倍加福KCD2-SCD-1信號隔離器

特征

?1通道信號隔離器

?24v直流電源(導軌供電)

?電流輸出650Ω負載

?HART I/P和閥門定位器

?精確度0.1%

?外殼寬度12.5毫米

?根據IEC 61508，安全等級可達最多SIL

應用

   這種信號調節器驅動智能I/P轉換器，電動閥門和定位器，并提供隔離non-intrinsically安全應用程序。的模擬值上疊加數字信號現場或控制端，雙向傳輸。電流通過DC/DC轉換器被重復終端1和2。一個開路電路對所述控制端允許通過控制進行斷鉛監測系統。

    如果數字通信的環路電阻太低，一個內部之間的250Ω電阻終端6和8可用，可用作HART通信電阻。用于連接HART通信器的套接字為集成到設備的終端。
