1791-8AC模块1791-8AC模块1791-8AC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。TEXASINSTRUMENTSPLC500-5194USPP5005194ASEABROWNBOVERI57310255-AXUSPP57310255AXPanasonicACServoMotorM***D022PJANewPerceptronDigital917-4010DigitalSurfaceSensorTEXASINSTRUMENTSPLC500-5024USPP5005024ASEABROWNBOVERI3ADT306200R1NSPP3ADT306200R1PanasonicServoDriverMCDHT3520ENewinBoxFreeShipCUTLERHAMMER0065006-006359​8-003NSPP00650060063598​00NewPerceptronEncoderCableModule515-0076#29448TexasInstruments5TI-5500KTRON0671-30022USPP067130022PERCEPTRONPCICOMMUNICATI***BOARD500-0243TexasInstruments2461553-0001ASEABROWNBOVERIOETL-NF1600SWUSPPOETLNF1600SWTEXASINSTRUMENTSPLC505-4332NSFP5054332TexasInstruments(Siemens)TI-435PLCw/RackModulesAPICONTROLSPS-3306I-E-C10​4NSPPPS3306IEC104SIEMENS1HU3104-0AD01-​ZUSPP1HU31040AD01ZTEXASINSTRUMENTSPLC500-5840NSFP5005840TEXASINSTRUMENTSPLC435-DC-CPUNSPP435D***UTEXASINSTRUMENTSPLC305-DC-04BNSFP305DC04BSIEMENS6FX1-120-2CA00USPP6FX11202CA00PERCEPTRON912-0007PANASONICACSERVOMOTORMQMA011A2BPanasonicMSDA041D1A37ServoDriveFreeShipREIS101122USPP101122SIMPLEXGRINNEL​L2850-9004NSPP28509004ACSERVODRIVERPANASONICMSD011A1XFreeShippingTEXASINSTRUMENTSPLC46198-2USPP461982ASEABROWNBOVERIFDC86-UNIT1BNSPPFDC86UNIT1BNATIONALINSTRUMENTNI-CFP-2020NSFPNICFP2020PANASONICSERVODRIVER/ADKA100​BPTADZ/AMKA080​810KAE/NEWTEXASINSTRUMENTSPLC500-2151AUSPP5002151ASIEMENSTIPLCXM22401LMOTORINTERFACEMODULEL00OSIEMENS6ES5-312-5AA31USPP6ES53125AA31CEGELECMLOUSPPMLOASEABROWNBOVERIMFE50034180100​4EHNSPPMFE50034180100​4EALLENBRADLEY1336F-BRF30-AA​-ENUSPP1336FBRF30AAENOMRONF150-SLC20USPPF150SLC20OnePanasonicServoDriverMADDT1207FreeShipWorldwideASEABROWNBOVERIACS601-0060-4-​000B1200801USPPACS60100604000​B2OLECLT1USPPLT1TexasInstruments500-5020ASEABROWNBOVERI064851-001NSFP064851001TITEXASINSTRUMENTS530-1104CONTROLLERPLCMODULETEXASINSTRUMENTSPLCRTU-8635-SSDNSFPRTU8635SSDASEABROWNBOVERIUSART86-8CHNSFPUSART868CHTEXASINSTRUMENTSPLC565-2120USPP5652120ALLENBRADLEY7300-UMG-1USPP7300UMG1MEASUREX05353500NSPP05353500ALLENBRADLEY1336-C007-EADUSPP1336C007EADSICKOPTICELECTRONICFGSE-900-23NSPPFGSE90023PanasonicACServoMotorMHMD042G1UNIBFreeShipPANASONICACSERVODRIVERADKA100GVTAAACNCPanasonicM***022A1BACServoMotorFreeShipTEXASINSTRUMENTSPLC315-DDUSPP315DDALLENBRADLEY813S-VOAUSPP813SVOAATLASCOPCO2101-S7-1USPP2101S71ASEABROWNBOVERISPR-SK19591-7NSPPSPRSK195917TEXASINSTRUMENTSPLC565-2120NSPP5652120PerceptronFrameGrabberBoard495-0191#29402YASKAWAELECTRICCACR-SR10BY1SS​Y9USPPCACRSR10BY1SSY​9MODICON140-ACI-030-00FNFP140ACI03000)
