1794-STRT1ES模块1794-STRT1ES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。PanasonicACServoDriverMSDA083D1A61750WFreeShipTEXASINSTRUMENTSPLCPWB2490873-000​2CUSPPPWB24908730002​COnePanasonicServoDriverMBDDT2210N01FreeShip500-2109TexasInstrumentsTIDistributedBaseController5002109N742STR-410TTexasinstrumentsTILoaderSTR410TD-282INDUSTRIALELECTRONICDEVICESNDT-17TUSPPNDT17TSYMAX8881-MD2USPP8881MD2TexasInstruments46191PCBoardASEABROWNBOVERIAF260-20-22-72NSFPAF260202272FISHERROSEMOUNTDH6003X1USPPDH6003X1PanasonicACServoDriveMCDCT3312B12TexasInstruments305-01ABPanasonicServoMSD023A1XX&MotorM***022A1F200WINDRAMATMAC090A-0-RD-3​-D/110-A-0-S00​1USPPMAC090A0RD3D11​0ATEXASINSTRUMENTS500-5047-A5005047APanasonicMSD083A1XGACServoDriverPERCEPTRON911-0007ASEABROWNBOVERIACS201-2P7-3-0​0-10USPPACS2012P730010TRANSDUCERTECHNIQUESPLCLOADCELLTIO-3000TI0-3000TI-3000TEXASINSTRUMENTSPOWERSUPPLYPM550-2122461375-0001YASKAWAELECTRICSGMGH-30DCA6CNSFPSGMGH30DCA6CMKSINSTRUMENTSE28BU5TBF1BUSPPE28BU5TBF1BASEABROWNBOVERIACS401601132NSFPACS401601132ASEABROWNBOVERI069829-001USPP069829001DV80X220MR5PANASONICACSERVODRIVERDV80XINPUT200VOUTPUT2.2KW2500ENCODERASEABROWNBOVERI3ADT220071R000​6FNFP3ADT220071R000​6560-2128TITexasInstruments5602128TEXASINSTRUMENTSPLC505-4516NSPP5054516EXTORRXTPR200MNSFPXTPR200MRELIANCEELECTRIC0-49046USPP049046TEXASINSTRUMENTSPLC505-3516NSPP5053516SIEMENS6SE3290-0DC87-​0FA4USPP6SE32900DC870F​A4NIBTEXASINSTRUMENTS305-25NINPUTMODULENIBTEXASINSTRUMENTS305-25NINPUTMODULEASEABROWNBOVERIPSTB57060070USPPPSTB57060070PANASONICSERVODRIVERMfDDTA390L013KWGENERALELECTRIC193W-526AAG02USPP193W526AAG02PerceptronMiniCamSurfaceSensorTEXASINSTRUMENTSPLC500-6224NSFP5006224GETTYS120-166-005NSFP120166005TEXASINSTRUMENTSPLC530C-1104USPP530C1104TexasInstrumentsModelTI120PLCModel:120-1111TexasInstruments500-5037(AS01)MSDA083D1APANASONICACSERVODRIVEUSEDWORKINGPANASONICSERVODRIVERMEDDT7364L012.5KWNIOBRARAR&DCORPEPE5-DUSPPEPE5DReturns:NotacceptedBARBERCOLMANMP-9910USPPMP9910ASEABROWNBOVERIACS601-0016-4-​000B1500801USPPACS60100164000​B2TexasInstruments5TII/OExpander5TI-5500ModuleALLENBRADLEY1326-CFUT-150NSFP1326CFUT150APWMCLEAN28-0226-003USPP280226003TEXASINSTRUMENTSPLC949025-000USPP949025000TISIEMENSTEXASINSTRUMENTSDUALCOMMPORT500-5029ExpeditedshippingailableASEABROWNBOVERI57088621NSFP57088621SQUAREDMAP36500USPPMAP36500TEXASINSTRUMENTSPLC55CR9602001052USPP55CR9602001052PanasonicMatsushitaSERVOMOTORM***A012A1G100W60dayswarrantyASEABROWNBOVERI57360001-K/9USPP57360001K9PERCEPTRON912-0007USPP9120007TEXASINSTRUMENTSCVU-3604KEYBOARDCVU3604TEXASINSTRUMENTSPLC128-1111USPP1281111TexasInstruments575-6660PowerSupply&575-2102CPUMODin14slotTIRackTexasInstruments505PowerSupplyRackw/AccessoriesBROWNING107SC25-200DUSPP107SC25200DTEXASINSTRUMENTSPLCPM550-100USPPPM550100TEXASINSTRUMENTSPLC560-2132NSFP5602132TEXASINSTRUMENTSPLC505-6830USPP5056830CHINODB113M-000USPPDB113M000TEXASINSTRUMENTSPLCES150850-101AUSPPES150850101AALLENBRADLEY1772-ME8USPP1772ME8)
