:???098-DSD-HV050X羅克韋爾伺服驅(qū)動(dòng)器價(jià)格三線制變送器如圖三所示,所謂三線制即是電源正端用一根線,信號(hào)輸出正端用一根線,電源負(fù)端和信號(hào)負(fù)端共用一根線。其供電大多為24V.DC,輸出信號(hào)有4-20mA.DC,負(fù)載電阻為250Ω或許0-10mA.DC,負(fù)載電阻為0-1.5KΩ;有的還有mA和mV信號(hào),但負(fù)載電阻或輸入電阻,因輸出電路方式不一樣而數(shù)值有所不一樣。以上三個(gè)圖中,輸入接納外表的是電流信號(hào),如將電阻RL并聯(lián)接入時(shí),則接納的即是電壓信號(hào)了。
