1794-OB16D1794-OB16D1794-OB16D(2)PLC系统中干扰的主要来源及途径a.强电干扰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，它将受到所有空间电磁干扰而在线路上感应电压。尤其是电网内部的变化，刀开关操作浪涌、大型电力设备起停、交直流传动装置引起的谐波、电网短路暂态冲击等，都通过输电线路传到电源原边。b.柜内干扰控制柜内的高压电器，大的电***负载，混乱的布线都容易对PLC造成一定程度的干扰。c.来自信号线引入的干扰与PLC控制系统连接的各类信号传输线，除了传输有效的各类信息之外，总会有外部干扰信号***。此干扰主要有两种途径：一是通过变送器供电电源或共用信号仪表的供电电源串入的电网干扰，这往往被忽视；二是信号线受空间电磁辐射感应的干扰，即信号线上的外部感应干扰，这是很严重的。由信号引入干扰会引起I/O信号工作异常和测量精度大大降低，严重时将引起元器件损伤。【***】【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RELIANCE(DC1-70U)1-2HPVSMOTORDRIVECONTROLLERNICERelianceElectricMotor100HP1785RPMEfficient445URelianceElectricMotor75HP1785RPMEfficient444URELIANCE(DC1-40U)1-2HPVSMOTORDRIVECONTROLLERNICERelianceElectricMotor250HP1785RPMEfficient449URelianceElectric5HPACVSDriveGP-12001A***005UReliance606Series304050GalWaterHeaterUChooseRelianceElectricDover40HPACMotor1765RPM324URelianceElectricDCDriveFlexpakPlus14C103-1U3HpRelianceVFDVariableSpeedDrive230v3p5HP1AC2105URelianceElectricDC1-62UDCMotorControllerDC162URelianceElectricDCDriveFlexpakPlus14C102-1U1.5HpRELIANCEMOTOR326U15HP15HP880RPM3PH2MAFT1399G1RelianceDC1-62UDC1VSDRIVEDC162U1-2HPCONTROLLERRELIANCEDC1-40UDCDRIVERelianceElectricMotor250HP1785RPMEfficient449URELIANCE1AC2002UACDRIVE2HPVSD220/230Vvolts7.5aVERYNICERELIANCE.75HPFLEXPAKPLUSDRIVE14C106-1URelianceElectricRPMIII7.5HPDCMotorT18R1301URELIANCEVS-DRIVEDC2-62UDCDRIVE1-2HP90/180VRelianceElectricMotor250HP1785RPMEfficient449Ureliancedc1-70uvariablespeeddcmotordrivecontrolRELIANCEELECTRICFLEXPAKPLUSVSDRIVE14C303URelianceElectricDCDriveFlexpakPlus14C108-1U3HpbRELIANCE1AC2002U-RR-014A-CVSDRIVE2.9KVA2HP@0.8PFRELIANCEDC2-70UDC2MOTORCONTROLLERVSDRIVERELIANCEELECTRICP56H5069UA-CMOTOR1/2HP3PHNIBRELIANCEVSMINIPAKPLUSMOTORDRIVE14C11U1.5HPRELIANCEVS-DRIVEDC1-62UDCDRIVE1-2HP90/180VRelianceElectric1A***002UGP-12002HPACVSDrive2HPRELIANCEDC2-90UVSDRIVEDC2MOTORCONTROLLERRELIANCEMOTOR254U5HP1170RPM3PHTEFC460VOLTRELIANCEDC2-70UDC2MOTORCONTROLLERVSDRIVERelianceElectric3HPACVSDrive-1AC2003URELIANCEELECTRICRESISTOR63481-6UReliance14C102UFlexPakPlusVSDCPowerDrive1.5HPCLARK-RELIANCEVALVESEAT#P3316-UNSN4820011913818RELIANCE7.5KVAACVFDDRIVE1A***007UGP-1200460VOLTRELIANCEELECTRICRESISTOR63481-6URELIANCEP56H1437U1HP3/60/208-230/46​01725RPMFA56RelianceElectric3HPACVSDriveGP-12001A***103URELIANCE1AC2001UACDRIVE1HPVSD230VRelianceElectric3HPACVSDriveGP-12001A***103URelianceElectricMotor250HP1785RPMEfficient449URELIANCEHR2000BrushlessACServoController3RA2015URELIANCEELECTRICGV3000/SE-11-3/​8X16-5/8X4-1/2-​COVERURelianceDC1-40UESCORTEXPLORERF-150-F-350ATERNATORNewRelianceElectricEMasterACMotorB79U3686M-SZ3RelianceACDriveDBUnit1DB4010U-DBCC-0​04USEDRELIANCEELECTRIC63481-2U750WLNEWRELIANCEP56H1319U-XT3/4HP1725RPM208-230/460VRELIANCEELECTRICACDRIVE1AC2002UNEWRELIANCEELECTRICIMPACKPLUSVSDRIVE8C10URelianceDriveFujiET1275Transistor15A1000v1URelianceElectric1AC2103UGP1000ACDriveRELIANCEELECTRICACDRIVE1AC2002U(1671)RELIANCEELECTRICACMOTORP56H1441U-YS1HP3PRELIANCEELECTRIC1HPACDRIVE230VOLT1AC2101U)
