Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

Overcurrent relays with inverse definite minimum time (IDMT) characteristics are widely used in power systems to protect ...

One of my favorite activities is discovering the inner secrets of electronics systems as I am always looking for interesting design ideas. That way, I can take those design tricks a step further, ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

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 ...

The T-type circuit structure consists of three MOS FET relays that help reduce the leakage current to a minimal level without affecting the test equipment's inspection accuracy, allowing ...
