1794-OG161794-OG161794-OG16输入输出信息变换、可靠物理实现，可以说是PLC实现控制的两个基本要点。输入输出信息变换靠运行存储于PLC内存中的程序实现。PLC程序既有生产厂家的系统程序(不可更改)，又有用户自行开发的应用（用户）程序。系统程序提供运行平台，同时，还为PLC程序可靠运行及信号与信息转换进行必要的公共处理。用户程序由用户按控制要求设计。什么样的控制要求，就应有什么样的用户程序。可靠物理实现主要靠输人（INPUT）及输出（OUTPUT）电路。PLC的I/O电路，都是专门设计的。输入电路要对输入信号进行滤波，以去掉高频干扰。而且与内部计算机电路在电上是隔离的，靠光耦元件建立联系。输出电路内外也是电隔离的，靠光耦元件或输出继电器建立联系。输出电路还要进行功率放大，以足以带动一般的工业控制元器件，如电磁阀、接触器等等。I/O电路是很多的，每一输入点或输出点都要有一个I或O电路。PLC有多I/O用点，一般也就有多少个I/O用电路。但由于它们都是由高度集成化的电路组成的，所以，所占体积并不大。【***】【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***ayaLucentPartnerACSProcR3.0308ECR3.0***ayaLucentDefinityATMInterfaceTN2305BHV2F19NEW***ayaLucentDefinityIPMediaProcessorBoardTN2302APLucent***ayaDefinityTN795ONE/IP600ProcessorV5Lucent***ayaDefinityTN767CDS1InterfaceCardV24***ayaLucentPartnerMessagingR1.0modw/2portcardLucent***ayaDefinityTN2793B24-PortAnalog***ayaLucentPagePacPlusAmplicenterD100PagingAmpli4705-072***AYALUCENTP334T48PORT10/100SWITCH***AYALUCENTDEFINITYUN331C:ProcessorCardATT-***ayaLucentMerlinMagixProcessorW/CKE5Processo***AYALUCENT70020167648-PORTSWITCHCAJUNP334T-48V***ayaLucentACS6.0PartnerOfficePhoneSystemAT&TLucent***ayaP333T-PWR24Port10/100PoweredSwitchAT&T/Lucent/***a​yaTranstalkMDW9031BlackWireless4BLucent***ayaDefinityTN2214CP24-PortDigitalCircuit***ayaLucentDefinity26C1SelectorC***oleRefurbished***AYALUCENTM8008R-1000GB8PORTGIGABITMODULENEW***AYALUCENTM8004R-1000GB4PORTL3GIGABITMODULENEW***ayaCajunP334T48-PortSwitch***ayaCajun10864445148-PortSwitch***ayaCajun4705-07248-PortSwitchNewR7AT&TLucent***ayaPartnerACSProcessor5X9Lucent***ayaPartnerACS8.0PhoneSystemProcessor***aya/LucentDefinity-TN570DExpansionInterface3x***aya/Lucent-TN2214B2-wireDigitalCircuitPack***AYALUCENTMERLINMESSAGING12-PORTCARD108679549AT&T/Lucent/***a​yaPartnerMailVS539C32Port10MailbLUCENTAT&T***AYATELEPHONESYSTEM15PHONESLucent***ayaCajunM8008R-1000GBGigabitP880P882L3***aya/LucentDefinity-TN2215AnalogLineLucent/***ayaTN279324-PortAnalogCircuitPack***aya/Lucent-TN2214CP24-portDigitalCircuitPack***ayaLucentSwitchModuleCajunX330F2X330STKX330L2Lucent***ayaDEFATMFiberOpticKitMS2SC-SC107198665AT&T/Lucent/***a​yaPArtnerVoiceMessaging(PVM)1000288Lucent/***ayaIntuityMAP/100PMAP100PVoiceMailSystLotof25Lucent***aya6416D+MGrayTelephone***ayaLucentM32-100TM770ATMModularSwitchModuleLucent***ayaDefinityTN795ONE/IP600ProcessorV4PARTNERMAILVSR1.0W/EXPANSIONCARDforLUCENT/***AYAAT&T/Lucent/***a​yaPartnerACS103P1(28)T1ModuleACS***ayaLucentPartnerMailVSR5VoicemailModule***ayaLucent120A4CSUDSULUCENT***AYATRANSTALK9031PHONE+566RADIO+CHARGEBASE***ayaLucentDefinityPhoneSystem***ayaLucentAT&TDefinityDS1TieTrunkTN722BV6LUCENT***AYAMERLINMAGIXPROCESSOR617U33-KMODULE=)LOTOF29Lucent***aya6416D+GrayTelephone***ayaLucentDefinityTN793BV824PortAnalogTN793BBrandNew***aya/LucentM460ML-SPVAT&T/Lucent/***a​yaLegend391A2PowerUnitPowerSupplyAT&TLucent***ayaPartnerACS103G13(28)R5freeshipAT&T/Lucent/***a​yaPartnerII539B15ProcessorModuleVe***AYACALLMASTERIVLUCENTDEFINITY603F1603G1=)***ayaLucentTN2793BV224-PortAnalogCard***ayaLucentTN2793V424-PortAnalogCard***ayaLucent9640IPTelephoneRefurbishedLucent/***ayaTN786BPocessorw/CPP1AT&T/Lucent/***a​yaSpirit6030-308308BasicSystem3LiLUCENT***AYA18DPHONES***ayaLucentTelecomSwitchNodeINTFTN573BV4LUCENT***AYAPARTNERACS308ECR3.0EXPANSIONMODULELUCENTTN2224CP2WIREDIGITALLINECARDDEFINITYLucent***aya6416D+GrayTelephone***ayaLucentTelecomSwitchNodeINTFTN573BV3***aya/LucentDEFINITYTN750BTN750CAnnouncement***AYACAJUNP333R-48VW/X330STK&X330-OC12F1LUCE​NT***AYALUCENTDEFINITYTN2211***ayaLucentDefinityTN570DExpansionInterface***ayaLucentDefinityTN2312APIPServerInterface***ayaLucentDefinity120A1CSUDataUnit***ayaLucentDefinityTN464GPDS1PRICard***ayaLucentDefinityTN2302APHV11IPMedProLucent***ayaDefinityTN793B24PortAnalogV2Card***aya/LucentDefinity-TN573BPOLYCOMLucentSOUNDSTATIONEX***ayaDefinity+2xMICs***ayaLucent9650IPTelephoneNewLucent***ayaTN801BMAPDV3AnalogGatewayLineModuleLucentAT&T***ayaMerlinLegend408GS/LS-MLXSystemAT&T/Lucent/***a​yaDefinity843ExtenderSwitchModuleMAT&T/Lucent/***a​yaLegend391C1PowerUnitPowerSupplyAT&T/Lucent/***a​yaLegend391A1PowerUnitPowerSupplyAT&T/Lucent/***a​yaPartnerII539A8ProcessorModuleVerAT&T/Lucent/***a​yaPartnermail107884363VSR4ExpansionAT&T/Lucent/***a​yaDefinityPG-5E385-1087249078MEGR9***ayaLucentPartnerACS6ProcessorPBXPhoneSystem***ayaLucentDefinityIPMediaProcessorHV3/TN2302APZ14LOTOF6LUCENTAT&T***AYAMERLIN408GS/LS-MLXNEW***ayaLucentAT&TAnnouncementTN750CV13***ayaLucentAT&TAnnouncementTN750CV9***ayaLucentAT&TMAPDTN801V1REPAIRAT&T/Lucent/***a​yaMerlin4104Line10StationKSULucent/***ayaTN2214B2-WireDigitalCircuitPack***aya/LucentTN2402Processor***ayaLucentAT&TAnnouncementTN750CV8)
