1794-OB8EPXT1794-OB8EPXT1794-OB8EPXT用户可以选用不同档次的CPU模块、品种繁多的I/O模块和特殊功能块，对硬件配置的选择余地较大，维修时更换模块也很方便。3.CPU模块中的存储器存储器分为系统程序存储器和用户程序存储器，系统程序相当于个人计算机中的操作系统，它使PLC具有基本的智能，能完成PLC设计者的规定的各种工作。系统程序由PLC的生厂家设计并固定化在ROM（只读存储器）中，用户不能读取。用户程序由用户设计，它使PLC能完成用户要球的特定功能，用户程序存储器的容量以字节（B）为单位。（1）.随机存取存储器（RAM）用户可以用编程装置读出RAM中的内容，也可以将用户程序写入RAM，因此RAM又叫读/写存储器。RAM的工作速度高、价格便宜、改写方便。（2）.只读存储器（ROM）ROM的内容只能读出，不能写入。（3）.可以电檫出可编程的只读存储器（EEPROM）S7-200用EEPROM来存储用户程序和长期保存的重要数据。【***】【诚信】【创新】【合作】【共赢】厦门泰尼电气有限公司【产品质量】原装进口***【检测标准】按原厂标准【产品质保】1年【快递时间】24小时到【联系我们】＆业务经理：小黄＆洽谈电话：0592-6809319/18950191386＆商务***：2917675397＆传真（FAX)：0592-6890859（请注明，01006收）＆公司全称：厦门泰尼电气有限公司＆公司地址：厦门市海沧区海沧街道滨湖一里1号楼TUBETEX010385MDLX010385330RPM1/2"SHAFTAIRPNEUMWESTINGHOUSECIRCUITBREAKERHNC31200F600VAC1200A12BALDORDCTACHOMETERXPYP601A101-250V/1000RPMHEIDWNHAINDR.JOHANNESDIGITALREADOUTDISPLAYOPERATOABBM7-4M74120VAC/125VDC180VAMOTOROPERATORaccutracnorthamericanelectroactuatorh5530g-2b-09dNOSNONAME22-1/4IMPELLERCENTRIFUGALFANBLOWERRELIANCEELECTRICPMIPROCESSORPLCMODULECARD0-60000AMICONTYPACTDCDRIVECONTROLLERTPy3A-0322A-7.5HPTPyGEGENERALELECTRICCIRCUITBOARDAXIS2D44A399739-G01CONEDRIVESPEEDREDUCERGEARBOXSHV40-Y8A15:1RATIO1SUPERIOR&ELECTRICSESLO-SYN2000MX2POWERSUPPLYMOPaxtonSuperchargerCentrifugalBlowerHead56180SQUAREDCIRCUITBREAKER250A250AMP3P3POLES3600VCLARKCONTROLSA65-420654-3A654206543A65420654FEFANEQUIPMENT3/8-26HIPRESSURECENTRIFUGALBLOWERSIEMENSCENTRALPROCESSINGUNITCPUMODULE6ES7313-6CEWESTINGHOUSEPANELBOARD600A600AAMP480VHU04550FDPDANFOSSVLT5000ACDRIVEVLT-5027460V25HP25HPGouldRemoteI/OProcessoras-J892-002asJ892002J892EUROTHERMDRIVESMOTORCONTROLDCDRIVE40HP40HP29KWALLENBRADLEY1336SPIDERSERVOACDRIVE9.9A1336Z-SB0TANDLERGEARBOXSPEEDREDUCERD1-ZA52832528321:1RATITBWOODSWOOD'SE-TRACACDRIVEINVERTER3HP3HP460VBOSCHPSVPSSF15ERM565928763HYDRAULICPUMPLIGHTNINV5P18VEKTORchemicalagitatormixer.25HP2SQUARED112T3H112.5KVA112.5KVATRANSFORMERHIVOLTACCUTRAC/NORTHAMERICANACTUATORH4523-027-20H5530ABBACS600ACS600-DEMODRIVEDRIVE1.4A3AUA489002B4153GE9123B3875112.5KVA112.5KVATRANSFORMER3PHHI480VVICKERSHYDRAULIC45VTBS60A2203AA22R02-125605-1BBCBROWNBOVERIELECTRICPOWERSHIELD505TESTSETENCO130-506148"4'FINGERBRAKE16GA16GAUGEMETALBIngersollRandIntelliDrive131***8450.4kVA50.4kVARexrothControllerAxisVT-HNC100-1-22/W-08-I-0VTHNC10INDRAMATACSERVOPOWERSUPPLYTVD01.2-15-03TVD012-15-AEAGENERALIMPIANTIHIGHVOLTAGETESTERCONTROLCONTROALLENBRADLEY500FL-EOD93STARTER500FL-E0D93.SERA12MoorePCBoardAPACS15825-32-2-BDD15484-111-115825-4OMRONIDMYASKAWAACDRIVEP5+106A96ACIMR-P5U404540TEXASINSTRUMENTSSERIES500CONTROLLERCONTROLPLCMODINDRAMATACSERVOCONTROLLERDRIVEDDS02.1-A200-DDDS0SKF71928ACD/P4ATBTCW05Z*-3SUPERPRECISIONROLLERBESYLVANIATMSTARTERSIZESZ5T13UO35T13U035270AMPSIEMENSTRANSFORMER4AM6142-8DD40-0FA01.6KVA/7.3KVAHIAllenBradleyPanelView6002711P-K6C20DSeriesARevAHUBCITYREDUCERGEARBOX26060220-67928RATIO1000:1CappUSACircularChartRecorder412043CR331554EUROTHERMDRIVEMOTORCONTROL46A46AMPA584S/0220/40NOSDEUBLIN6300-077-157Q0743"NPTROTARYUNIONVGEBuswaySwitch3Ph3Ph200A200AmpAFVK424R4WGE5CD154HA812B8017.5HP7.5HPDCEUROTHERMMOTOR1150AmiconTypact5HP5HPDriveTPY2-421A-5HP25AAmp180MAGNECORPMAGNECLUTCH100MCW-90-B-200751016MAGNETICHALDEX1300322HYDRAULICFLOWDIVIDER1"NPT3/8"NISOCHEMPULSAFEEDERCMH1-ASNMLYSSSTAINLESSS/SPUMP1.TECOMAX-SEN010410HP10HPELECTRICMOTOR230/460NOSCONEDRIVESHV40-Y8AGEARBOXSPEEDREDUCER60:1GE5CD164MA067A80125HP25HPDCELECTRICMOTOR240V24GEMICROVERSATRIPTRIPUNIT1600A3000AC330LITR16B)
