TU921N冗余終端單元（也被稱為TU16R）是一款功能強(qiáng)大的設(shè)備：

一、產(chǎn)品概述

TU921N冗余終端單元是ABB公司生產(chǎn)的一款支持16個(gè)IO模塊的冗余終端單元。它支持冗余通信和電源，確保系統(tǒng)的高可靠性和穩(wěn)定性。該終端單元可以應(yīng)用于各種工業(yè)自動(dòng)化系統(tǒng)中，滿足不同的控制需求。

二、主要特點(diǎn)

冗余設(shè)計(jì)：TU921N冗余終端單元采用冗余通信和電源設(shè)計(jì)，確保在單個(gè)組件故障時(shí)，系統(tǒng)仍然能夠正常運(yùn)行。這種設(shè)計(jì)提高了系統(tǒng)的連續(xù)性和可靠性。

支持多個(gè)IO模塊：該終端單元最多可以支持16個(gè)IO模塊，能夠滿足復(fù)雜的工業(yè)自動(dòng)化控制需求。

易于維護(hù)：TU921N冗余終端單元具有集成的斷開機(jī)制，允許在運(yùn)行期間進(jìn)行更換，這意味著不需要中斷一次電壓以交換電源單元。此外，它還具有自動(dòng)診斷功能，可以簡化維護(hù)工作。

出色的配置和診斷：通過FDT/DTM進(jìn)行配置和診斷，使得用戶可以輕松地對終端單元進(jìn)行管理和維護(hù)。

堅(jiān)固耐用：該終端單元設(shè)計(jì)堅(jiān)固，適用于各種惡劣的工業(yè)環(huán)境。其涂層處理還可以防止腐蝕和損壞，延長使用壽命。

三、應(yīng)用領(lǐng)域

TU921N冗余終端單元可以廣泛應(yīng)用于各種工業(yè)自動(dòng)化領(lǐng)域，如制造業(yè)、石油化工、電力等行業(yè)。它可以作為控制系統(tǒng)的重要組成部分，實(shí)現(xiàn)對各種工業(yè)設(shè)備的遠(yuǎn)程監(jiān)控和控制。

四、技術(shù)參數(shù)
