PH1033信號隔離器、PH10333信號隔離器、PH103333無源信號隔離器
-
輸入輸出為直流電流信號,可實現(xiàn)單路輸入輸出,雙路輸入輸出
□電路不設(shè)獨立的外供電源(簡稱“無源”）
□電路由輸入端獲取電源能量,把輸入信號變送到輸出端
□輸出信號與輸入信號必須"一致",例輸入4～20mA,輸出亦為4～20mA
□當?shù)?通道沒有輸入信號時,相應(yīng)輸出端子空接沒有輸出信號,見貨
號第7第8位定義,第7位缺省時，第8位亦缺省
□對測量輸入端電壓應(yīng)滿足≥隔離器在轉(zhuǎn)換過程中損耗電壓約
2.4～2.5V（以2.5V計）+輸出端負載電壓（例:負載電阻為250Ω×
電流為20mA=負載電壓5V,此時輸入電壓應(yīng)≥5V+2.5合計7.5V）
