1. Kenyelletso e khutšoane ea li-relay
A phetisoke ansesebelisoa sa ho laola motlakasee etsang phetoho e reriloeng esale pele ka bongata bo laoloang potolohong ea phallo ea motlakase ha palo ea ho kenya (excitation quantity) e fetoloa ho fihlela litlhoko tse boletsoeng.E na le kamano e kopanetsoeng pakeng tsa tsamaiso ea taolo (eo hape e bitsoang "input circuit) le tsamaiso e laoloang (eo hape e bitsoang output circuit).Hangata e sebelisoa ho li-circuits tsa ho laola ka mokhoa o itekanetseng, ha e le hantle ke "swichi e iketsang" e sebelisang motlakase o monyenyane ho laola ts'ebetso ea motlakase o moholo.Ka hona, e bapala karolo ea taolo ea othomathike, ts'ireletso ea polokeho le potoloho ea phetoho potolohong.
2. Karolo e ka sehloohong ea li-relay
Relay ke ntho e ikemetseng ea ho fetoha e nang le ts'ebetso ea ho itšehla thajana, ha phetoho ea ho tsosoa ha potoloho ea ho kenya e fihla boleng bo boletsoeng, e ka etsa hore potoloho ea matla a laoloang e fetohe phetoho e reriloeng esale pele ho sesebelisoa sa taolo ea potoloho ea othomathike.E na le mochine oa kutlo oa ho arabela ho tsosoa ha ka ntle (motlakase kapa o seng oa motlakase), actuator ho laola "ho" le "off" ea potoloho e laoloang, le mokhoa oa ho bapisa o mahareng ho bapisa, ho ahlola le ho fetola boholo ba thoholetso.Li-relay li sebelisoa haholo taolong ea remoutu, telemetry, puisano, taolo ea othomathiki, mechatronics le theknoloji ea sefofane ho laola, ho sireletsa, ho laola le ho fetisa tlhahisoleseling.
Ka kakaretso li-relay li na le mochine oa induction (karolo ea ho kenya) e bonts'ang mefuta e itseng ea ho kenya (joalo ka hona joale, voltage, matla, impedance, frequency, mocheso, khatello, lebelo, leseli, joalo-joalo);actuator (karolo ea sehlahisoa) e laolang potoloho e laoloang "ho" le "tima";le mochine o bohareng (karolo ea koloi) e kopanyang le ho arola palo ea ho kenya, ho sebetsana le ts'ebetso le ho khanna karolo ea tlhahiso pakeng tsa likarolo tse kenang le tse hlahisoang.Pakeng tsa likarolo tse kenang le tse hlahisoang tsa relay, ho na le mochine o bohareng (karolo ea koloi) e kopanyang le ho arola ho kenya letsoho, ho sebetsana le mosebetsi le ho khanna tlhahiso.
Joaloka karolo ea taolo, relay e na le likarolo tse 'maloa.
(1) Ho atolosa sebaka sa taolo: Ka mohlala, lets'oao la taolo ea li-relay tse ngata ho fihlela boleng bo itseng le ka fetoloa, la buloa le ho bulela lipotoloho tse ngata ka nako e le 'ngoe ho ea ka mefuta e fapaneng ea lihlopha tsa ho ikopanya.
(2) Amplification: Ka mohlala, li-relay tse hlokolosi, li-relays tse bohareng, joalo-joalo, ka taolo e nyenyane haholo, u ka laola potoloho e matla haholo.
(3) Matshwao a kopantsweng: Ka mohlala, ha matshwao a taolo a mangata a feptjwa ho relay e nang le mefuta e mengata ka mokgwa o behilweng, a bapiswa le ho kopanngwa ho fihlela sephetho se rerilweng esale pele.
(4) Automatic, remote control, monitoring: Ka mohlala, li-relay tsa lisebelisoa tsa othomathike, hammoho le lisebelisoa tse ling tsa motlakase, li ka etsa lithapo tsa taolo tse hlophisitsoeng, kahoo tsa nolofalletsa ts'ebetso ea othomathike.
