Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

This file type includes high resolution graphics and schematics when applicable. According to the research firm IHS Inc., about 54 million relays and timers were purchased in 2013, a number projected ...

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 ...

This 12V solar charge regulator meets most small-scale application requirements. With a current rating of 6A, it can handle up to a 100W solar panel. Its principle of operation is very simple and ...
