ELCT 240 Introduction to Programmable Logic Controllers (PLC)4 credits
This course prepares students with the fundamentals of a programmable logic controller (PLC) and offers practical information and skills about programming techniques, control wiring, the theory of operation, and troubleshooting PLC systems. Using hands-on programming with a computer, students will design, create, modify, and test functional programs for different industrial applications. Allen-Bradley PLC-5 family programmable controller I/O modules will also be covered.
Prerequisites: ELCT 130 , ELCT 131 , and ELCT 132
Corequisites: ELCT 241
