Hāʻawi ka mea hoʻokomo analog i ka pale palekana palekana me ka hana pale ʻana i ka piʻi ʻana i ka lako mana kaʻawale no ʻelua - a ʻekolu mau mea hoʻouna uea i nā wahi pōʻino. ʻO ka hōʻailona 4-20mA i hana ʻia e ka transmitter a i ʻole ke kumu o kēia manawa e lawe ʻia mai ka wahi pōʻino i kahi puka palekana, a laila e hoʻokau i ka ukana ma kahi palekana. No ʻelua - a ʻekolu paha mea hoʻouna kelepona a i ʻole nā hōʻailona kumu o kēia manawa, kākoʻo kēia pale palekana i ke kamaʻilio bidirectional o ka hōʻailona kikohoʻe Hart i hoʻopaʻa ʻia ma ka hōʻailona 4-20mA a loaʻa iā ia kahi hana hoʻokiʻekiʻe uea.
Pono kēia huahana i ka lako mana kūʻokoʻa, me nā mana hoʻokaʻawale, hoʻokomo, a me nā hopena puka.
