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 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 ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

Rich was the editorial lead for CNET's Home and Wellness sections, based in Louisville, Kentucky. Before moving to Louisville in 2013, Rich ran CNET's desktop computer review section for 10 years in ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Reducing control panel lifecycle costs without sacrificing quality requires a panel-centric MRO strategy built on reliable, ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
