PLC Learning Series - What are PLC Inputs?

The programmable logic controller (PLC) is a simple rugged industrial computer. This free plc training series is designed for everyone to learn about these controllers. PLCs are constantly evolving and continue to be the best option for a variety of industrial automation applications. PLC inputs are one component of our PLC block diagram. The output actions of the PLC will be controlled based on the inputs. We will be looking at digital and analog inputs that can be wired to the programmable logic controller. We will be looking at wiring of a normally open (NO) push button, normally closed (NC) push button, 3 wire PNP sensor, and an analog sensor to the PLC. These will all be sinking inputs. Let’s get started. More information can be obtained at our website. This includes all of the links mentioned in this video. https://accautomation.ca/plc-learning-series-what-are-inputs/ Previously in this PLC Learning Series: PLC Training Series - Tutorial for Everyone https://accautomation.ca/plc-training-series-tutorial-for-everyone/ https://youtu.be/9TpW32gw2Kg 00:00 PLC Learning Series - What are Inputs? 02:05 Discrete vs Analog PLC Inputs 02:57 Discrete PLC Inputs 05:50 Hardware Testing Discrete PLC Inputs 08:02 What does Sinking and Sourcing mean? 09:06 What are NPN and PNP Sensors? 12:23 Wiring Analog PLC Input 13:43 Testing the Analog Input 14:26 PLC Input Logic Program PLC Beginner’s Guide to PLC Programming There are many different PLC manufacturers with different hardware and software. All of the programmable logic controllers have similar basic features. Here is how I would approach learning about basic PLCs. https://accautomation.ca/programming/plc-beginners-guide/ Once you are familiar with the basics of the PLC you would then learn specifics for the controller that you will be programming. This is the easiest way to learn about PLC programming. https://www.accautomation.ca/
