Solenoid control valve coil K23D-2 mea pneumatic

ʻO ka ʻokoʻa ma waena o AC coil a me DC coil

ʻElua ʻano o nā relay electromagnetic: AC a me DC. Ma ke kumu, ke hoʻohana ʻia ka volta DC i nā ʻaoʻao ʻelua o ka coil, ua hoʻoholo ʻia ke ʻano o kēia manawa e ke kūpaʻa o ka coil. No ka mea liʻiliʻi loa ka resistivity o ke keleawe, i mea e hōʻoia ai ʻaʻole nui ka nui o kēia manawa, pono e hana ʻia ka coil me ke anawaena uea lahilahi a me nā huli he nui. ʻO ka coil AC, ma ka ʻaoʻao ʻē aʻe, ua hoʻoholo ʻia kona manawa e ka reactance, no laila pono e hana ʻia ka coil me ke anawaena uea mānoanoa a me ka helu liʻiliʻi o nā huli. No laila, ke hoʻohana ʻia kahi relay 24V AC i kahi ʻōnaehana DC 24V, e puhi koke ka relay no ka mea ʻaʻole lawa ka nui o ke kū'ē. Eia nō naʻe, ke hoʻohana ʻia ka relay DC i ka ʻōnaehana AC, ʻaʻole hiki ke huki ʻia ka relay a ʻaʻole hiki ke huki i loko no ka nui o kona reactance.

1.Generally, he elua ano o ka relays: AC a me DC, a me ka AC mea nui 24VAC, 220VAC a me 380VAC. Pono e loaʻa i kēia mau kola wili relay AC he pou uhi, he mea maʻalahi ke hoʻokolokolo, akā ʻo ka hapa nui o nā relay AC liʻiliʻi ʻaʻole kēia pou uhi. Nui nā pae o ka volta DC, e like me 6, 12 a me 24 volts. He lahilahi ka wili relay a ʻaʻohe kia uhi o ke kumu.

Hiki i nā mea hoʻopili 2.AC ke pani i nā mea hoʻopili DC i ka wā o ka pilikia, aʻaʻole hiki i ka manawa huki keʻoi aku ma mua o 2 mau hola (no ka mea,ʻoi aku kaʻino o ka hoʻokuʻuʻana o ka wela o ka AC ma mua o ka DC, i hoʻoholoʻia e ko lākou mau hale likeʻole). ʻAʻole hiki ke hoʻololi ʻo DC i nā mea hoʻopili AC.

3.The coil huli o AC contactor he kakaikahi, oiai ka poe o DC contactor he nui, i hiki ke hoomaopopoia mai ka leo wili.
