Description Of DC SSR Relay
How do solid state relays work?
the key characteristic of a solid state relay is that it requires no moving parts to perform the task of opening or closing contacts on a circuit.
Unlike a mechanical relay, there’s no positional change of any component within the solid state relay when it switches between on/off, open/closed states. Instead, a solid state relay works by converting the incoming electrical control signal to an optical one, often output via an infrared LED or similar (note, however, that the term ‘solid state relay’ is a generic one, and covers a variety of configurations).
This optical signal is then fired across a small gap of (permanently) open space within the module - known as an opto-isolator - to where it’s received by a photosensitive transistor, which in turn converts and sends on the signal to further electrical components. This completes the circuit and ultimately triggers the desired action, all without any contacts in the solid state relay ever coming into direct physical contact with one another.
