EIMT 151: Industrial Motor Controls

Credits 3 Class Hours2 lecture and 2 lecture/lab

This is an introduction to motor controls and the logic sequence that they implement. The course covers how to read a ladder diagram, including component recognition, use, and application. Students will develop skills to create a computer generated control diagram from a sequence of operations and learn troubleshooting skills to diagnose basic control functions.
