1770-SC输出模块;1770-SC输出模块;1770-SC输出模块PLC主要由CPU模块、输入模块、输出模块和编程器组成(见图1),有的PLC还可以配备特殊功能模块,用来完成某些特殊的任务。1.CPU模块CPU模块主要由微处理器(CPU芯片)和存储器组成。在PLC控制系统中厂CPU模块相当于人的大脑,它不断地采集输入信号,执行用户程序,刷新系统的输出;存储器用来储存程序和数据。2.I/O模块输入(1nput)模块和输出(Output)模块简称为I/O模块,它们是系统的眼、耳、手、脚,是联系外部现场设备和CPU模块的桥梁。输入模块用来接收和采集输入信号,开关量输入模块用来接收从按钮;选择开关、数字拨码开关、限位开关、接近开关、光电开关、压力继电器等过来的开关量输入信号;模拟量输入模块用来接收电位器、测速发电机和各种变送器提供的连续变化的模拟量电流、电压信号。开关量输出模块用来控制接触器、电磁阀、电磁铁、指示灯、数字显示装置和报警装置等输出设备,模拟量输出模块月手来控制调节阀、变频器等执行装置。图1PLC控制系统示意图CPU模块的工作电压一般是5V,而PLC的输入/输出信号电压一般较高,如直流24V和交流220V。从外部引入的尖峰电压和干扰噪声可能损坏CPU模块中的元器件,或使PLC不能正常工作。在I/O模块中,用光耦合器、光电晶闸管、小型继电器等器件来隔离PLC的内部电路和外部的I/O电路,I/O模块除了传递信号外,还有电平转换与隔离的作用。3.编程器编程器用来生成用户程序,并用它进行编辑、检查、修改和监视用户程序的执行情况。手持式编程器不能直接输入和编辑梯形图,只能输入和编辑指令表程序,因此又叫做指令编程器。它的体积小,价格便宜,一般用来给小型PLC编程,或者用于现场调试和维护。使用编程软件可以在计算机的屏幕上直接生成和编辑梯形图、指令表、功能块图和顺序功能图程序,并可以实现不同编程语言的相互转换。程序被编译后到PLC,也可以将PLC中的程序上传到计算机。程序可以存盘或打印,通过网络,还可以实现远程编程和传送。4.电源PLC一般使用220V交流电源或24V直流电源。内部的开关电源为各模块提供DC5V,±12V,24V等直流电源。小型PLC一般都可以为输入电路和外部的电子传感器(如接近开关)提供24V直流电源,驱动PLC负载的直流电源一般由用户提供。ASEABROWNBOVERIOETL-NF1600SWUSPPOETLNF1600SWNEWSIEMENS525-1102SIMATICTI525PLCCPUMOCULETEXASINSTRUMENTSPLC500-5114USPP5005114ALLENBRADLEY2711P-RDK10CUSPP2711PRDK10CPanasonicServoDriveMADR04311ANewinBoxFreeShip(AS01)MSD5A3A1XXVPANASONICACSERVODRIVEUSEDWORKINGTEXASINSTRUMENTSPLC555-1106USPP5551106PanasonicACServoMotorM***082A4BFreeShipNILFISKADVANCEGM-625USPPGM625(AB01)ACSERVODRIVERZ축DIRVERPANASONICMSDA041A1A07IRT4020MUSPP4020MALLENBRADLEY1336F-BRF100-AE-DE-HAS2USPP1336FBRF100AEDEHASEABROWNBOVERIOETL-NF600A-2SWNSFPOETLNF600A2SWTEXASINSTRUMENTSPLC505-4708NSFP5054708ASEABROWNBOVERI503349NSFP503349ASEABROWNBOVERIP-HC-BRC-30000000NSFPPHCBRC30000000PanasonicACServoMotorM***A04211AFreeShipMODICON610-MSA-210-30USPP610MSA21030SIEMENS/TEXASINSTRUMENTSTI305SERIESTI305-02BPLCRACK/CHASSIS/115/230PANASONICACSERVOMOTOR***152D1C1.5KWNSDV8L45-11NSPPV8L4511TEXASINSTRUMENTSPLC500-7201USPP5007201ASEABROWNBOVERI3BSE004939R1NSPP3BSE004939R1TEXASINSTRUMENTS5TI-1034-2SEQUENCERMODULE***XLNT***FOXBORO280H-SBBA-TSA-GUSPP280HSBBATSAGMODICONAS-P890-