型號750-484/040-000模塊
2通道的模擬輸入; 4 ... 20 mA HART;本質(zhì)安全;極端

描述

模擬輸入模塊用于連接兩個(gè)基于現(xiàn)場的HART接口變送器，用于0 + 1區(qū)域的危險(xiǎn)區(qū)域。

它提供傳感器，通過模擬接口記錄過程值，并啟用HART通信以參數(shù)化或記錄次要變量。

WAGO-I / O-SYSTEM 750 XTR的安裝必須在2區(qū)或非爆炸區(qū)域進(jìn)行。

24 V的電源電壓通過串聯(lián)電阻從電源觸點(diǎn)饋送到現(xiàn)場連接（HART +）。屏蔽連接直接連接到DIN導(dǎo)軌。

測量輸入配有限流功能，可將電流限制在最大25 mA。該模塊為沒有自己電源的2線制變送器提供電源。

每個(gè)通道最多可將4個(gè)HART輔助變量（PV，SV，TV，QV）插入耦合器或控制器的循環(huán)過程映像（可配置）。對于連接到所連接的智能HART現(xiàn)場設(shè)備的HART通信，HART協(xié)議可以顯示在耦合器或控制器的循環(huán)過程映像中（可參數(shù)化）。

對于某些（可編程）耦合器，可以使用FDT / DTM設(shè)備驅(qū)動程序，以便HART工具路由到連接的HART設(shè)備。

該設(shè)備適用于惡劣的環(huán)境條件：

大大擴(kuò)展了溫度范圍
更高的介電強(qiáng)度和EMC電阻
更高的抗振動和抗沖擊性
