140CPU67160C處理器模塊,140CPU67160C使用指導
系統(tǒng)中可能安裝的16通道模擬電流輸入模塊的數(shù)量取決于可用的%AI和%I引用的數(shù)量。每個模塊使用1%到16%的人工智能參考（取決于啟用的通道數(shù)）和8%到40%的I（取決于報警狀態(tài)配置）參考。可用的%AI參考是：在311型、313型和323型系統(tǒng)中為64，128在331型系統(tǒng)中，在340和341型系統(tǒng)中為1024，在351和341型系統(tǒng)中為2048352型系統(tǒng)。
140CPU67160C處理器模塊可安裝在電源中的16通道模擬電流輸入模塊的最大數(shù)量系統(tǒng)包括：
4在311型、313型和323型系統(tǒng)中
8在331型系統(tǒng)中
12在340型和341型系統(tǒng)中
51在351型和352型系統(tǒng)中在規(guī)劃應(yīng)用程序的模塊配置時，還必須考慮負載安裝電源的容量和所有模塊的總負載要求安裝在底板中。有關(guān)詳細信息，請參閱90-30系列可編程控制器安裝手冊GFK-0356電源和模塊負載要求。通道1到16個可選數(shù)量；單端輸入電流范圍0至20 mA、4至20 mA和4至20 mA增強（每個通道可選）校準工廠校準至：在4至20 mA范圍內(nèi)，每次計數(shù)4μA在0至20 mA和4至20 mA增強范圍內(nèi)，每計數(shù)5μA更新速率13毫秒（全部16個通道）4-20 mA時的分辨率4μA（4μA/位）0-20 mA時的分辨率5μA（5μA/位）4-20 mA時的分辨率增強了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)
