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, ...

Relays can be designed for coil currents as low as 10 or 20 mA or as high as tens of amps, with contacts rated to handle just ...

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 ...

Found in a multitude of devices, relays are simple electromechanical switches featuring an electromagnet, one or more electrical contacts, a movable iron armature that is attracted by the magnetic ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

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

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 ...

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 ...
