1794-CE31794-CE31794-CE33.2综合抗干扰设计主要考虑来自系统外部的几种如果***措施。主要内容包括：对PLC系统及外引线进行屏蔽以防空间辐射电磁干扰；对外引线进行隔离、滤波，特别是原理动力电缆，分层布置，以防通过外引线引入传导电磁干扰；正确设计接地点和接地装置，完善接地系统。另外还必须利用软件手段，进一步提高系统的安全可靠性。4主要抗干扰措施4.1采用性能优良的电源，***电网引入的干扰在PLC控制系统中，电源占有极重要的地位。电网干扰串入PLC控制系统主要通过PLC系统的供电电源（如CPU电源、I/O电源等）、变送器供电电源和与PLC系统具有直接电气连接的仪表供电电源等耦合进入的。现在，对于PLC系统供电的电源，一般都采用隔离性能较好电源，而对于变送器供电的电源和PLC系统有直接电气连接的仪表的供电电源，并没受到足够的重视，虽然采取了一定的隔离措施，但普遍还不够，主要是使用的隔离变压器分布参数大，***干扰能力差，经电源耦合而串入共模干扰、差模干扰。所以，对于变送器和共用信号仪表供电应选择分布电容小、***带大（如采用多次隔离和屏蔽及漏感技术）的配电器，以减少PLC系统的干扰。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————TRICONEX3636RTRICONEXTRICON8111TRICONEXTRICONEXPANSIONCHASSISGOULDMODICONAS-B840-108ABBIRBROBOT3HAB5956-1TRICONEXTRICON8110MAINCHASSISHIGHDENSITYMODICONAS-B824-016OUTPUTTRUEHIGHMODULEMODICONAS-J878-000MODEMMODULETRICONEXTRICON4000029-020ConnectorCableTRICONEX4409***MHONEYWELLMODULENIBTRICONEXTRICON3000142-220SETTERMAL5VCURRENTTRICONEX2652DIGITALOUTPUTMODULENIBTRICONEXTRICON4000029-025ConnectorCableTRICONEX4351ACOMMUNICATIONMODULENIBMODICONAS-C921-101COMPROCESSORMODULETRICONEX2750INTERFACECONNECTORMODULENIBMODICONPC-O984-480PROCESSORMODULEMODICONS908REMOTEI/OPROCESSORMODICONMA-P933-000POWERSUPPLYMODULEMODICONAS-B864-001OUTPUTMODULEMODICONAS-B814-108SELECTABLEN.O/N.C.MODULETRICONEXTRICONMAINCHASSISMODICONC916-100C984CPUMODULEMODICON***09-022MEMORYMODULETRICONEXTRICON4000029-010MODICONAS-B805-016MODICONAS-B825-016INPUTMODULEMODICONAS-B820-008OUTPUTMODULETRICONEX2553DIGITALTRICONEX2651DIGITALTRICONEXTRICON3614E24VDCTRICONEX3008MPMODICONAS-B825-016INPUTMODULEMODICONTSXQUANTUM***I14003000***I1400300TRICONEX3501E115VAC/DCDIGITALINPUTMODULETRICONEXTRICON8300APOWERMODULE120VAC/DCTRICONEXTRICON4409Honeywell***MMODICONAS-BDAP-210OUTPUTMODULEMODICONAS-B827-032INPUTMODULETRICONEX4107EICMNIBTRICONEXTRICON2652CONNECTIONMODULETRICONEXTRICON8300POWERMODULE120VAC/DCTRICONEXTRICON2755TRICONSETTERMITC16PTMODULETRICONEX3006EMPIIMAINPROCESSORIIENHANCED2MBTRICONEXTRICON2652CONNECTIONMODULETRICONEX2553INPUTDIGITAL24VDCMODULETRICONEXTRICON8305APOWERMODULE120VAC/DCMODICONPC-E984-485PROGRAMMABLECONTROLERTRICONEXTRICON3601E115VACDIGITALOUTPUTTRICONEXTRICON3003EMPIIV7EMPII1MBMODULEMODICONAS-J478-010STANDALONEMODEMMODICONAS-B864-001OUTPUTMODULETRICONEX4200RemoteExtenderModuleTRICONEXTRICON2652OUTPUTTRICONEXTRICON4119AEICMMODULETRICONEXTRICON4107EICMTRICONEX27002700-2MODULENIBINTERFACEHPTB/32/TR-AI-0​1TRICONEXFTA+MUX2700TRICONEXTRICON4351ATCMCOMMUNICATIONMODULEHARTINTERFACEHPTB/32/TR-DO-0​1TRICONEXFTA+MUX2700TRICONEXTRICON3008MPMAINPROCESSORTRICONEXTRICON3604E24VDCDIGITALOUTPUTMODULETRICONEXTRICON8112RXMCHASSISHIGHDENSITYNEWABBIRB6400ROBOTAXIS1MOTOR3HAB6738-1SickOpticLCU-AM7022760SafetyInterface/PowerSupplyTRICONEXTRICON3708EISOLATEDTHERMOCOUPLEMODULETRICONEXTRICON3636RRELAYOUTPUTMODULEDRYCONTACTTRICONEXTRICON362424VDCSUPERVISEDDIGITALOUTPUTTRICONEXTRICON3700ANALOGINPUTMODULE0-5VDC32PTFOXBOROFLOWMETER931HA-SIBA-PPJ-​GLTRICONEXTRICON3503E24VAC/DCDIGITALINPUTTRICON8305POWERMODULE120VAC/DCFOXBOROMAGNETICFLOWTUBE8002A-WPR-HJGCN​Z-ANEWFoxboroPressureTran***itterIDP10-D47B21F-M​1L1C1K1NEWABBIRBROBOTAXIS4MOTOR3HAB6620-1Allen-Bradley1756-PSCAMINTCONDITION!FOXBOROMAGNETICFLOWTUBE8002A-WPR-HJGCN​Z-AFOXBOROPRESSURETRAN***ITTERIDP10-D20D21C-C​1K1FOXBOROPRESSURETRAN***ITTERIDP10-D20D21C-C​1K1TRICONEXTRICON8310POWERMODULE120VAC/DCNewBARKSDALET2H-H154TemperatureSwitcheFSPHOENIXTemperaturetransducerMCR-TE/J/K/I-E-NC)
