstrates the way the circuit functions where the principal objective is the proper wiring of elements and their relationship to each other instead of physical place relative to each other or intending prototypes. Nevertheless, in some applications classifying diagrams can be hard so take this as overall information. I have found this is especially true when working with more complicated circuits and electronics. I'm going to use a simpler but average industrial circuit since these circuit setups are exactly the same, but where it is possible to see how each sort of diagram shows the purpose of the circuit in their own ways.
Right, less mess? I have enough info in all of these diagrams to know exactly what this circuit does and where to search for problems. Hope that this helps. ( Note: don't confuse lecture or circuit diagrams together with wiring diagrams; wiring diagrams will usually show images of components like the pictorial, and the way the whole or portion of a circuit is wired. The distinction is that wiring diagrams generally put an emphasis on real physical location of necessary components relative to each other that essentially tell a layman Just What to do about the wiring)
Here is a version of a schematic diagram called a ladder structure. The principal goal of this diagram is to demonstrate the logic (referring to electric management ) of a circuit board. This diagram is the one that I mostly come across in my line of work, and it's extremely successful for troubleshooting issues or learning how a circuit functions. Some frequencies are so huge that many types of schematic diagrams need to be read in increments from novel form (usually with coded numbers so that info can be simpler located ). Again, here is the identical precise circuit since the first two weeks, however, looking at it in ladder shape.
