The MTLx544 provides fully-floating dc supplies for energising two conventional 2-wire or 3-wire 4/20mA or HART transmitters located in a hazardous area, and repeats the current in other circuits to drive two safe-area loads. For smart transmitters, the unit allows bi-directional transmission of digital communication signals superimposed on the 4/20mA loop current. Alternatively, the MTLx544S acts as a current sink for a safe-area connection rather than driving a current into the load. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication. 上海卓峙自動化設(shè)備有限公司是一家從事工業(yè)自動化工程設(shè)計、安裝、調(diào)試、售后服務(wù)和代理銷售各類電氣，服務(wù)于一體的企業(yè)。公司堅持“信譽(yù)為本，誠信經(jīng)營”的理念，依靠網(wǎng)絡(luò)從事傳感器，安全柵、隔離柵，電源，低壓電器以及氣動液壓,儀器儀表,機(jī)電產(chǎn)品銷售與工程配套服務(wù)，公司為冶金、石油、化工、鋼鐵、電力、電子、船舶、汽車、環(huán)保、紡織、食品、醫(yī)療、制藥、包裝、等眾多行業(yè)提供完善的技術(shù)方案和備件服務(wù)。 特價銷售：德國倍加福(P F)，英國MTL安全柵，德國圖爾克(TURCK)，德國施克(SICK)，德國菲尼克斯(PHOENIX)，邦納(BANNER)，日本CKD，德國易福門(IFM)等，全系列安全柵，電源，模塊，傳感器，編碼器，端子繼電器等，公司備有大量庫存，另為客戶提供偏門冷門的歐州產(chǎn)品。
