IC754VGF08CTD输入模块;IC754VGF08CTD输入模块;IC754VGF08CTD输入模块(1)来自空间的辐***扰空间的辐射电磁场（EMI）主要是由电力网络、电气设备的暂态过程、雷电、无线电广播、电视、雷达、高频感应加热设备等产生的，通常称为辐***扰，其分布极为复杂。若PLC系统置于所射频场内，就回收到辐***扰，其影响主要通过两条路径；一是直接对PLC内部的辐射，由电路感应产生干扰；而是对PLC通信内网络的辐射，由通信线路的感应引入干扰。辐***扰与现场设备布置及设备所产生的电磁场大小，特别是频率有关，一般通过设置电缆和PLC局部及高压泄放元件进行保护。(2)来自系统外引线的干扰主要通过电源和信号线引入，通常称为传导干扰。这种干扰在我国工业现场较严重。(3)来自电源的干扰实践证明，因电源引入的干扰造成PLC控制系统故障的情况很多，笔者在某工程调试中遇到过，后更换隔离性能更高的PLC电源，问题才得到解决。PLC系统的正常供电电源均由电网供电。由于电网覆盖范围广，将受到所有空间电磁干扰而在线路上感应电压和电路。尤其是电网内部的变化，入开关操作浪涌、大型电力设备起停、交直流转动装置引起的谐波、电网短路暂态冲击等，都通过输电线路到电源边。PLC电源通常采用隔离电源，但其机构及制造工艺因素使其隔离性并不理想。实际上，由于分布参数特别是分布电容的存在，隔离是不可能的。TexasInstruments510-1101ASEABROWNBOVERI3HAA2400-002NSPP3HAA2400002TexasInstrument560TProcessorAMETEKZF2-480-60-UB-​01USPPZF248060UB01TEXASINSTRUMENTSPLC55PR8312000322USPP55PR8312000322SequencerinputoutputI/OTexasInstruments5TI10342TexasInstruments5TI-1021-1TEXASINSTRUMENTSPLC120-1112NSFP1201112ASEABROWNBOVERIYT204001-BNUSPPYT204001BNTEXASINSTRUMENTSPLC505-4232NSPP5054232ASEABROWNBOVERIYB161102-BSUSPPYB161102BSTexasInstrumentsProgrammerTI101Model100-3101NEWPERCEPTRONCAMERATRICAMSURFACESENSOR912-0007ASEABROWNBOVERIDSQC-314AUSPPDSQC314APERCEPTRON912-0007TexasInstrumentsPM550-400LoopAccessModulePM550400PERCEPTRONDIGITAL3TRICAM917-4014LASERDIGITALSURFACESENSORTEXASINSTRUMENTSPLC560-2120WUSPP5602120WTEXASINSTRUMENTSSiemensTIPN560-2128SiemensTI565PLCMemoryCard560-2134PanasonicServoDriverMBDDT2210NIBASEABROWNBOVERIYPQ-101EUSPPYPQ101ETEXASINSTRUMENTSPLC500-5006NSFP5005006ASEABROWNBOVERI58096067USPP58096067TexasInstrumentsRTU-AOT-1AnalogOutputBoard520-066PANASONICMSDA153D1AACSERVODRIVER1.5kwPanasonicMinasMQDZ023A1A200WattACServoDriverMotorDriveSIEMENS6ES7-412-2XG04​-0AB0USPP6ES74122XG040A​B0PanasonicMSD203A1VACServoDriverGENERALELECTRICCK08CE311JNSFPCK08CE311JGENERALELECTRIC02703154-10FTUSPP0270315410FTTEXASINSTRUMENTSPLC500-3103USPP5003103TexasInstrumentsRTU-HSA-1SystemCircuitBoardRTUHSA1TEXASINSTRUMENTSPLC5TI-1013USPP5TI1013GUTICOR76584-32USPP7658432TEXASINSTRUMENTSPLC2497284USPP2497284MKSINSTRUMENTSE28BU5TBF1BUSPPE28BU5TBF1BPanasonicACServoMotorM***041AJAFreeShipTexasInstruments565-2120TEXASINSTRUMENTSPLCPM550-100USPPPM550100ALLENBRADLEY2755-T4NSFP2755T4ASEABROWNBOVERILC820TL-R0012USPPLC820TLR0012ASEABROWNBOVERIOETL-NF1600SWUSPPOETLNF1600SWTEXASINSTRUMENTSPLC505-4732USPP5054732PanasonicACServoMotorMFA100MB5NSA_MFA100MB5NSATEXASINSTRUMENTSPLCRTU-8635-SSDUSPPRTU8635SSDTEXASINSTRUMENTSPLC530T-1104USPP530T1104ASEABROWNBOVERI57310001-S/5USPP57310001S5FINCORACE-F-460V--​7.5HPNSPPACEF460V75HPAPEXDYNAMICSINCAFR075-S2-P2USPPAFR075S2P2ALLENBRADLEY810-A04CNSFP810A04CASEABROWNBOVERIHIEE320604R1NSFPHIEE320604R1SiemensTI530C-1104PLCController530C-1104GENERALELECTRICSAM204A1AUSPPSAM204A1ATexasInstruments505-5103TurboParisonHITACHIGPCL01HUSPPGPCL01HTEXASINSTRUMENTSPLC505-6202NSFP5056202TEXASINSTRUMENTSPLC505-6830NSFP5056830PanasonicMADDT1207003ACServo200-240VACALLENBRADLEY20BD1P1A0AYNAN​A0NSPP20BD1P1A0AYNAN​A0MITSUBISHIMDS-A-CR-55USPPMDSACR55TEXASINSTRUMENTSPLC7MT-700NSPP7MT700PanasonicMSD011EAACServoDriveSIEMENSTEXASINSTRUMENTSSYSTEM505FUJIELECTRICUG520H-VC1ZUUSPPUG520HVC1ZUPanasonicACServoMotorM***A102A1G1kW220VFreeShipRELIANCEELECTRIC5711BNSPP5711BALLENBRADLEY8600-2158SUSPP86002158SPanasonicACServoMotorMHMA102P1CFreeShiptexasinstruments500-5035PROGRAMMABLEBASICMODULEPANASONICMFA024LA2NSACSERVOMOTORWARNERELECTRIC5371-273-028USPP5371273028505-7038TexasInstruments/Si​emensTI5057038R33SENSORIK4031NSPP4031ASEABROWNBOVERI57310001-FHUSPP57310001FHTEXASINSTRUMENTSPLC5TI-1029-1USPP5TI10291ASEABROWNBOVERIP1040QNSFPP1040QSQUAREDTVS-2EMA12ANSFPTVS2EMA12A)
