1794-IRT8XT1794-IRT8XT1794-IRT8XT屏蔽层、接地线和大地有可能构成闭合环路，在变化磁场的作用下，屏蔽层内又会出现感应电流，通过屏蔽层与芯线之间的耦合，干扰信号回路。若系统地与其他接地处理混乱，所产生的地环流就可能在地线上产生不等电位分布，影响PLC内逻辑电路和模拟电路的正常工作。PLC工作的逻辑电压干扰容限较低，逻辑地电位的分布干扰容易影响PLC的逻辑运算和数据存储，造成数据混乱、程序跑飞或死机。模拟地电位的分布将导致测量精度下降，引起对信号测控的严重失真和误动作。安全地或电源接地：将电源线接地端和柜体连线接地为安全接地。如电源漏电或柜体带电，可从安全接地导入地下，不会对人造成伤害。系统接地：PLC控制器为了与所控的各个设备同电位而接地，叫系统接地。接地电阻值不得大于4Ω，一般需将PLC设备系统地和控制柜内开关电源负端接在一起，作为控制系统地。信号与屏蔽接地：一般要求信号线必须要有惟一的参考地即“单点接地”，屏蔽电缆遇到有可能产生传导干扰的场合，也要在就地或者控制室***接地，防止形成“地环路”。【***】【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NEWREXROTHINDRAMAT2AD104D-B35OB1-​FS06-B2N1MOTORINDRAMATREXROTHSERVODRIVEHDS041-W200N-HS12-0Rexroth4WS2EM10-41/60B​2T315Z8BMServoValveRebuiltA10VO71DFR/31L-​PSC92K02AXIALPISTONPUMPBOSCHREXROTHAA2FM56/61W-VSD​520AXIALPISTONMOTORBOSCHREXROTHREXROTH0608841030NSPP0608841030RexrothHydraulicServoValveRZ06-58334-10V5000RAMA2FE45/61W-VZL0​27PISTONMOTORBOSCHREXROTHREXROTH0-608-820-092NSPP0608820092MKD112B-024-GG0​-BNREXROTHSERVOMKD112B024GG0BNRexrothFibroHydraulicPumpw/ControllerforGrinderREXROTH0608841033NSFP0608841033NEWREXROTHINDRAMATMHD090B-058-PP1​-UNSERVOMOTORRexrothHydraulicPowerUnit22GPM20HP3625PSIAA10VSOREXROTHINDRAMATMOTORMAC112C-0-HD-3-​C/130-B-0/S005A10V071DFR1/31R​-PRC62-K68PUMPBOSCHREXROTHRexroth4WRTE16E1ProportionalValve4WRTE-42MRebuiltREXROTHRD521-4N-001-L-​NNUSPPRD5214N001LNNNEWRexrothIndramatServoMotorMHD112D-027-PP0​-BNA10VO71DR/31L-P​SC91N00PUMPBOSCHREXROTHRexrothHydraulicServoValve4WS2EM10-45/10B#21497AA2FM56/61W-VSD​520FIXEDDIPLACEMENTBOSCHREXROTHREXROTH0608841030USPP0608841030REXROTHNUTRUNNERECH57-MG0-608-841-011REXROTHA10VS0100DRPK62K03UchidaBoschRexrothHydraulicPumpMotorCS-24-3323VREXROTH47S621HYDRAULICUNIT,NEWNEWREXROTH4WRE10W75-20/G2​4K4/VDIRECTIONALVALVENEWREXROTHHYDRAULICPUMPSYDFE1-2X/140R-​PKD62N00-0000RexrothR0055188810LinearModuleWithServoMotorREXROTHINDRAMATSERVOMDD115A-N-030-N​2M-130GA1REMANBoschRexrothServoAmplifierLTU3500608750108newBoschRexrothHydraulicVanepumpPSVPSSF20HRM56NIBBOSCHREXROTHECH57-MGELECTRONICTORQUENUTRUNNERRexrothServoValve4WS2EM6-12/0F12ET315Z17EM-1​0NewRexroth4WRZE10E85-70/6EG24N9E​TK31/A1D3VValveNOSRexrothServoValve4WRDE16-51/MNewRexrothServoValveVORSTEUERVENTIL-21/4WRDE10-52/VRexrothProportionalValve4WRE6E16-1224K4MNewREXROTHVT-HNC100-1-22/​W-08-0-0USPPVTHNC100122W080​0LA10VO71DFR1/31​R-PSC91N00PISTONPUMPREXROTHBoschRexroth/IndramatDDS3.1-W030-DS0​1-01-FWA10VO71DRG/31L-​PRC92K08PISTONPUMPBOSCHREXROTHMSK100D-0300-NN​-S1-BG2-NNNNREXROTHRexrothHydraulicServoValve4WS2EM10-45/10B#21498REXROTH0-608-841011USPP0608841011REXROTH0-608-841016USPP0608841016REXROTHINDRAMATDKC02.3-040-7-F​WNEWDKC0230407FWNEWREXROTHINDRAMATMHD093C-058-PGO​-ANSERVOMOTORAA2FM45/61W-VSD​510AXISPISTONMOTORREXROTHA10VO71DR/31R-P​SC92N00PISTONPUMPBOSCHREXROTHA10VO71DFR/31R-​PSC92N00AXIALPISTONPUMPBOSCHREXROTHNEWREXROTHINDRAMATMHD112B-024-PG0​-BNSERVOMOTORNEWREXROTHINDRAMATMHD090B-035-PG0​-UNSERVOMOTORNEW/REFURBREXROTHINDRAMATDKC04.3-040-7-F​WSERVODRIVREXROTHINDRAMATSERVOMAC093B-0-0S-3-​C/130-A-0/S001)
