1764-MM21764-MM21764-MM2根据硬件结构的不同，可以将PLC分为整体式、模块式和混合式。1.整体式PLC整体式又叫做单元式或机箱式，它的体积小、价格低，对箱体式PLC，有一块CPU板、I/O板、显示面板、内存块、电源等，当然按CPU性能分成若干型号，并按I/O点数又有若干规格。对模块式PLC，有CPU模块、I/O模块、内存、电源模块、底板或机架。无任哪种结构类型的PLC，都属于总线式开放型结构，其I/O能力可按用户需要进行扩展与组合。2.模块式PLC大、中型PLC一般采用模块式结构，它由机架和模块组成，模块插在模块插座上，后者焊接在机架中的总线连接板上，有不同槽数的机架供用户选用，如果一个机架容纳不下选用的模块，可以增设一个或数个扩展机架，各机架之间用接口模块和电缆相连。用户可以选用不同档次的CPU模块、品种繁多的I/O模块和特殊功能块，对硬件配置的选择余地较大，维修时更换模块也很方便。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！！！————————————————————————————————NortelI2002POEIPPhoneNTDU91BB70NTDU91CharcoalNortelNTRH30AARLSE15NortelNTCA06ZKS/DMSOC192OPTTRMTRNortelBayNetworksBLN/BCN1000B-LXFRE4-PPCAG2204026NortelBCMDigitalDrop&InsertMUXMediaBayModuleNortelAL1001a05-e5BayStack5520-48SwitchNortelNT5C05CE61200ARectifierNortelBusinessPhoneSystemPackage#4w/1yrWarrantyNortelAL1001E06-e5BAYSTACK552024PORTSWITCHnewNortelBCM4004.0BaseSystem-Standard-NT7B10AAFVNortelNetworksOpteraMetro5200NT0H50AANortelAL1001e05-e5BayStack5520-48routingswitchNORTELPassport8006ChassisDS1402002Nortel,NTC06621KTE6BCM4004.0TO6.0H/WANDS/WUPNortelBLN-25280QuadPortSynchronousLinkModuleNortelNorstarCICS4x16Systemw/CallPilot100VoicemIBM32R1860-IBMNortelCopperGigabitEtheNortelBCM400PBXD***32+,DTM,GATM832HandsetsNortelNorthernMeridianMailNode1MEMVP/GSPESBCNTNortelBCM4003.7BCM400R3.780vm3ip2voipgatewayNortelI2004NonPoeNTEX00BANTEX00NortelOC3/STM-1MultimodeATM-IPFunctionProcessorNortelBCM2003.7BCM200R3.7Callcenter48vm32umIBM(32R1860)NortelLayer2/3CopperGbESwitchNortel,AL4500E02-E6ETHERNETROUTINGSWITCH4550TNortelNTCA15AAUniOSC1480/1510nmOSCCardNewNortelNT5D67CBE5RemoteMiniCarrierInterfaceT1NortelBCM4004.0BCM400R4.0R440vm2voipgwayMCDNNortelI2004NTDU82IconKeysCharcoalwpoeadaptorNortelI2004IPPhoneCharcoalBezelwPoeAdaptorNortelI2004NTDU82dualportipphonew/poeadaptorNewNortelNorstarT7316ET7316EPhoneNT8B27JAAANortelI2004NTDU82w/poeadaptorreplaceNTDU92BB70NORTELPASSPORT8692SFROUTINGMODULEDS1404065-E5MCKCitelE-7000T-RUM24PortNortel***aya7000RemoteNortelBCM450IPTelephony-32SeatCodeNTC01071KCNortelBCM450IPTelephonyClient-32SeatNTC01071KCNortelBayNetworks4-Port10/100b-TFRE4AG2204017BLNIbmNortelCopperGigabitEthernetSwitchModule-6XNortelEB1639A170-E5SecureSwitch4050EB1639170-E5Lotof(20)NEWNorstarNortelT7316ETelepNT8B27CharNORTELBASICCALLCENTERAUTHORIZATIONCODENORTELBCM50BASICCALLCENTERSWAUTHORIZATIONCODEAgilestar-AA1419066-E6-AS-ForNortel-NewinBoxNORTELACCELAR8624FXEXPANSIONMODULEDS1404005NortelDS1404065-e58692sfROUTINGSWITCHMODULELGAria-130LG-NortelPBXLoadedwithCa***NORTELETHERNETSWITCH470-48TWITH48AL2012E34E5NortelI2004NTDU82IconKeysCharcoalwPCPortPSNortelAL4500E12-e6POEroutingswitch4550T48portNortelI2004IPPhoneCharcoalBezelwPCPortPSNortel5520-24T-PWREthernetSwitchAL1001E06-E5~STSI***aya/Nortel4526T-PWR24-PortPoESwitchAL4500E13-E6)
