Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

One advantage of solid-state relay (SSR) over conventional electro-magnetic relay (EMR) is its tear and wear free operation. S201S01 from Sharp is a good example. Here is the circuit diagram of a DIY ...

The electronic circuitry to drive one of these relays from logic signals can be a half-bridge if dual supply voltages are available or a full bridge—that is, an H-type power driver—if only a single ...
