Using sinking inputs on a relay style of Schneider Modicon M221 PLC (Video 3 in a technical series)

If you have ever needed to wire a Schneider Modicon M221 PLC but not known where to begin, then this is the series you need. In this video series, we go through “How to Wire” each part of these programmable logic controllers in depth, referring to the manufacturer’s data sheets and industry best practices. Playlist videos are all listed below.

Most of these videos are exclusive to the M221 line. With the exception of Video 2 which is all about Sinking/Sourcing and IEC Positive/Negative logic. These are general concepts that, although taught on a Schneider PLC, could be applied to any PLC or smart relay out there, whether it is Schneider, ABB, Siemens, Allen-Bradley, Omron, Automation Direct, or any of the multitude of others available.

The remaining videos in this series will all be dealing with specific Schneider M221 PLC's, and will show you how to wire each of the inputs or outputs properly. Browse through the playlist, and watch the videos on the models that you are looking for help on.
