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 ...

I would like to turn on my car's heated seats over a mobile/cellular network using my iPhone, and I'm trying to figure out the simplest path. I know very little beyond that goal, but I know that RF, ...

The project has been constructed for applications that require automatic temperature control while providing highly accurate thermal control circuit. The LM35 temperature sensor is the heart of the ...

GOOSE Messaging (Generic Object-Oriented Substation Events) is the most used aspect of 61850. Replace copper wires with digital one, turn that Lock Out Relay (LOR) into a latch bit in a relay and send ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

This circuit is a relay driver that is based on a PIC16F84A microcontroller. The board includes four relays so this lets us to control four distinct electrical devices. The controlled device may be a ...
