Electronic Process Control

by David Charbonneau

Course Description

This is a complete program that features the Control Loop . The Control Loop is at the heart of a wide variety of electronic technology involving process control systems. Control systems are used in industrial and consumer products, from assembly lines to Video Cassette Recorders. Although the focus of the course is the Control Loop, students will learn all the fundamentals of Electronics. The Control Loop is implemented in a variety of circuits: Analog, Digital and Microprocessor. Unit 1 is an introduction to the principles and devices that make up a majority of all electronic circuits.

Electronics Process Control is a program offered through extension services at UCC. Each of the four units of the program are briefly descibed below. The course is offered evenings and Saturday mornings. It takes approximately one month to complete one level of a Unit; there are 3 levels in each Unit.

The course is designed to provide both a theoretical and a practical education. The theory time is approximately one-third and lab time is two-thirds. You are given a textbook and min-lab trainer to use while you are taking the course. A kit of electronics parts is yours to keep.

UNIT 1 Basic Electronics

Unit one is for the beginner in electronics. You will learn all the fundamentals of circuitry and circuit assembly. The practical portion of the course also teachs troubleshooting and measurement techniques.

UNIT 2 Analog Electronics

In unit two, you will learn how amplifiers work. This unit also includes how input and output sensors are connected to amplifiers and contol circuits.

UNIT 3 Digital Electronics

The subject of Unit three is the fundamentals of digital circuitry: digital logic, gates, displays and memory.

UNIT 4 Microprocessors

The fourth unit is a special application of Digital Electronics. In it you will learn how to program in Machine Language - the native language of Micropressors, and how to interface inputs and outputs to control systems.
