SIEMENS室溫傳感器QAA20系列產(chǎn)品介紹
這些裝置設(shè)計用于壁掛式安裝。 它們適用于大多數(shù)市售嵌入式接線盒。 電纜可以從后面（隱藏布線）或從下方或上方（表面布線）通過敲落開口引入。
該裝置由兩個主要部分組成：外殼和底板。 兩者咬合在一起，但可以再次分離。
測量電路、傳感元件和設(shè)定元件位于殼體內(nèi)的印刷電路板上。
底板帶有連接端子。
? 用于獲取室溫的主動傳感器
? 工作電壓 AC 24 V 或 DC 13.5…35 V
? 信號輸出 DC 0...10 V 或 4...20 mA
The units have been designed for wall mounting. They are suitable for use with most commercially available recessed conduit boxes. The cables can be introduced from the rear (concealed wiring) or from below or above (surface-run wires) through knock-out openings.
The units consist of two major sections: Casing and baseplate. Both snap together but can be detached again.
The measuring circuit, the sensing element and the setting element are located on the printed circuit board inside the casing.
The baseplate carries the connecting terminals.
? Active sensors for acquiring the room temperature
? Operating voltage AC 24 V or DC 13.5…35 V
? Signal output DC 0...10 V or 4...20 mA
