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 ...

What’s one to do with some nice little relays of questionable pinout, and prototyping board? How about a quietly clicky 4-bit counter using relay logic with tons of buttons? The register with LEDs and ...

Relay Output Programmable Logic Controllers (PLCs) are devices used in industrial control systems to manage and automate processes. They are designed to receive inputs, process them according to a ...
