*1: Use two modules with the same suffix code foruse in dual-redundant configuration.
*2: When AAI543-□1□ is installed in a remote node, the ambienttemperature should be 0 to 60°C.
*3: The time during which the output to the fieldfalls below 4 mA at switch-over is 100 ms at maximum for AAI543-□0□(standard response) and 2 ms at maximum forAAI543-□1□ (fast response).When anyfast response field devices are connected to dual redundantly configuredmodules, AAI543-□1□ (fast response)should beused.
*4: The withstanding voltage for using thededicated cable is 500 V AC (between the input signal and the system).Thewithstanding voltage for using MIL connector cable depends on the electricalspecifications of its cable.
*5: When installing the module with HART functionto a remote node, the firmware of EB401 must be Rev 2 or later.For HARTfunction specifications, refer to “HART Communication Package (for A□I□□□-H) (GS 33Q03L70-31E).”
AAI543-S50模塊輸出4至20 mA。
分散控制系統(tǒng)：（DCS，即Distributed Control System），又叫集中分散控制系統(tǒng)，簡稱集散系統(tǒng)，也稱其為分布式控制系統(tǒng)，它是利用計算機(jī)技術(shù)、控制技術(shù)、通信技術(shù)、圖形顯示技術(shù)實現(xiàn)過程控制和過程管理的控制系統(tǒng)，它以多臺微機(jī)分散應(yīng)用于過程控制，通過通信總線、CRT顯示器，鍵盤、打印機(jī)等又能高度集中地操作、顯示和報警。
