1746-OA161746-OA16在实际对模拟信号监控时出现下列问题:)模拟信号不稳定:工作电流数值:通过互感器取出的模拟电压信号经转换后的数字量跳动幅度在10---30;即在数字表上观察到的电流值在350,而经过A/D转换在PLC程序中观察到的数值在在340—370变化;)工作电压数值:通过互感器取出的模拟电压信号跳动幅度在200---300;即在数字表上观察到的电压值在450-459V,而经过A/D转换在PLC程序中观察到的数值在300---590之间变化,无法直接使用该数据进行比较判断;为此必须对采集的模拟信号进行处理,也就是进行平均值计算,平均值能够在很大程度上反映实际工作电源的有效值。常规的A/D模块是可以在模块上设定平均值的取样方式的。但DX140不具备该项功能,必须在PLC程序中处理:1746-OA16《销售态度》:质量保证、诚信服务、及时到位!《销售宗旨》:为客户创造价值是我们永远追求的目标!《服务说明》现货配送至***各地含税(17%)含运费!《产品质量》全新原装***!《产品优势》***销售薄利多销信誉好,口碑好,价格低,货期短,服务周到!Allen-Bradley(美国AB)1756-L61L62L631756-ENBT大量现货-----------------手机:18030229050电话:0592-5709821传真:0592-5709828***1878187406邮箱1878187406@***.comGEGeneralElectric3000AmpSpectraTapBox3P4WNEWGreatLakesGLIModel63PHORPControllerMod63MitsubishiMelsecAY51COutputModuleSync32PointNIBSquareDI-LineFJA34030Powerpact30Amp30AmpASquareDI-LineMA36600600AA600AmpW/ShuntTripSquareDI-LineFAB26070ABFAB-26070AB70Amp70AmpASquareDI-LineFH26020ACFH2602020Amp20AmpA20ASquareDI-LineCircuitBreakerKC34150150Amp150AmpSquareDI-LineCircuitBreakerFH3601515AmpA15AmpDragerPolytron4543405TXSensingHeadGasDetectorSewEurodriveMovidriveMDV60A0055-5A3-​4-008.7kVAWestinghouseBreakerHFB3010HFB301010AmpA10AAmpMitsubishiMelsecAX42InputModuleSink64PointNIBWestinghouseBreakerHFA3080MHFA301010AmpA10AAmpBus***annLPJ-350SPLow-PeakFuse350AmpAClassJBussGEGeneralElectric3000AmpSpectraEndTapBox3P4WSylvaniaTransformer51kVA460/460Y/266V3PH51kVAYAllenBradleyAB513BAB38GSize1BreakerComboStarterSiemens6SN1114-0NB01-0​AA1611UOption-ProfibusDP3NIBBeckActuator11-307-078354-0​1120V400lbTorqueGouldITE800AAmpR508ABGBuswayEndTapBox3P4WGEGeneralElectric600ABusswayExpansionUnit3P3WWestinghouseMoldedCaseSwitchMC3800WK800AmpA800ASquareDTypePAF2000Amp2000AAPAF2600001433SwitchProFaceGP570-TC31-24VDigitalGP570TC3124VGP70Series)
