A06B-6093-H101输入模块A06B-6093-H101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。Panasonic200WACServoDriveMSD021A1XUFreeShipPanasonicACServoMotorMHMD082G1U750WNewinBoxFreeShipASEABROWNBOVERIACS401-6020-32USPPACS401602032PanasonicACServoMotorM***042A1GFreeShipPanasonicACServoMotorM***082D1ATexasInstruments2490871ProcessorBoardPROCESSCONTROLCORPC1538USPPC1538ASEABROWNBOVERIYT204001-KAUSPPYT204001KAPanasonicACServoDriverMDDHT5540FreeShipTEXASINSTRUMENTSPLC500-5892NSFP5005892TEXASINSTRUMENTSPLC944935-15V/AEUSPP94493515VAESQUARED3050-SD-300-X1USPP3050SD300X1TEXASINSTRUMENTSVPU500-3104VIDEOPROGRAMMINGUNITASEABROWNBOVERIEH700-C1USPPEH700C1(AA01)ACSERVODRIVERPANASONICMATSUSHITAMSD021P1EA01WORKINGPANASONICSERVODRIVERMfDDTA390L013KWPerceptronMiniCamSurfaceSensorASEABROWNBOVERIEHDB-360C1USPPEHDB360C1PanasonicACServoMotorM***A021A1UFreeShipTRON630264USPP630264PanasonicMGDA093A1AACSERVODRIVERFreeShipTEXASINSTRUMENTSPLC505-4132NSPP5054132TexasInstrumentsRTU-T059-TTERMINATIONPANELALLENBRADLEY809-A12ENSPP809A12EOMRONNT631C-ST141B-​***USPPNT631CST141BEV​2ASEABROWNBOVERIYT212001-BR-YB​KA70-15USPPYT212001BRYBKA​70TEXASINSTRUMENTSPLC2587695-8014USPP25876958014ASEABROWNBOVERIS6N600BW-4USPPS6N600BW4SIEMENS6AG4040-0AG30-​0PA0NSFP6AG40400AG300P​A0ASEABROWNBOVERIMEM86-192KNSFPMEM86192KASEABROWNBOVERIQDBB-153MUSPPQDBB153MGENERALELECTRIC755X045015USPP755X045015SQUAREDLAF3640032MV10​27USPPLAF3640032MV10​27PanasonicACServoDriverMDDA303A1AFreeShipASEABROWNBOVERIK7WFNSFPK7WFTEXASINSTRUMENTSPLC505-6830USPP5056830TEXASINSTRUMENTSPLC2491940-0001USPP24919400001ASEABROWNBOVERI3HAA2121-2NSPP3HAA21212XYCOMXVME-661NSFPXVME661FANUCA06B-0143-B075USPPA06B0143B075HOFFMANC-SD302410SSNSPPCSD302410SSMITSUBISHIFR-A540-3.7K-N​AUSPPFRA54037KNASAJF//PANASONICM***D012P1TACSERVOMOTORUSED(AG01)PANASONICM***021ABFACSERVOMOTORWORKINGTEXASINSTRUMENTSPLC505-4616NSFP5054616ASEABROWNBOVERIDSDP-150USPPDSDP150PanasonicMSD153A1VACServoDriverALLENBRADLEY2711-B6C8USPP2711B6C8TEXASINSTRUMENTSPLC500-7201USPP5007201ASEABROWNBOVERI289B943A30NSFP289B943A30ASEABROWNBOVERI3BSE030230R1USPP3BSE030230R1ASEABROWNBOVERIACS401601132NSFPACS401601132TexasInstrumentsPM550-100CARRIERLA-01NA-030NSFPLA01NA030PanasonicACServoMotorM***082A1ENEWFreeShipExpeditedshippingailablePanasonicMQMZ012A2UACSERVOMOTORNEWASEABROWNBOVERIOES800L3NSPPOES800L3ALLENBRADLEY6158-AAAAAZAAZ​ZUSPP6158AAAAAZAAZZMODICONAS-J475-000NSFPASJ475000PanasonicACServoMotorMHMD082G1U750WNewinBoxFreeShipTexasInstrumentPM550-116ASEABROWNBOVERIEH550G-PRL11NSFPEH550GPRL11ASEABROWNBOVERIAPTBE-03USPPAPTBE03ASEABROWNBOVERISK-0015NSPPSK0015GEFANUCIC697ADC701USPPIC697ADC701TEXASINSTRUMENTS5TI-1032-2SEQUENCERMODULE5TI10322505-CP1434TFTexasInstrumentsSiemensTI505CP1434TFDETRONICSR9105-P5002USPPR9105P5002GETTYS120-166-005NSFP120166005TEXASINSTRUMENTSPLC505-5518USPP5055518ALLENBRADLEY512M-BJA6P-24RNSPP512MBJA6P24R)
