Course Rationale:

The purpose of this course is to prepare students as technicians who will aspire to enter the electronics industry. Technicians are required to have a working knowledge of high power circuitry, robotics, electrical loads, electrical control devices, control systems, PLCs, motors and logic. This course teaches those skills through a series of lectures, labs, class discussions and student activities.

Course Objectives/Outcomes:

Develop existing electromechanical systems to meet specific performance criteria; troubleshoot electromechanical systems; and compile documentation to meet industrial standards.

Learning Outcomes:

• Describe the basic concepts of electrical safety.
• List the basic parts of a 3-phase motor control circuit
• Outline the basic components of relays and contactors.
• Identify industrial schematic symbols.
• Program PLC Ladder Logic programs and test on simulator.
• Describe various types of industrial sensors and summarize their operation.
• Describe the basic parts of DC and AC electric motors and explain how they operate.
