Back in the 70s, industrial control was done with either relays and ladder logic or new programmable logic controllers. These devices turned switches on and off, moved stuff around a factory, and ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Relay logic is a way of expressing the logic of a control circuit using relays, switches, timers, and other devices. Relays are electromechanical devices that use an electric current to open or ...

Learn how to program a basic motor control circuit using ladder logic, a graphical programming language for industrial automation systems. Follow these steps to design, test, modify, and optimize ...

To operate the transmitter, and especially to accommodate the vacuum-tube amplifier, older transmitters use relay logic, more typically known in broadcast engineering as a control ladder. Essentially ...

An algorithm for converting relay ladder logic (RLL) programs for programmable logic controllers (PLCs) into sequential function chart (SFC) programs is introduced. Since an SFC (a standardization of ...
