In a wide range of applications, control components with different degrees of complexity are used. A simple control circuit is, for instance, a circuit that activates and disables a light. The control factor is always a single-pole turn in this circuit. Commercial and industrial control circuits have a more complex nature than this simple circuit and employ a wider range of components. Here are some basics about this stuff.
An example of a manual control is a simple on-off lighting control circuit. Manual control requires someone to turn on or off a switch. As in the previous example, the device on or off may be a light. In addition, a lot of other devices can still be controlled manually such as motorcycles.
While manual machine control remains common practice, many machines are automatically started and stopped or combined with manual and automated control. Automatic control takes place, when circuits can enable and disable something without interaction between people. We can find a lot of examples with automatic operation. It helps to operate without human monitoring it. For example, machines that were set with a timer as a washing machine.
Control circuits, a wide range of components are used. Components vary from warning lights to sophisticated devices that track, secure, and power AC engines. In certain situations, the relationship between these elements depends on the way they are wired. Sometimes this is called hard-wired logic. These components, such as a programmable logic control device or a variable speed drive are connected to a control panel. In these situations, both the cable and the software contained in the control unit are based on the operation of the circuit components.
That’s all for the basic brief about the control components. Feel free to share this knowledge and think that a small part in a machine can be helpful for it to run.
