Chifukwa chachikulu cholumikizira cha 380V AC chimayaka pamagetsi ndi chifukwa cha kusankha kolakwika kwa koyilo. Mphamvu ya koyilo ya AC contactor iyenera kufanana ndi mphamvu yamagetsi.

Kodi ma circuit breakers, load switch and disconnectors ndi chiyani? Mwinamwake ambiri ogwira ntchito zamagetsi ndi omveka bwino. Koma zikafika pa kusiyana ndi kugwiritsa ntchito pakati pa ophwanya dera, zosinthira katundu ndi zolumikizira, ambiri ogwira ntchito zamagetsi amatha kudziwa chimodzi koma osati chinacho, komanso kwa oyambitsa magetsi, sadziwa zomwe angafunse. Tonse tikudziwa kuti wowononga dera akhoza kutseka, kunyamula ndi kuswa zomwe zikuchitika pansi pa nthawi yanthawi zonse, ndipo akhoza kutseka, kunyamula ndi kuthyola zamakono pansi pazikhalidwe zachilendo (kuphatikizapo nthawi yochepa) mkati mwa nthawi yeniyeni. Kusinthana kwa katundu ndi chipangizo chosinthira pakati pa wowononga dera ndi chosinthira chodzipatula. Ili ndi chipangizo chozimitsa cha arc chosavuta, chomwe chimatha kudula kuchuluka kwa katundu wapano ndi kuchuluka kwanthawi yayitali, koma sikungathe kuletsa njira yachidule.

The AC contactor ndi wapakatikati ulamuliro chigawo chimodzi. Ubwino wake wagona pakutha kulumikiza pafupipafupi ndikudula mizere ndikuwongolera mafunde akulu okhala ndi zolowera zazing'ono. Kugwira ntchito molumikizana ndi cholumikizira chamafuta owonjezera kungaperekenso chitetezo chochulukirapo pazida zonyamula. The AC contactor ndi ambiri ankagwiritsa ntchito otsika-voteji kulamulira chipangizo mu ulamuliro basi ndi magetsi pagalimoto kachitidwe.

POINT I/O ndi banja lazinthu zamtundu wa I/O zomwe zili zoyenera kugwiritsa ntchito zomwe zimafunikira kusinthasintha komanso kutsika mtengo kwa umwini. Ndi ma module amodzi mpaka asanu ndi atatu a kachulukidwe ka tchanelo, kuphatikiza gawo lodzipangira lokha, kusinthasintha kwa POINT I/O kumachepetsa mtengo ndi kukula kwake. Kutha kusakaniza I/O yokhazikika komanso yotetezeka kumapereka kusinthasintha kwakukulu komanso mwayi wokhazikika, mosasamala kanthu za zomwe mukufuna.
