https://en.wikipedia.org/wiki/RelayA relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays

Numerical relay - Wikipedia
https://en.wikipedia.org/wiki/Numerical_relayThe digital protective relay is a protective relay that uses a microprocessor to analyze power system voltages, currents or other process quantities for the purpose of detection of faults in an electric power system or industrial process system. A digital protective relay may also be called a "numeric protective relay". It is also called numerical relay.

Releu (componentă electronică) - Wikipedia
https://ro.wikipedia.org/wiki/Releu_(componentă_electronică)Releul este o componentă electronică, un dispozitiv, care produce anumite modificări (cum ar fi închiderea și deschiderea unui circuit) pe baza unui parametru care variază (precum tensiunea electrică aplicată), permițând controlarea unui curent de intensitate mare cu ajutorul unui curent de intensitate mică.. Parametri principali. valoarea nominală (Un, In) este valoarea care ...
