模擬標準信號
AD-STVEX 710 GVD
產品介紹
電源隔離放大器用于為安裝在危險區域的變送器提供本質安全電源。電源隔離放大器本身作為相關電氣設備安裝在非危險區域（即安全區域）。信號被電隔離并傳輸到非危險區域。無源輸入還允許來自危險區域的有源信號。有源電流輸出、電流吸收輸出和電壓輸出便于適應后續信號輸入。該設備可在 24 V DC 或 230 V AC 下運行。

接觸放大器
AD-KVEX 100/200 GVD
產品介紹
接觸放大器（開關放大器）優選地用于保護弱傳感器接觸或放大二進制傳感器信號。 AD-KVEX 100/200 GVD 提供在觸點輸出處放大的邏輯輸入信號。典型的輸入信號是簧片觸點、符合 Namur Namur (DIN EN 60947-5-6) 的信號傳感器或電阻變化。在輸出端，提供重載和無源觸點。對于每個導管，邏輯切換方向以及線路故障識別是可單獨切換的。 AD-KVEX 100/200 GVDO 版本具有無磨損半導體輸出，也通過光學隔離進行電流隔離。該器件包含電子寬范圍電源，可以在寬電源電壓范圍內運行。
