Solid-state relay - Wikipedia
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay, but solid-state electronics contain no moving parts and have a longer operational lifetime.
Solid State Relay: Types of SSR Relays - Types & Operation
Solid state relay (SSR) is an electronic switching device made of semiconductors that switch (On and Off) a high voltage circuit using a low voltage at its control terminals. Unlike EMR (Electromagnetic relay) that has a coil and mechanical switch (physical contacts), the SSR relay uses Optocoupler to isolate the control circuit from the ...
