IC697ALG230IC697ALG230IC697ALG230接地是提高电子设备电磁兼容性（EMC）的有效手段之一。正确的接地，既能***电磁干扰的影响，又能***设备向外发出干扰；而错误的接地，反而会引入严重的干扰信号，使PLC系统将无法正常工作。PLC控制系统的地线包括系统地、屏蔽地、交流地和保护地等。接地系统混乱对PLC系统的干扰主要是各个接地点电位分布不均，不同接地点间存在地电位差，引起地环路电流，影响系统正常工作。例如电缆屏蔽层必须一点接地，如果电缆屏蔽层两端A、B都接地，就存在地电位差，有电流流过屏蔽层，当发生异常状态如雷击时，地线电流将更大。★厦门泰尼电气有限公司★★联系人：小黄★★QQ：2917675397★★电话：0592-6809319★★手机：18950191386★★传真：0592-6890859（注小黄收）★★邮箱：2917675397@***.com★★地址：厦门市海沧区海沧街道滨湖一里7号2008室★JEVIDK7100DK7100220V5000WHEATINGELEMENTABB07NG60R1ProconticPowerSupplyGJV3074310R1NORTHROPGRUMMANNSNCANCELLERCIRCUITBOARD218771850NORTHROPGRUMMANNSNTRIGGERGENERATORCIRCUITBOARD21NORTHROPGRUMMANNSNCOMBINERDESTAGGERERCIRCUITBOARDNumatics34HLD4410PneumaticValve34HLD44101/2"NPTLFE2011C5-5020-4300PROCESSCONTROLLERAlcoEmerson222CB1-1/2B1-1/2BSolenoidValve1-1/2"DYNAMATICCONTROLCIRCUITBOARDCARDDRIVE15-530-6155Magnetekgpd515acmotordrive3phaseGPD515C-C003BALLUFFCONNECTIONCONTROLCABLEC04T8R19PB050MGEFanucAnalogInputModuleIC693ALG221J4PointCurreFiberglassWindowDoorSCREENScreening36"x600'CharFiberglassWindowDoorSCREENScreening40"x600'CharPARKERPRESSURECOMPENSATEDFLOWCONTROLVALVEPCCKCUTLERHAMMERPCCONTROLBOARD4D14810G01FOREASYSTARGalilMotionController1-AxisDMC1412DMC141290-240ELEKTRA-LINDAUElektrischeHeizsystemeHeatingSystemYASKAWACIRCUITBOARDCARDYPCT31182-1DYPCT311821DETPKSBMOTORCENTRIFUGALPUMPETABLOC-GN40-125/402GN104SIEMENS1LA01444FP21RGZP1HP230YY/460YELECTRICMOTORMazurczakCalorHeatCartridgePHK46-990/90-3,5/480DsKKSBMOTORCENTRIFUGALPUMPETABLOC-GN40-125/402GN104SIEMENSMT5000A5.0KVA5KVA5KVATRANSFORMERKSBMOTORCENTRIFUGALPUMPETABLOC-GN40-125/402GN104KSBMOTORCENTRIFUGALPUMPETABLOC-GN40-125/402GNI2-EclipseAutomaticGasShutoffValveSeries2000147561BAILEYMETERSMINILINELU1352ADRUMLEVELMODELBBALDORELECTRICMOTORM36041HP1HP208-230/460V3PHMONITOR6-8511-111SILOPATROLMODEL***USILOMONITORINGGRACOHOUSINGINTAKEFOOTVALVE206-617206617LOCNORTHROPGRUMMANSYNCHRONIZERCIRCUITBOARDCARD21877NORTHROPGRUMMANTRIGGERDRIVERCIRCUITBOARDCARD2187TURCKINDUCTIVEPROXIMITYRINGSENSORSWITCHBi-40-***SNORTHROPGRUMMANVIDEODRIVERCIRCUITBOARDCARD21877INGERSOLLRANDACTUATORVALVEMKP7-135221X4274FANUCB0.5/3000SERVOMOTORW/PS60-010-SHGEARBOXPARKERCOMPUMOTORSTEPPERMOTORCONTROLCONTROLLERDRIVALLENBRADLEYACDRIVE2.2KW2.2KW3HP3HP160-BA06PSDEUTCHEVANRIETSCHOTENBRAKESHOE100R+H100Y1853B.E.S.BULKEQUIPMENTBE-1320-2BVIBRATORYMOTORSHAKERLEUZELUMIFLEX46"MIRRORCOLUMNCURTAINMG-1050549110NORTONDOORCLOSER7700PTD8000PTD24VACRISONCIRCUITBOARDCARDMD-6MD6ISS79300-5202930GEC/ALPAKFE4105S701/110HP10HPELECTRICMOTOR470VDODGETIGEAR2GEARBOXSPEEDREDUCERRATIO50:10.7HP2NORDSK22N56C12.20:1RATIOGEARREDUCER139RPMNORDSK22N140TC16.75RATIORPM101GEARREDUCERRIETSCHOTENTWIFLEXAIRPNEUMATICBRAKESHOE100R+H100YorkEnergyElectrostaticWaterTreaterIS-1(10-01-20)ASCORED-HATIIBRASSSOLENOIDVALVE8220G02510.1W1"BELL&GOSSETTEFFLUENTSUMPPUMP2"NPT1BT003K046025VICKERSV21021-12HYDRAULICVANEPUMP1"NPTINPUT1/2"MULLERMARTINIOPERATORINTERFACECONTROLCONTROLLERPAWestinghouseMark75HKL3250CircuitBreaker250AmpSQUAREDOPENFLOORBOTTOMELECTRICALENCLOSURE30"x19"MURATACIRCUITBOARDCARDMODULEMVL-MPU-205MVLMPU205HEIDENHAINLOTOFPCBENCODEREQUIPMENTRELIANCE0-5188405188451884LSCAPLCMODULEBOARDNOSITTSTANDARD5-030-03-008-002HEATEXCHANGER30ASCON128400B07024VDC22WPIPEG1/8REBUILTSPECTREXSAFEYEOP-UF110SUVGASDETECTORAllenBradleyACDrive160-BA06NSF1P1SeriesCFRN7.06LANTECHCAROTRONDIGITALTHUMBWHEELTHUMBWHEELCIRCUITHONEYWELLTEMPERATURECONTROLLERDC3004-0-00A-1-00-0111TRUTZSCHLERCORRECTACARDMCCMCONTROLCCM-ECCME491-8RelianceCardpakPowerAmplifierCard0-49042-10490421RelianceCardpakDRIVERCard0-49011-90490119***MANLABORATORIESMODEL1560DUALPISTONPUMPSCHLAFHORST117-655791DIGITAL1-200BOARD/CARDNONAME48"x48"x84"STEELsecurityCAGEw/33-1/2"xDET-TRONICSFLAMEUVIRULTR***IOLETFIREFLAMEDETECTIODET-TRONICSFLAMEUVIRULTR***IOLETFIREFLAMEDETECTIOSCHLAFHORST117-656045PCBCONTROLBOARD/CARDNONAMESPEEDREDUCERGEARREDUCERH6-CCB040705193468SQUAREDSOLIDSTATELEVELSENSORCLASS9034TYPELSVFWASCOSOLENOIDVALVE8215B83120VOLT2"NPT)
