NHR-5200系列雙回路數(shù)字顯示控制儀
概述
NHR5200系列雙回路數(shù)字顯示控制儀針對(duì)現(xiàn)場(chǎng)溫度、壓力、液位、速度等各種信號(hào)進(jìn)行采集、顯示、控制、遠(yuǎn)傳、通訊、打印等處理，構(gòu)成數(shù)字采集系統(tǒng)及控制系統(tǒng)，廣泛運(yùn)用于電力、石化、冶金、輕工、制藥、航空等諸多領(lǐng)域。
雙路輸入，雙屏LED數(shù)碼顯示，且?guī)в泄庵M指示功能(0～100％)。
儀表可選擇數(shù)學(xué)運(yùn)算功能，有加(減)、乘、除三種運(yùn)算模型。
具備36種信號(hào)輸入功能，可任意選擇輸入信號(hào)類型；0.2％級(jí)測(cè)量精度。
熱電阻\熱電偶信號(hào)分辨率可切換：1℃或0.1℃。
具備“上下限報(bào)警”、“延時(shí)報(bào)警”、“斷線報(bào)警”、“閃爍報(bào)警”等報(bào)警功能，帶LED報(bào)警燈指示。
具有電壓、電流變送輸出信號(hào)可選。
支持RS485、RS232串行接口，采用標(biāo)準(zhǔn)MODBUS RTU通訊協(xié)議。
儀表可帶RS232C打印功能，具有手動(dòng)打印、定時(shí)打印、報(bào)警打印等功能。
帶DC24V饋電輸出，為現(xiàn)場(chǎng)變送器配電。
輸入、輸出、電源、通訊相互之間采用光電隔離技術(shù)。
