>>>>>型号:DSDO120 模拟量输入（AI）回路调试工具
【功能描述】
DSDO120是ABB公司生产的模拟量输入（AI）回路调试工具，用于对ABB的模拟量输入（AI）回路进行调试和维护。
使用DSDO120工具时，需要仔细核对I0模块的地址分配，检查回路供电方式（内供电或外供电）是否与现场仪表相一致，用信号发生器在现场端对每个通道加入信号，通常取0、50%或100%三点进行检查。对有报警、联锁值的AI回路，还要在报警联锁值（如高报、低报和联锁点以及精度）进行检查，确认有关报警和联锁值是否正确

【英文介绍】
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
