1769-ARM输入模块1769-ARM输入模块PLC的容量选择PLC的容量包括I／O点数和用户存储容量两个方面。1．I／O点数PLC的I／O点的价格还比较高，因此应该合理选用PLC的I／O点的数量，在满足控制要求的前提下力争使用I／O点***少，但必须留有一定的备用量。通常I／O点数是根据被控对象的输入、输出信号的实际需要，再加上10％－15％的备用量来确定。2．用户存储容量用户存储容量是指PLC用于存储用户程序的存储器容量。需要的用户存储容量的大小由用户程序的长短决定。一般可按下式估算，再按实际需要留适当的余量（20％－30％）来选择。存储容量=开关量I／O点总数X10十模拟量通道数X100绝大部分PLC均能满足上式要求。应当要注意的是：当控制系统较复杂。数据处理量较大时，可能会出现存储容量不够的问题，这时应特殊对待。ALLENBRADLEY1771-TCMNSFP1771TCMTEXASINSTRUMENTSPLC505-2595USPP5052595ASEABROWNBOVERI57520001-BZ/5USPP57520001BZ5FANUCA05B-2351-02NSPPA05B235102TEXASINSTRUMENTSPLCMP6000USPPMP6000TEXASINSTRUMENTSPLC500-5840NSFP5005840TEXASINSTRUMENTSPLC7MT-400NSFP7MT400TEXASINSTRUMENTSPLC505-7101USPP5057101EXTRON60-107-01USPP6010701ASEABROWNBOVERI3GVA072002-CSDNSFP3GVA072002CSDASEABROWNBOVERIACS601-0100-4-​000B1200801USPPACS60101004000​B1ALLENBRADLEY1326-CFUT-150NSFP1326CFUT150ASEABROWNBOVERI3HAA0001-JCNSPP3HAA0001JCOMRONF3S-A321-LUSPPF3SA321LPanasonicACServoDriverMADDT1205003NIBFreeShipASPECT68040UNSPP68040UTEXASINSTRUMENTSPLC500-5030USPP5005030TEXASINSTRUMENTSPLC500-2103USPP5002103TEXASINSTRUMENTSPLC575-2105USPP5752105TEXASINSTRUMENTSPLC500-5013NSPP5005013TEXASINSTRUMENTS500-5037-A**MITSUBISHIMP-SOP500USPPMPSOP500Panasonic2.0kWACServoMotorM***A202D1D(freeshipping)TEXASINSTRUMENTSPLC500-5828AUSPP5005828AMKSINSTRUMENTSE28BU5TBF1BUSPPE28BU5TBF1BTEXASINSTRUMENTSPLC500-5012NSFP5005012GENERALELECTRICDS3800HXPA1B1AUSPPDS3800HXPA1B1ATEXASINSTRUMENTSPLC575-4332NSFP5754332SAJF//PANASONICMUMA042P1SACSERVOMOTORUSEDTRANSDUCERTECHNIQUESPLCLOADCELLTIO-3000TI0-3000TI-3000ALLENBRADLEY150-A54NBUSPP150A54NBTEXASINSTRUMENTSPLC500-5047AUSPP5005047ATEXASINSTRUMENTSPLC505-ATM-4120USPP505ATM4120ASEABROWNBOVERIDSCA-114USPPDSCA114TEXASINSTRUMENTS500-5056**OnePanasonicM***5AZP1BACServoMotorFreeShipPanasonicACServoDriverMSD013A1XXFreeShip505-4832TexasInstruments/Si​emensTI5054832R25TEXASINSTRUMENTS505-6208BUSPP5056208BALCATEL210SDMLAMNSFP210SDMLAMGEFANUCIC3600SBMA1USPPIC3600SBMA1TEXASINSTRUMENTSPLC405-6MTNSPP4056MTGEFANUCIC600LX612NSFPIC600LX612GUTICOR76584-32USPP7658432SEWEURODRIVET4616.0USPPT46160SIEMENS1HU3058-0AC01USPP1HU30580AC01ASEABROWNBOVERIEH550G-PRL11NSFPEH550GPRL11RELIANCEELECTRICS-12011-1TUSPPS120111TPanasonicACServoDriverMSD021A1X04FreeShipOnePanasonicServoDriverMADDT1207+OneMotorM***D022S1TFreeShipWorldwideSQUAREDMA36800USPPMA36800SIEMENS6ES5-701-3LA12NSFP6ES57013LA12PERCEPTRONCAMERATRICAMSURFACESENSOR912-0007PanasonicACServoDriverMDD083A1VVFreeShipPanasonicMSD153A1VACServoDriverPANASONICMINASACSERVODRIVERDV88003LFGAEAJL100VTEXASINSTRUMENTS520C-1102**PanasonicACServoMotorM***082A4BFreeShipPROFACEGP577R-T1-24​VPNSPPGP577RT124VPTexasInstruments500-5031JTEXASINSTRUMENTSPLC500-4010USPP5004010TEXASINSTRUMENTSPLC505-7101NSFP5057101TEXASINSTRUMENTSPLC505-6108ANSFP5056108AALLENBRADLEY2711-K6C10L1USPP2711K6C10L1TexasInstrumentsCUSTOMPIDMODULEELECTROCRAFT9101-2161USPP91012161SIEMENS6ES5-475-5AA11NSFP6ES54755AA11TEXASINSTRUMENTSPLC510-2101USPP5102101RELIANCEELECTRIC45C-409NSFP4509TEXASINSTRUMENTSPLC2497435USPP2497435TexasInstruments500-2112PanasonicACServoMotorM***021A1AXw/60daywarranty)
