>>>>>型號:DSDO120 模擬量輸入（AI）回路調(diào)試工具
【功能描述】
DSDO120是ABB公司生產(chǎn)的模擬量輸入（AI）回路調(diào)試工具，用于對ABB的模擬量輸入（AI）回路進(jìn)行調(diào)試和維護(hù)。
使用DSDO120工具時，需要仔細(xì)核對I0模塊的地址分配，檢查回路供電方式（內(nèi)供電或外供電）是否與現(xiàn)場儀表相一致，用信號發(fā)生器在現(xiàn)場端對每個通道加入信號，通常取0、50%或100%三點(diǎn)進(jìn)行檢查。對有報警、聯(lián)鎖值的AI回路，還要在報警聯(lián)鎖值（如高報、低報和聯(lián)鎖點(diǎn)以及精度）進(jìn)行檢查，確認(rèn)有關(guān)報警和聯(lián)鎖值是否正確

【英文介紹】
The DSDO120 is an analog input (AI) loop debugging tool produced by ABB for debugging and maintaining ABB analog input (AI) loops.
When using the DSDO120 tool, it is necessary to carefully check the address assignment of the I0 module, check whether the loop power supply mode (internal power supply or external power supply) is consistent with the field instrument, and use the signal generator to add signals to each channel at the field end, usually take 0, 50% or 100% three points for inspection. For the AI circuit with alarm and interlock values, it is also necessary to check the alarm interlock values (such as high, low and interlock points and accuracy) to confirm whether the relevant alarm and interlock values are correct
