罗斯蒙特手操器目前市场更为常用的是TREX手操器，今天我们要给大家介绍的是它的接口区别以及图和选择。

罗斯蒙特TREX手操器通讯模块有两个接口，可通过外部供电的HART回路或现场总线网段连接至HART和FOUNDATION现场总线设备，并与其通讯。Device Communicator通讯模块配有用于HART和FOUNDATION现场总线设备的特殊端子。罗斯蒙特TREX手操器多功能组态通讯模块可连接至HART和FOUNDATION现场总线设备,测量电流和电压，以及为设备供电。下面我们看看具体的对应接口功能：A.为FOUNDATION现场总线设备供电。您需要将FOUNDATION fieldbus电源插头连接到FF pwr和正FF端子。B.连接到外部供电或由Trex装置供电的FOUNDATION fieldbus设备。在4-20mA的电流回路上测量电流。D.通电并连接到HART设备。HART+pwr端子可测量所连接变送器的电流输出,或控制所连接定位器的电流输入。这些端子还配有用于设备通讯的回路电阻器。E.连接至外部供电的HART设备。HART端子也配有用于在4-20电流回路上进行HART通讯的可选回路电阻器以及用于移动定位器的可选电流控制装置。德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱: sales@whdkm.com原文出处：http://www.whdkm.net/html/537.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-pointer-lock allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&dt=1595839080850&bpp=5&bdt=581&idt=82&shv=r20200723&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=5191736091423&frm=23&ife=1&pv=2&ga_vid=1255610189.1595839081&ga_sid=1595839081&ga_hid=224729187&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=4&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1203&bih=586&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=1&eid=21066532&oid=3&pvsid=794859756608417&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.oxcmsnc6qgwg&fsb=1&dtd=125" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.oxcmsnc6qgwg" data-load-complete="true">
