Understanding Microprocessor Relay Logic – Relay Digital Logic Schemes

We have uploaded our third YouTube video, Understanding Microprocessor Relay Logic – Relay Digital Logic Schemes. (http://youtu.be/do3EkEcb0eM) This video discusses the different relay digital logic schemes that are available from the most commonly used manufacturers.

This video series is a re-creation of the first paper I ever presented from the NETA conference in 2001 that was the foundation of The Relay Testing Handbook series.

The video describes the most basic relay digital logic schemes, including:

• Individual Element (General Electric SR relay series or Beckwith Electric Co. relays)
• Binary Control Schemes (Alstom or Siemens relays)
• Matrix schemes (GEC Alsthom relays and Beckwith Electric relay element summaries)
• Arithmetic or Math Schemes (Schweitzer Engineering Laboratories)
• Logic Gates (General Electric UR series relays)

We’ve learned a lot about the YouTube format while creating this series and, unfortunately, it turns out converting PowerPoint to video is a little dry. Future video series will be much better.

We hope you found this video informative and hope you’ll stick with us as we get better with each series.
