The PGR-5330 is an advanced ground-fault and resistor monitoring relay that measures neutral current, neutral-to-ground voltage, and neutral resistance. The device also provides continuous monitoring ...

Even the best relays can fail at some point, but what causes them to fail? Conventional wisdom lays the blame on worn-out contacts. And there is some truth to that view. Every electromechanical relay ...

Vishay Intertechnology's VO14642AT 1 Form A solid-state relay offers fast switching speeds and low on resistance for a variety of industrial and test-and-measurement applications. Sept. 12, 2007 ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

Don�t heap all the blame for a wrong measurement on the DMM. There can be several less obvious sources of the errors. Testing assemblies and components usually includes checking the continuity of ...

Relays continue to be useful and popular, but in low-power, battery operated applications they tend to be power wasters. The following relay economy circuits reduce coil power significantly by simply ...
