DRC-4710 and DRC-4720:DIN導(dǎo)軌安裝式電橋輸入信號調(diào)節(jié)器
drc-4710
DIN導(dǎo)軌安裝
橋的輸入（稱重傳感器，應(yīng)變計）或電壓輸入
0至10伏直流電（drc-4710）或4到20毫安（drc-4720）輸出
經(jīng)濟(jì)
DIN導(dǎo)軌安裝的drc-4710和drc-4720信號調(diào)節(jié)器是獨立的直流電源模塊設(shè)計為橋式輸入（稱重傳感器，應(yīng)變計）或電壓輸入（不連接的橋梁，勵磁電源不使用）。這些信號調(diào)節(jié)器包含一個精密儀表放大器，濾波輸出和內(nèi)置的10V激發(fā)供應(yīng)可驅(qū)動350Ω橋
0到30 mV輸入范圍使drc-4710和drc-4720兼容大多數(shù)應(yīng)變稱重傳感器或壓力傳感器的輸出。兩種型號可供選擇，其中0至10伏直流輸出（drc-4710），和其他的4至20 mA輸出（drc-4720）。連接是通過方便的螺絲端子。零點和量程調(diào)整電位器位于外部，以便于檢修。
