DS200GSIAG1ABA通訊模塊實驗數(shù)據(jù)工控DCS系統(tǒng)自動化設備

描述469可監(jiān)測多達12個RTD輸入，用于定子、軸承、環(huán)境或其他溫度監(jiān)測。每個RTD的類型可現(xiàn)場編程為100? 鉑（DIN 43760），100? 鎳，120? 鎳或10? 銅RTD為三線式。每兩個RTD共享一個共同的回報。469 RTD電路補償導線電阻，前提是三根導線的長度相同。引線電阻不應超過25? 鉑/鎳型RTD或3? 銅型RTD的每根引線。應使用屏蔽電纜，以防止工業(yè)環(huán)境中的噪聲拾取。RTD電纜應靠近接地金屬外殼，遠離高電磁或無線電干擾區(qū)域。RTD引線不應與大電流載電線相鄰或在同一導管中。

                         產(chǎn)品英文詳情資料：

DESCRIPTION The 469 monitors up to 12 RTD inputs for Stator, Bearing, Ambient, or Other temperature monitoring. The type of each RTD is field programmable as 100 ? Platinum (DIN 43760), 100 ? Nickel, 120 ? Nickel, or 10 ? Copper. RTDs must be three wire type. Every two RTDs shares a common return. The 469 RTD circuitry compensates for lead resistance, provided that each of the three leads is the same length. Lead resistance should not exceed 25 ? per lead for platinum/nickel type RTDs or 3 ? per lead for copper type RTDs. Shielded cable should be used to prevent noise pickup in the industrial environment. RTD cables should be kept close to grounded metal casings and away from areas of high electromagnetic or radio interference. RTD leads should not be run adjacent to or in the same conduit as high current carrying wires.
