140CPU67160C处理器模块,140CPU67160C使用指导
系统中可能安装的16通道模拟电流输入模块的数量取决于可用的%AI和%I引用的数量。每个模块使用1%到16%的人工智能参考（取决于启用的通道数）和8%到40%的I（取决于报警状态配置）参考。可用的%AI参考是：在311型、313型和323型系统中为64，128在331型系统中，在340和341型系统中为1024，在351和341型系统中为2048352型系统。
140CPU67160C处理器模块可安装在电源中的16通道模拟电流输入模块的最大数量系统包括：
4在311型、313型和323型系统中
8在331型系统中
12在340型和341型系统中
51在351型和352型系统中在规划应用程序的模块配置时，还必须考虑负载安装电源的容量和所有模块的总负载要求安装在底板中。有关详细信息，请参阅90-30系列可编程控制器安装手册GFK-0356电源和模块负载要求。通道1到16个可选数量；单端输入电流范围0至20 mA、4至20 mA和4至20 mA增强（每个通道可选）校准工厂校准至：在4至20 mA范围内，每次计数4µA在0至20 mA和4至20 mA增强范围内，每计数5µA更新速率13毫秒（全部16个通道）4-20 mA时的分辨率4µA（4µA/位）0-20 mA时的分辨率5µA（5µA/位）4-20 mA时的分辨率增强了5µA（5µA/位）
The number of 16-Channel Analog Current Input modules which may be installed in a system
depends on the amount of %AI and %I references available. Each module uses 1 to 16 %AI
references (depending on the number of channels enabled) and from 8 to 40 %I (depending on
alarm status configuration) references.
The available %AI references are: 64 in a Model 311, Model 313, and Model 323 system, 128
in a Model 331 system, 1024 in a Model 340 and 341 system, and 2048 in a Model 351 and
Model 352 system.
The maximum number of 16-Channel Analog Current Input modules which may be installed in a
system are:
4 in a Model 311, Model 313, and Model 323 system
8 in a Model 331 system
12 in a Model 340 and Model 341 system
51 in a Model 351 and Model 352 system
When planning the module configuration for your application you must also consider the load
capacity of the installed power supply and the total load requirements of all modules that are
installed in the baseplate.
Refer to the Series 90-30 Programmable Controller Installation Manual, GFK-0356 for details on
power supplies and module load requirements.Number of Channels 1 to 16 selectable; single ended
Input Current Ranges 0 to 20 mA, 4 to 20 mA and 4 to 20 mA Enhanced (selectable per channel)
Calibration Factory calibrated to:
4 µA per count on 4 to 20 mA range
5 µA per count on 0 to 20 mA and 4 to 20 mA Enhanced range
Update Rate 13 msec (all 16 channels)
Resolution at 4-20 mA 4 µA (4 µA/bit)
Resolution at 0-20 mA 5 µA (5 µA/bit)
Resolution at 4-20 mA Enhanced 5 µA (5 µA/bit)