000NSFPASP890000PanasonicACServoDriverMDDA153A1A1.5kWPanasonicACServoMotorMHMD022G1UNIBFreeShipTEXASINSTRUMENTS545-1101TI545CPUMODULE5451101MODICON140-CPU-113-03USPP140CPU11303BOSCHB830-303074NSPPB830303074NSDV8L45-11NSPPV8L4511SABROE1572.008NSPP1572008PanasonicACServoDriverMSD021A1XX34FreeShipASEABROWNBOVERI3HAA3563-AHA/2USPP3HAA3563AHA2ASEABROWNBOVERIACS800-U1-0006-5-L502-L503-N660USPPACS800U100065L52TEXASINSTRUMENTSPLC555-1105USPP5551105TEXASINSTRUMENTSPLCMTUSPPMTOMRONAMD-SL1AC100/110USPPAMDSL1AC100110ALLENBRADLEY196258USPP196258PERCEPTRON911-0004USPP9110004ASEABROWNBOVERIAF400-30-11-70NSPPAF400301170ALLENBRADLEY1333-BAAUSPP1333BAAPanasonicServoDriveMADR04311ANewinBoxFreeShipSiemensTI530C-1104PLCController530C-1104MODICONP2-984A-816USPPP2984A816PanasonicACServoMotor***102A1GFreeShipASEABROWNBOVERIACS601-0006-4-000B1500801USPPACS60100064000B3ASEABROWNBOVERIACH401600632-A0AE0000USPPACH401600632A0AESIEMENS6RB2-000-0GB01USPP6RB20000GB01ASEABROWNBOVERIDSPC-171USPPDSPC171ALLENBRADLEY160-BA04SF1-AF-D13-DN2C-DNRC-DNSC1-DSUSPP160BA04SF1AFD13DTEXASINSTRUMENTSPLC5TI-1020-1USPP5TI10201TEXASINSTRUMENTSPLC505-6851USPP5056851ASEABROWNBOVERI3AFE61004955USPP3AFE61004955ASEABROWNBOVERID***C-110NSPPD***C110ASEABROWNBOVERIAF460-30-11USPPAF4603011SANYODENKIPU0A015-EM61P00USPPPU0A015EM61P00ASEABROWNBOVERI57510001-AA/5USPP57510001AA5TEXASINSTRUMENTSPLC55PL8312000328USPP55PL8312000328TEXASINSTRUMENTS500-5056**TexasInstrumentsRTU84502ModemBoardReturns:NotacceptedASEABROWNBOVERINBRA-658CUSPPNBRA658CASEABROWNBOVERI52603668NSFP52603668NEWSEALTISiemens575-21045752104VMEPLCCPUMITSUBISHIA1-71SHCPUUSPPA171SHCPUPanasonicMSDA041D1A37ServoDriveFreeShipGEFANUCIC640MWS901USPPIC640MWS901TEXASINSTRUMENTSPLC7MT-200USPP7MT200TEXASINSTRUMENTSPLC500-5010NSFP5005010TEXASINSTRUMENTSPLC500-5020NSFP5005020ASEABROWNBOVERI3BSE018283R1NSFP3BSE018283R1PanasonicACServoDriverDriverMUDS023A1MNewinBoxFreeShip***ARCPU-700-AUSPPCPU700APanasonicMSD5A1P1EACServoDriverTEXASINSTRUMENTSPLC6MT2456213USPP6MT2456213GEFANUC44A297062-G01USPP44A297062G01)
