SRWP-9057無(wú)源·配電器
儀表概述:
WP-9000系列無(wú)源·配電器(輸出環(huán)路供電),是向現(xiàn)場(chǎng)的二線制變送器提供隔離的電源電壓,并將變送器產(chǎn)生的 4~20mA 信號(hào)經(jīng)本配電器轉(zhuǎn)換成所需的直流信號(hào)至控制系統(tǒng)或其它智能儀表。主要用于具備輸入回路供電的DCS、PLC系統(tǒng)。
本配電器為回路供電方式,輸入回路-輸出回路之間*電磁隔離。
◆ 特性
● 將二線制變送器 4~20mA 信號(hào)輸入隔離轉(zhuǎn)換。
● 給變送器提供驅(qū)動(dòng)電壓(Uo=Ue-RL×I-Ud)。
● 信號(hào)傳送隔離輸出 4~20mA。
● 回路供電 12~30VDC 。
● 輸入回路短路保護(hù)。
● 即插即拔式接線端子,DIN導(dǎo)軌卡式安裝。
