Kubuka konkhe
Le analog input leyehlukile umgodzi wekuphepha iniketa emandla leyehlukile emabili - kanye netintsatfu tekudlulisela tintsambo etindzaweni letiyingoti. Le 4 ~ 20mA signal leyakhiwa ngumdluliseli noma umtfombo wamanje idluliselwa kusuka endzaweni leyingoti kuya endzaweni lephephile lokukhiphako, ngaleyo ndlela kushayela umtfwalo endzaweni lephephile. Kubabili - noma labatsatfu labadlulisela tintsambo noma timphawu temtfombo wamanje, lesivimbelo sekuphepha sisekela kukhulumisana lokubili kwesiginali yedijithali yeHart lefakwe ngetulu kwesiginali ye-4 ~ 20mA futsi inemsebenti we-alamu yekuphuka kwetintambo. Lomkhicito udzinga kuphakelwa kwemandla lokutimele, ngekuphakelwa kwemandla lokuhlukanisiwe, kufaka, kanye netiphetho tekukhipha.
