DMS-20PC-7-DCM工業(yè)自動(dòng)化與控制的面板儀表規(guī)格書(shū)PDF中文資料

DMS-20PC-7-DCM屬于工業(yè)自動(dòng)化與控制的面板儀表。由村田制作所制造生產(chǎn)的DMS-20PC-7-DCM面板儀表面板儀表是使用模擬指針或其他物理指示器或數(shù)字字符以可視方式顯示輸入信號(hào)的儀器。許多面板儀表還包括可用于報(bào)警選項(xiàng)的輔助輸出，以及將數(shù)據(jù)或參考信號(hào)傳輸?shù)接?jì)算機(jī)或微控制器的功能。面板儀表可根據(jù)測(cè)量范圍、顯示類(lèi)型、字符/指示器屬性和供電電壓進(jìn)行選擇。儀表類(lèi)型包括電流、電壓、頻率、過(guò)程、電阻、溫度和功率。

DATEL’s new DMS-20PC-7-DCM self-powered digital voltage monitor is designed for monitoring –48V intermediate bus voltages in modern telecom/datacom/computer equipment. Its compact size and low power consumption (8mA typical) make it the ideal replacement for older, hardto-read, analog panel meters. Simply connect a –36 to –75Vdc input across the two rear terminals and the meter is fully operational!
