This course covers all aspects of the Input/Output system for PLCs including discrete, analog, and data I/O. In addition, the course also presents an overview of I/O addressing and an introduction to Allen-Bradley I/O parameters. Course topics also include the principles of remote I/O and an introduction to scaling and resolution of analog devices and signals.

Learning Outcomes:

Upon completion of this module the student will be able to:

  • Explain the purpose of the I/O system
  • Describe how I/O addressing is accomplished.
  • Define discrete inputs.
  • List four tasks performed by an input module.
  • Describe the basic operation of a discrete output.
  • Explain the purpose of data I/O interfaces.
  • Define analog I/O.
  • Describe the resolution of an analog I/O module.
