寶德8625-2型一體式溫度控制器@德國BURKERT控制器
德國Burkert 8625-2型一體式溫度控制器模塊是中科院方舟公司采用意法半導(dǎo)體(ST)ASIC芯片為實(shí)現(xiàn)無源交流隔離傳感器(互感原理)的兩線制電流遙測技術(shù)手段而定型生產(chǎn)的單片模塊產(chǎn)品。無源交流隔離傳感器(互感原理)輸入的電流電壓信號(hào)經(jīng)整流濾波和I/V轉(zhuǎn)換后輸出一個(gè)隨I1線性變化的直流電壓信號(hào)U2,U2作為浮地控制信號(hào)去控制該模塊輸出4~20mA的標(biāo)準(zhǔn)化電流環(huán)路,該模塊實(shí)現(xiàn)了無源交流隔離傳感器信號(hào)變換為兩根連接線路發(fā)送的呈線性比例的環(huán)路電流,接受器通過測量已知電阻RL兩端的壓降對(duì)環(huán)路電流進(jìn)行檢測。
德國Burkert 8625-2型一體式溫度控制器可以直接將被測主回路交流電流轉(zhuǎn)換成按線性比例輸出的DC4~20mA(通過250Ω 電阻轉(zhuǎn)換DC電量變送器1~5V或通過500Ω電阻 轉(zhuǎn)換DC2~10V)恒流環(huán)標(biāo)準(zhǔn)信號(hào),連續(xù)輸送到接收裝置(計(jì)算機(jī)或顯示儀表)。
德國Burkert 8625-2型一體式溫度控制器原副邊高度絕緣隔離,兩線制輸出接線,輔助工作電源+24V與輸出信號(hào)線DC4~20mA共用,具有精度高,體積小、功耗小、頻響寬、抗干擾、國內(nèi)*4種補(bǔ)償措施和6大全面保護(hù)功能,兩線端口防感應(yīng)雷能力強(qiáng),具有雷擊波和突波的保護(hù)能力等優(yōu)點(diǎn)。特別適用發(fā)電機(jī)、電動(dòng)機(jī)、智能低壓配電柜、空調(diào)、風(fēng)機(jī)、路燈等負(fù)載電流的智能監(jiān)控系統(tǒng)。
