1753-IB8XOB81753-IB8XOB81753-IB8XOB8PLC控制取代继电器控制已是大势所趋，如果用PLC改造继电器控制系统，根据原有的继电器电路图来设计梯形图显然是一条捷径。这是由于原有的继电器控制系统经过长期的使用和考验，已经被证明能完成系统要求的控制功能，而继电器电路图又与梯形图有很多相似之处，因此可以将继电器电路图经过适当的“翻译”，从而设计出具有相同功能的PLC梯形图程序，所以将这种设计方法称为“移植设计法”或“翻译法”。在分析PLC控制系统的功能时，可以将PLC想象成一个继电器控制系统中的控制箱。PLC外部接线图描述的是这个控制箱的外部接线，PLC的梯形图程序是这个控制箱内部的“线路图”，PLC输入继电器和输出继电器是这个控制箱与外部联系的“中间继电器”，这样就可以用分析继电器电路图的方法来分析PLC控制系统。我们可以将输入继电器的触点想象成对应的外部输入设备的触点，将输出继电器的线圈想象成对应的外部输出设备的线圈。外部输出设备的线圈除了受PLC的控制外，可能还会受外部触点的控制。用上述的思想就可以将继电器电路图转换为功能相同的PLC外部接线图和梯形图。【***】【诚信】【创新】【合作】【共赢】厦门泰尼电气有限公司【产品质量】原装进口***【检测标准】按原厂标准【产品质保】1年【快递时间】24小时到【联系我们】＆业务经理：小黄＆洽谈电话：0592-6809319/18950191386＆商务***：2917675397＆传真（FAX)：0592-6890859（请注明，01006收）＆公司全称：厦门泰尼电气有限公司＆公司地址：厦门市海沧区海沧街道滨湖一里1号楼GasonicsAuraA2000LLLoadlockAsher-AlcatelADK70DryPump-Edwa***iF30KVacuumPump-TestedandOperationalShimadzuTMP-3403MCTurboPumpwithCablesShimadzuTMP-2203LMCTurboPumpwithCablesATMIEcosysCDO862AbatementSystemEdwa***iXL5000VacuumPump-BuschDS160A-KVacuumPump-Edwa***iH1800VacuumPump-Tested&OperationalEbaraA30WVacuumPump-RefurbishedEbaraA30W-NVacuumPump-RefurbishedEdwa***STP-H1301L1BTurboPump-ManufacturerRefurbishedPfeifferTPH2301PNTurboPump-TestOperationalRefurbishedEdwa***iQDP80/QM***0DryPumpLeyboldTurbovac410MCT-RefurbishedEbara40x20DryVacuumPump-RefurbishedPfeifferTMH1600PCTurboPump-SpinningRotorBuschWZ2000ABoosterPump-ATMIEcosysVectorUltra5000Scrubber-AlcatelATH1600MTurbo-CTICryogenics9600Compressor-RefurbishedRefurbishedEdwa***iQDP40/QMB250DryPumpRefurbishedEdwa***iQDP80DryPumpRefurbishedEdwa***iQDP40DryPumCTI8FTorrCryogenicsPump-RefurbishedCTI8FRetrofastCryogenicsPump-RefurbishedCTI8RetrofastCryogenicsPump-RefurbishedCTI8FCryogenicsPumpConflatFlange-RefurbishedCTI8FRetrofastCryogenicsPumpwithCFFlangeCTI8FTorrCryogenicsPump-RefurbishedLeyboldWAU2001Blower-OperationalEdwa***STP-H1301L1BTurboPumpControllerw/Cables-TestedEdwa***iL600VacuumPump-TestedBuschCobraDryVacPumpCS250-forPartsOsakaTG1133EMTurboPumpRotorSpinsFreelyLeyboldD65BCSVacuumPump-RefurbishedEdwa***iQDP80/QMB250VacuumPump-Tested&OperationalBuschCobraDryVacPumpCS100-forPartsPfeifferMVP015.4(PKT05066)Pump-OperationalEdwa***EH4200Blower-StokesStealthDryPumpComdelCX600RFPowerSupplyPoweredUpAlcatelRSV1002BoosterPump-SeikoSeikiSTPH1000LTurboCable&AlcatelRSV600BoosterPump-AlcatelRSV601BoosterPump-AlcatelRSV602BoosterPump-SeikoSeikiSTPH1301LIBTurboCable&Controller-LeyboldD25BCSVacuumPump-RefurbishedRefurbishedEdwa***iQDP80DryPump-Tested&OperationalAffinityF-SeriesChillerAlcatelACT1300M/1600MController-BuschWY1250BoosterPump-LeyboldWSU250BlowerBoosterPumpRebuilt&TestedEdwa***250WaterCooledTrapAlcatelADS501DryPump-BuschWY500BoosterPump-Edwa***L70DryVacuumPump-forPartsEbara305WTurboPumpController-forPartsNeslabHX-75DigitialChillerSinglePhaseM&WFlowriteRPCX17ChillerAMATZeroHeatExchangerBuschWY700BoosterPump-LeyboldWS151BoosterPump-Alcatel2033CP1w/LinesforExternalFilterAlcatelZT2030CVacuumPumpw/LinesforExternalFilterAlcatelM2033CVacuumPumpwithFilterNeslabESC-150ChillerEdwa***ToolInterfaceModuleA52844464OperationalTIMEdwa***ToolInterfaceModuleU20000521OperationalTIMEdwa***ToolInterfaceModuleA52844488OperationalTIMLeyboldS65BCSVacuumPump-ForPartsStokes212/412PistonSlidePN243595011Stokes212/412HollowEccentricPN278575001Stokes212/412SolidEccentricPN252459001AlcatelRSV300BoosterPump-VarianV60TurboPumpRotorSpinsFreelyLeyboldWS500BoosterPump-BuschWX-1000PandaBlower-forPartsSyconSTM-100/MFThinFilmDepositionThicknessRateMonitorKinneyKC-5KC5RotaryPistonVacuumPump-RebuiltMKSBaratronType626PressureTransducer-OperationalAlcatelRSV301BoosterPump-Varian2033CP1Multi-VacPumpController-forPartsAlcatel2060VacuumPump-forPartsMKSMFCRS4851179A13CG1***-OperationalGranvillePhillips275ConvectronGaugeandDisplayMFJDifferentialTTunerModel986-OperationalACMEPowerSupply-OperationalMFJ993-IntelliTunerAutomaticTuner-OperationalPneumaticBellowsSealedSSInlineValveKF40-SL0150PVQFSwagelokNuproValveSS-4BMG-VCR-OperationalISO100toISO100w/KF25port,6”VacuumAdapterISO100toISO100w/KF25port,5”VacuumAdapterISO100toISO63,2”VacuumAdapterISO100BtoISO63Bw/KF25port,2.5”VacuumAdapter)
