1746-P21746-P21746-P2虽然工业控制机和可编程控制器本身都具有很高的可靠性，但如果输入给PLC的开关量信号出现错误，模拟量信号出现较大偏差，PLC输出口控制的执行机构没有按要求动作，这些都可能使控制过程出错，造成无法挽回的经济损失。影响现场输入给PLC信号出错的主要原因有：1)造成传输信号线短路或断路（由于机械拉扯，线路自身老化，特别是鼠害），当传输信号线出故障时，现场信号无法传送给PLC，造成控制出错；2)机械触点抖动，现场触点虽然只闭合一次，PLC却认为闭合了多次，虽然硬件加了滤波电路，软件增加微分指令，但由于PLC扫描周期太短，仍可能在计数、累加、移位等指令中出错，出现错误控制结果；3)现场变送器，机械开关自身出故障，如触点接触不良，变送器反映现场非电量偏差较大或不能正常工作等，这些故障同样会使控制系统不能正常工作。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————SIEMENSCONTROLBOARD6SC6100-0GA11/REPAIRED6SC6100-OGA11FLEXLINKFLEXLINKDRIVEUNITZUSX85DRIVE004XBEB4A85HRAGPDOVERINSTRUMENTSAMPLIFIERBOARD***A6520***A6520HS-50-001D16520-5002GA6520-12BALDORDCMOTORCDP36043.0HP180V14AMP1750RPMFR184CSPEC36P149Z507EATONVICKERSPUMPOLF15VNV15BMW02SBRJFZP-1/3.1/PBOSCHREXROTHDIGITALCONTROLLERDMX-1X4WRSE10VINBOXGEFANUCDS3800NFCD1K1EFIRINGCIRCUITCARD305680/REPAIREDBYGENACHIACSERVOMOTORMFMA452D6V34.5KWINBOXPARKERORIGAOSP-E0SP-ELINEARDRIVE2MBHDIISIZE25R20K10000000-02000YOKOGAWABATCHSETSTATIONSLCC/201-E/MTSSLCC-201*E/MTSNIBSLCC201MODICONPLCTSXTSXP574823AMETYPORTPV:01RL:00BOSCHPOWERSUPPLYLTL00-3/9NV20/1F-DD-64711DSPACEDS2103MULTI-CHANNELD/ABOARDDS2103-02SN73545FANUCA16B-2201-0080REFURBISHEDBOSCHDIGITALDRIVECONTROLLERDM15K1101-DBOSCHDIGITALDRIVECONTROLLERSERVODYNDM008K1101-DBOSCHDIGITALDRIVECONTROLLERSERVODYNDM30K1101-DOKUMASERVOMOTORBLMOTORBL-MC300J-20SNANOENCODERELEKTROMATENELEKTROMATSAFEDRIVESHUTTERDOORMOTORSG85SI40.28BENTLYNEVADA3300/55-01-04-03-03-00-00-06-00DUALVELOCITYMONITOREMERSON320ACHASSISP/N858905-00REVA1STEPPERNIBEMERSONSERVOMOTORDXM-208CBDXM208C0.47HP230V3.0AMP5000RPMREVA2MITSUBISHIMELSECANALOGINPUTMODULEA60MXRDETTRONICSDETTRONICSUV/IRFLAMEDETECTORU7652U7652B100124VDCDRIVECONXTSERIESXTD4022-00020HP/11KW380-4603PHSOFTWAREPRO1V050METSOVALMETESUBOARDA413370422138-3AHILGERKERNPUMP1-1,2-EE-R-F-100/HK-0/GL-Sp/SBNRZADA1001018FANUCA20B-1000-0180/09AA20B1000018009AHUBCITY0220-54006-07900220-54006MODEL7903.78/1RATIOSTDREBUILTBEVELPARKERPNEUMATICCYLINDER8INBORE40INSTROKE250PSISIEMENSSIMODRIVE6SC6120-0FE01/REPAIREDELECTRO-CRAFTBRU-500POWERSUPPLYP***-509101-0112FALLEN-BRADLEYULTRA5000SERVODRIVE2098-IPD-020A9111-0064V1.102098IPD020RBANNISCOMPANYINDUSTRIALPROBEDEMAGNETIZER22AMPSN10-D-50REXROTHVARIABLEVOLUMEVANEPUMPSVPSVPSAF15ERM66HYRADRAULICR978709514SUDMOSANITARYDOUBLESEATVALVESTAINLESSSTEEL6"DN6"-SCH5PN102003513GEATUCHENHAGENDOUBLESEATVALVESTAINLESSSTEEL6"REN-IPS6"-IZFANUCACSERVOMOTORA06B-0502-B074#7076REBUILTCONEDRIVESPEEDREDUCERGEARBOX6:1HU35-1HU35A060-11750INPUT300RPMOUTGEPANAMETRICSISMISSUBASSEMBLY703-1141710-1141REVE800GFXMGEFANUCDS3800NHVN1A1AHIGHVOLTAGECARDREFURBISHEDBYGESHINKOACSERVODRIVESDD-F-280DC750W-3-2NOTINBOXGEFANUCA6B-3200-0260/3CNOBOXGEFANUCDS3800DS3800NMEADS3800NMEA1P1JABBCPUBOARDDCS500SDCS-CON-1REVLPR:ESER#440194DeZURICKBAW206203R001SIZE12PSI100COPES-VULCANSWITCHSEH90DOPAGDISPENSINGVALVE401.05.51BL.21508401.05.650.15195GEFANUCOPERATORINTERFACE18-MA02B-0120-C051MARFANUCA16B-1210-0090/03AA16B1210009003AINOPENEDFANUCPACKAGEALLENBRADLEYMPL-B230P-EJ44AAMPLB230PEJ44AAKINETIXSERVOENDRESSHAUSERTURBIMAXSOLIDSCONTENTSENSORCUS41A290DEGREESCATTEREDLIGHTABBMODULEBOARDDSDP170DSDP170)
