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 ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Here’s an interesting introduction to Reed Relays, Mercury Displacement Relays, Contactors, Polar Relays, Latching Relays, T-Bar Relays, Time Delay Relays, and Stepping Relays. Here’s an interesting ...

Reed relays have evolved from their audio roots to handle GHz signals; MEMS technology may push them aside. This section ...

You can choose from a wide range of relays but do you know what type to use in your project? Well, sometimes is hard to choose, especially if you’re not sure which model you need or how a specific one ...

Relay testing goes beyond theory—real-world challenges demand adaptability, precision, and experience. Join us to explore ...

Protective relays are critical power systems components, and it is essential to design and use them properly to detect power system issues. As NETA-certified technicians, we must be familiar with the ...

Many single-phase motors used with refrigeration-duty, semi-hermetic and hermetic compressors require an external relay to assist in starting. How much do you know about these necessary products? An ...

The cost of component failures continues to increase as electronic products become more complex. Most component replacement costs are associated with marginal devices that become intermittent or fail ...

In 2006, INL validated the physics of Aurora when it succeeded in damaging a small ac motor by reclosing the motor ...
