PHASE 1 FUNDAMENTALS

I/O Fundamentals

Inputs and outputs are how a PLC senses and controls the real world. Learn digital and analog I/O, the field devices behind them, and how everything wires to the PLC.

WHAT YOU'LL BE ABLE TO DO

How a PLC senses and controls the real world

Digital vs analog

Know the difference between discrete on/off signals and continuous analog values, with real examples of each.

Know the input devices

Understand proximity sensors, photoelectric sensors, and limit switches what they do and when each is used.

Outputs & actuators

See how the PLC actually controls a machine and the output devices and actuators that move it.

Wire field to PLC

Understand how a real field device connects to a PLC input the link between the physical world and your logic.

Read an I/O list

Build the mental model that makes I/O lists and wiring diagrams make sense.

Get ready to program

Walk in with the I/O foundation you need before you write a line of logic.

EVERYTHING INCLUDED

More than videos it's a toolkit you keep

  • Step-by-step video lessons: clear, focused, and built in the right order.
  • Downloadable reference sheets: keep the key facts at your fingertips on the job.
  • Knowledge checks: confirm each concept stuck before you move on.
  • Lifetime access & updates: including new lessons as the course grows.
WHO IT'S FOR

Built for the people breaking into automation

The Beginner

You're learning automation from scratch and want a clear path instead of scattered videos. Every lesson is built to take you from zero to genuinely capable, no prior experience assumed.

Career Transition

You already work in a plant and want to move into a dedicated controls role. This fills the exact gaps that get maintenance techs, operators, and electricians promoted into automation.

Frequently asked questions

Do I need to finish Electrical Basics first?

It's recommended I/O builds on the electrical foundation but if you already know the basics you can jump in here.

Will I learn real sensors?

Yes. We cover the proximity, photoelectric, and limit switches you'll actually see on equipment, not just abstract theory.

How does this connect to programming?

I/O is what your program reads and writes. Nailing this makes Phase 2 programming click much faster.

What's included besides videos?

An input-device quick reference and an I/O summary PDF, plus knowledge checks.
