1770-CD2输入模块1770-CD2输入模块1770-CD2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。BRINKMANNTL144S250NSPPTL144S250TEXASINSTRUMENTS500-50355005035TEXASINSTRUMENTSPLC505-ATM-0440USPP505ATM0440APICONTROLSPS-3306I-E-C104NSPPPS3306IEC104PanasonicACServoMQDB012AAD100W&MotorMQMA012A3FASEABROWNBOVERIDSQC-211NSPPDSQC211TEXASINSTRUMENTSPLC545-1103NSFP5451103ASEABROWNBOVERI57275758NSFP57275758TEXASINSTRUMENTSPLC530C-1108USPP530C1108OnePanasonicACServoDriverM***A015A1AFreeShipSIEMENS6ES5-943-7UA11USPP6ES59437UA11ASEABROWNBOVERIEH300C-1LNSFPEH300C1LPanasonicMSD021A1XXACservodriverTEXASINSTRUMENTSPLC961642USPP961642PanasonicACServoDriverDriverMSD043A1XXVFreeShipExpeditedshippingailableMOOG152D423USPP152D423KOLLMORGENINDBDS5A-206NSPPBDS5A206GALILMOTIONCONTROLSDMC-2130USPPDMC2130ASEABROWNBOVERI750191000BNSFP750191000BASEABROWNBOVERI126620-004USPP126620004ASEABROWNBOVERIACS800-U1-0011-5+P901USPPACS800U100115P90PanasonicServoMotor~MFA040LB2NSA~Rebuilt~6MWarrantyPanasonicMSD083A1XGACServoDriverMITSUBISHIHC-H153BS-A42NSFPHCH153BSA42SIEMENSTEXASINSTRUMENTS505-6204ANALOGMODULEXLNTFASTSHIPPINGSQUAREDTVS-2EMA12ANSFPTVS2EMA12AMOTOROLAMVME-147SB-1USPPMVME147SB1XYCOM3300ACTUSPP3300ACTPERCEPTRON911-0011USPP9110011PanasonicACServoMotorMFA092LB2NR920W*NEW*ALLENBRADLEY1772-ME8USPP1772ME8GENERALELECTRIC7VSDD08CD01USPP7VSDD08CD01ASEABROWNBOVERIS4HQ100BRRAS4NSFPS4HQ100BRRAS4TexasInstruments5TI-3201TEXASINSTRUMENTSPLC500-2114AUSPP5002114APanasonicACServoDriverMBDDT2210003FreeShipASEABROWNBOVERISAGS700PANNSFPSAGS700PANPanasonicDV83020LE201ACServoMotorDriverwith60daywarrantyTECHMOTIVETOOL49-4100-00USPP49410000TEXASINSTRUMENTSPLCPWB-2461414-0001USPPPWB24614140001ASEABROWNBOVERI57411490USPP57411490ASEABROWNBOVERI***1006S/B20/0000/22/STDUSPP***1006SB20000022PANASONICACSERVODRIVEADKF50B5AN60W,80WSPECTRUMCONTROLS1756SC-IF8HNSFP1756SCIF8HALLENBRADLEY1326AB-B410G-21-K4USPP1326ABB410G21K4TEXASINSTRUMENTSPLC7MT-700NSFP7MT700HONEYWELL30752783-001USPP30752783001TEXASINSTRUMENTSPLC565-2820NSPP5652820ALLENBRADLEY8520-3APA1USPP85203APA1SIEMENS6SC6-1012A7USPP6SC61012A7ASEABROWNBOVERI57520001-CNUSPP57520001CNASEABROWNBOVERIYM222001NSPPYM222001TEXASINSTRUMENTSPLC500-2101NSFP5002101PanasonicACServoMotorMFA100LB2BSA#5927ASEABROWNBOVERI1912RA001100000STDUSPP1912RA001100000SASEABROWNBOVERI5716075-PUSPP5716075PSIEMENS6ES5-324-3UR11USPP6ES53243UR11ASEABROWNBOVERI57120001-HAUSPP57120001HATEXASINSTRUMENTSPLC6MT-50-2NSFP6MT502GENERALELECTRICDS3800HIOA1C1EUSPPDS3800HIOA1C1EPANASONICAMKB400B20KAHACSERVOMOTORNEWFANUCA06B-0143-B075USPPA06B0143B075)
