1747-R51747-R5限时控制:继电控制逻辑利用时间继电器的滞后动作进行限时控制。时间继电器一般分为空气阻尼式、电磁式、半导体式等,其定时精度不高,定时时间易受环境湿度和温度变化的影响,调整时间困难。有些特殊的时间继电器结构复杂,不便维护。PLC使用半导体集成电路作定时器,时基脉冲由晶体振荡器产生,精度相当高,定时范围一般从0.1s到若干分钟甚至更长,用户可根据需要在程序中设定定时值,然后由软件和硬件计数器来控制定时时间,定时精度小于10ms且定时时间不受环境的影响。设计与施工:使用继电控制逻辑完成一项控制工程,其设计、施工、调试必须依次进行,周期长,而且修改困难。工程越大,这一点就越突出。而用PLC完成一项控制工程,在系统设计完成以后,现场施工和控制逻辑的设计(包括梯形图和程序设计)可以同时进行,周期短,且调试和修改都很方便。可靠性和可维护性:继电控制逻辑使用了大量的机械触点,连线也多。触点开闭时会受到电弧的损坏,并有机械磨损,寿命短,因此可靠性和可维护性差。而PLC采用微电子技术,大量的开关动作由无触点的半导体电路来完成,它体积小、寿命长、可靠性高。PLC还配备有自检和监督功能,能检查出自身的故障,并随时显示给操作人员,还能动态地监视控制程序的执行情况,为现场调试和维护提供了方便。在电机功率很小时,有时候电机的空载电流将超过电机额定电流的50%,而对于大功率的电机,其空载电流还可能不到电机额定电流的20%,同步电机更低。同时电机极对数越多空载电流越大。FuZhouZhuoKaiElectricCo.,Ltd.公司简称:卓凯电子公司地址:福州市台江区***街万达广场二期A2#写字楼11层12室公司聯络人:李工(销售工程师)Tel:0591-62182520Fax:0591-62032566Phone:13696852881商务***:1273632994————————————————————————140GH15C3C20871TMDF1NN12C2800TKD2AAAA800T-FXTQ20GA145MLAFT0900P3793012SE2350ITE800TH3342A440KT11367TA7291756L71S1492I***0D240A2800TJ2KC7BCAX800HN100Y190SBND2CB40C800T3PZ845T-DZ33BEHW38O5147615802TW7B440TMDALE10NEPE800T-2JGH2KB7FX800TJ4610KR7800TE1570A280PWRM22BM4871TMDH4CP12N4800T-3TZM11440FM0320DYNN800TQ***24RGGR802CNL22ENX9800T24JG18KB7AX140MGH8PC30O52862931HP2A2NOP800FM-L***33Z32102800TFXJT4A5854K20GL7872CNH8NN12P3871TMN40NN30A2140UH6C3C35A836TT251JX24X151485PSP8R5C2M5800TJ41441771IL800TCB2A875CPNM30CN34D4871TMDH5CE18D4700HTF12300SU24800H2HX7PM1SKH1FOABD1440PMDPS11BMPLB310PHJ72AA800HNR3KM4800HFRXNP16R1485CP2N5C509BOB440TMDBLE15IBJB800T-J7303KA7B800HDPB22AAXX57800TQ***24RAAG1746IV32800HSRB00XX800TFXMPH16RA800TJ44KU7H875C-F10C30-R3855TPB24Y3Y6Y5Y4A12090KPBM412AAO5532543GTFAS25SL240836TT351JX26X22X15440TAKEYE10BM800TH3210A4440FEHATT0030043GTTBB25FL18086466-92SC440TMDALE10CCGGMPMA2152FSJ74AA889RF3AEA109810PC8MMOEMA1102CCOD931494VDR606440TMDBLE170I0K440TMDCLE10LHPH440TMSALE10HR855BM***M800HW220Y-2006-1-H00AASCHNEIDER(施耐德)140CPU6716051FBM201ALSPA变频器控制板ENU00/03/AJ-MHM10TSXSAY100R电源ABBAO6102Allen-Bradley-831746-A13AW83977ATF-AWWinbond2711-B5A9L1140DAO85300Honeywell621-6550849AZOD24AB849AZOD24802TA1TPAB802TA1TPOMRONE2EG-X5MC2-M1NSFPE2EGX5MC2M11756-L55M12?160-AA04NSF1P1AllenBradley160AA04NSF1P1N70YASKAWA安川伺服电机SGMAH-08AAF41安川YASKAWA伺服驱动器SGDH-1AAE发射机875ec-b2f-ac个3HAC3473-1HG5700ZCRKCH-***-J-141-D*AB6ES5511-5AA14或6ES5511-5AA14板卡A90L-0001-0515/R欧姆龙触摸屏NT631C-ST151B-***6ES5955-3LC13SIEMENSPTM6.2U10带底座A860-2109-T302GE469-P5-HI-A20-E1A06B-6079-H104OMRONE2E-X10MY1-NNSFPE2EX10MY1NJANCD-JIF10MBI/MNI(16413-15)XVME601/5TSXCANKCDF90TE501823880AC-motorSST-PFB-CLXModiconTSXCompactPC-A984-1451746-NO4V140ACI04000Bendix3730409?????1336F-BRF200-AA-ITXPCWHT-L1-4B0-Q2CREELTDABAB6171-SFB3HeidenhainTS649SK40147KJ3003X1-EA112P0921X022SERINTTERMBLOCK1XREWHTL10000X0901CRENice1756-ON8W/TerminalABControlLogix1756-0N8ELMASONICMF-4000NACHIPSUA60BJANCD-CP50BJAMSC-C8120YASKAWA安川伺服电机SGMSH-20ACA61PC-K984-785IMTECACCULINE990001703140XTS002001746-RL53ABMicroLogix10001761-L16BWAAS-P120-0001336F-C075-AN-DEAllen-Bradley140-MN-0016MotStarterUSAFED-13-FA2KEWESTINGHOUSE2D81400G11安川驱动器SG0L-01AP,安川变频器配,安川伺服配TU847IBSST24BKM-TKl?cknerMoellerEMA-101-DD2SPS-Steuerung-used-V4550220-01003HNM08291-13HNA008129-001CLAMPRINGTU811V1IC200CPUE051756-IF16SNAP-AITM-2Allen-BradleySLC500ProcessorUnit,1747-L542,SERB,V31336F-CWF10-AA-EN16101-174/10?39SDM024DCCBN?IC754VBI08CTD?140PLC140CPU11303FANUCA16B-2200-0842*NEW*)
