Activity 6-3 Control Systems Overview Objectives The term system is commonly defined as a combination of parts that work fi together to form a complete operating unit. In this respect, the term can apply to a variety of different systems used by industry to achieve some operation in the manufacturing process. An application of this term is the industrial electronic system. Further application of this term includes a wide variety of subsystems under the heading of industrial electronics. Opto-electronic systems, timing systems, digital systems, and environment control systems are all included in this study of industrial systems. Each industrial system includes a number of unique features or characteristics that distinguish it from other systems. More importantly, however, there are a number of basic functions common to all electronic systems. Energy source, trans- mission path, control, load, and indicator are terms commonly used to describe these basic system functions. In this activity, you will have an opportunity to study a representative system and pick out the basic parts of the system. By doing this, you will become more familiar with the systems concept and be able to apply it to a specific situation. fi Procedure 1. Briefl y define fl the function of the following basic system parts. Use general fi terms that would apply to all basic industrial electronic systems. • Energy source. • Transmission path. • Control. • Load. • Indicator. 2. Explain how the systems concept could be applied to an electrical power system used to supply an industrial plant site. 3. How could the systems concept be applied to a simple electrical circuit? + A SPST switch Ammeter Incandescent lamp Battery Goodheart-Willcox Publisher Electrical circuit.
