Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

HOPE – The University of Arkansas Hope-Texarkana will offer a Programmable Logic Controllers (PLC) Level 1 course on February 24–27, 2026, providing hands-on training for individuals seeking ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

In Part 1 of this two-part series, we explored PLC basics and voltage sag susceptibilities. In this segment, we present PLC voltage sag test results along with guidelines for making PLC systems more ...

This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...
