簡單介紹:
DRA-ACT-2I系列AC電流輸入,DRA-ACT-2V系列AC電壓輸入,±0.1%精度,高抗噪性,薄型外殼
詳情介紹:

DRA-ACT-2I和DRA-ACT-2V系列是隔離式2線回路供電交流電流和交流電壓輸入DIN導(dǎo)軌安裝式信號調(diào)節(jié)器,可將測得的輸入轉(zhuǎn)換為成比例的線性和高精度4-20 mA輸出電流。

DRA-ACT-2I系列交流電流輸入型號包括0 to 1 Aac和0 to 5 Aac輸入以及4 to 20 mA輸出的型號。

DRA-ACT-2V系列交流電壓輸入型號包括0 to 150 Vac、0 to 250 Vac和0 to 400 Vac輸入的型號,同樣具有4 to 20 mA輸出。


為了完全平安,內(nèi)部變壓器將信號調(diào)節(jié)器輸入與輸出隔離開來從而使這些裝置能夠承受較大的瞬時(shí)輸入。完整的輸入到輸出隔離,高浪涌電流容量和高輸出信噪比使這些信號調(diào)節(jié)器具有很高的性不受接地回路信號和RFI的影響。這些發(fā)射器還配備了一個(gè)“測試”端子它通過測量內(nèi)部10 歐姆電阻器,不會干擾4 to 20 mA過程回路。
