The MTL5314 connects to a 2- or 3-wire 4/20mA transmitter or current source located in the hazardous area. It supplies one or two configurable alarm signals to the safe area via changeover relays. Each relay may be configured individually to signal an alarm condition (relay de-energised) when the input signal is greater than or less than a pre-set value. In addition, the MTL5314 can be connected in series to the hazardous-area side of an MTL5541 4/20mA repeater power supply (or equivalent device) to provide two trip alarm outputs direct from the transmitter signal (see schematic diagram). Looping the transmitter signal through the MTL5314 (via terminals 1 and 3) does not affect HART ? communications. 上海卓峙自動化設備有限公司是一家從事工業自動化工程設計、安裝、調試、售后服務和代理銷售各類電氣，服務于一體的企業。公司堅持“信譽為本，誠信經營”的理念，依靠網絡從事傳感器，安全柵、隔離柵，電源，低壓電器以及氣動液壓,儀器儀表,機電產品銷售與工程配套服務，公司為冶金、石油、化工、鋼鐵、電力、電子、船舶、汽車、環保、紡織、食品、醫療、制藥、包裝、等眾多行業提供完善的技術方案和備件服務。 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品。
