Unlike an electromechanical relay, there’s no positional change of any component within the solid-state relay when it switches between off/on (open/closed) states. Below you can see the basic block ...

Potential relays are sometimes referred to as voltage relays because they rely on the back-electromotive-force (BEMF) or voltage, which is generated by the motor for their operation. Even though some ...

Few realize how close an optical coupler resembles a relay. It is so close, in fact, that one can be wired as a Run-Stop latch circuit. One advantage over the relay is that it may be turned off via a ...
