PH1033信號(hào)隔離器、PH10333信號(hào)隔離器、PH103333無(wú)源信號(hào)隔離器
-
輸入輸出為直流電流信號(hào),可實(shí)現(xiàn)單路輸入輸出,雙路輸入輸出
□電路不設(shè)獨(dú)立的外供電源(簡(jiǎn)稱“無(wú)源”）
□電路由輸入端獲取電源能量,把輸入信號(hào)變送到輸出端
□輸出信號(hào)與輸入信號(hào)必須"一致",例輸入4～20mA,輸出亦為4～20mA
□當(dāng)?shù)?通道沒(méi)有輸入信號(hào)時(shí),相應(yīng)輸出端子空接沒(méi)有輸出信號(hào),見(jiàn)貨
號(hào)第7第8位定義,第7位缺省時(shí)，第8位亦缺省
□對(duì)測(cè)量輸入端電壓應(yīng)滿足≥隔離器在轉(zhuǎn)換過(guò)程中損耗電壓約
2.4～2.5V（以2.5V計(jì)）+輸出端負(fù)載電壓（例:負(fù)載電阻為250Ω×
電流為20mA=負(fù)載電壓5V,此時(shí)輸入電壓應(yīng)≥5V+2.5合計(jì)7.5V）
