1756-DMA31输入模块1756-DMA31输入模块1756-DMA31输入模块常用PLC按容量分类的方法大致可分为“小”、“中”、“大”三种类型。a.小型PLCI/O点总数一般小于或等于256点。其特点是体积小、结构紧凑，整个硬件融为一体，除了开关量I/O以外，还可以连接模拟量I/O以及其他各种特殊功能模块。它能执行包括逻辑运算、计时、计数、算术运算、数据处理和传送、通讯联网以及各种应用指令。如OMRON的C**P/H、***1A系列、***2A系列、CQM系列，SIMENS的S7-200系列。b.中型PLCI/O点总数通常从256点至2048点，内存在8K以下，I/O的处理方式除了采用一般PLC通用的扫描处理方式外，还能采用直接处理方式，即在扫描用户程序的过程中，直接读输入、刷新输出。它能联接各种特殊功能模块，通讯联网功能更强，指令系统更丰富，内存容量更大，扫描速度更快。如OMRON的C200P/H，SIMENS的S7-300系列。c.大型PLC一般I/O点数在2048点以上的称为大型PLC。大型PLC的软、硬件功能极强。具有极强的自诊断功能。通讯联网功能强，有各种通讯联网的模块，可以构成三级通讯网，实现工厂生产管理自动化。如OMRON的C500P/H、C1000P/H，SIMENS的S7-400系列。TEXASINSTRUMENTSPLC575-6663USPP5756663TEXASINSTRUMENTS5TI-20015TIPROGRAMMER*NEW?XYCOMXVME-540NSPPXVME540ALLENBRADLEY837-V1JX15ANSFP837V1JX15AVIDEOJET29900NSFP29900PanasonicACServoDriverMSD043A1XFreeShipYASKAWAELECTRIC***C-2000-2USPP***C20002PanasonicMSD011A1XACServoDriverASEABROWNBOVERI5716075-PUSPP5716075PASEABROWNBOVERIPCS-500FZUSPPPCS500FZBOSTONGEARFWA726-1800-B5​-GUSPPFWA7261800B5GOMRONAMD-SL1AC100/1​10USPPAMDSL1AC100110ASEABROWNBOVERI3HAB2207-1USPP3HAB22071KOLLMORGENINDM-605-B-B3USPPM605BB3Lotof2PanasonicACServoMotorM***A041A1EALLENBRADLEY1326-CPB1-060NSPP1326CPB1060TEXASINSTRUMENTSPLC505-6408NSFP5056408PerceptronDigitalContourSensor916-4079C0400-X0000-Y0​126-Z0287laserALLENBRADLEY8000-MB2NSFP8000MB2SIEMENSTEXASINSTRUMENTSENHANCEDRUNTIMEKEYBOARDCONTROLLER2587716-8002PanasonicACServoDriverMUDS083A1MFreeShipPACIFICSCIENTIFIC6435-017-N-NNSFP6435017NNTEXASINSTRUMENTSPLC500-5053USPP5005053TEXASINSTRUMENTSPLC545-1102USPP5451102ASEABROWNBOVERI57360001-ELUSPP57360001ELPERCEPTRON912-0021USPP9120021PanasonicACServoMotorM***012A1EEFreeShipPANASONICMINASACSERVODRIVERDV88003LFGAEAJL100VALLENBRADLEY2706-B43J31USPP2706B43J31USEDPerceptron390-0049Enna17Monitor0520776002ASEABROWNBOVERIDSQC-236DUSPPDSQC236DSIEMENS6ES7-212-1AA01​-0XB0FNFP6ES72121AA010X​B0MITSUBISHIAJ71QLP21USPPAJ71QLP21TEXASINSTRUMENTSPLC505-2557USPP5052557PanasonicACServoDriveMQDB012AAD02NEW0190-15328TEXASINSTRUMENTSPLC425DC-CPUUSPP425D***UPERCEPTRON911-0015TRICAMCONTOURSENSOR,NIBASEABROWNBOVERIDSQC314BUSPPDSQC314BALLENBRADLEY7300-UMG-1USPP7300UMG1CONTROLOTRON994DN5GS-3NSPP994DN5GS3GEFANUC44A294521-G01USPP44A294521G01USEDPerceptron96KDSPFrameGrabber495-0191RevRTEXASINSTRUMENTSPLC560-2820USPP5602820PanasonicACServoDriveDV451S200#37773ASEABROWNBOVERIS6NH600BWUSPPS6NH600BWTEXASINSTRUMENTSPLC164-2111NSFP1642111ALLENBRADLEY2705-EM11J1USPP2705EM11J1ASEABROWNBOVERIMEM86-192KNSPPMEM86192KTEXASINSTRUMENTS500-5037-AANALOGINPUTMODULENEW5005037APERCEPTRON917-10089171008S0400-X0075-Y0​102-Z0215SURFACESENSORTRICAMTexasInstrumentsRTU-T059-TTERMINATIONPANELASEABROWNBOVERIS4L250EWUSPPS4L250EWTexasInstruments500-5007TexasInstruments5TI-4000TEXASINSTRUMENTSPLC530C-6202NSFP530C6202PanasonicACServoDriverMSDA041A1A/400WTEXASINSTRUMENTSPLC505-4232AUSPP5054232AASEABROWNBOVERIACS601-0016-5-​000B1200800USPPACS60100165000​BATEXASINSTRUMENTSPLC305-01ABNSFP30501ABFANUCA06B-6058-H005USPPA06B6058H005PanasonicACServoM***A152D1C200V3000RPM1.5kW200HzM***A152D1CTEXASINSTRUMENTSPLC560-2128NSPP5602128FUJIELECTRICUG520H-VC1ZUUSPPUG520HVC1ZU)
