1756-TBNH1756-TBNH1756-TBNH在诊断输入／输出故障时，***佳方法是区分究竟是模块自身的问题，还是现场连接上的问题。如果有电源指示器和逻辑指示器，模块故障易于发现。通常，先是更换模块，或测量输入或输出端子板两端电压测量值正确，模块不响应，则应更换模块。若更换后仍无效，则可能是现场连接出问题了。输出设备截止，输出端间电压达到某一预定值，就表明现场连线有误。若输出器受激励，且LED指示器不亮，则应替换模块。如果不能从I／O模块中查出问题，则应检查模块接插件是否接触不良或未对准。***后，检查接插件端子有无断线，模块端子上有无虚焊点。指示诊断LED状态指示器能提供许多关于现场设备、连接和I／O模块的信息。大部分输入／输出模块至少有一个指示器。输入模块常设电源指示器，输出模块则常设一个逻辑指示器。【***】【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BALDORMK5-3358-BLBCEDCSERVOMOTOR120VDC4000RPMGENERALELECTRICRELAYREV.BSECONDSCALIBRATION4DYNAPARENCODERHS20204881437GENERALELECTRIC60AMPADS36060HSSPECTRAFDIFLOWTECHNOLOGYBR30-3-A-4BATTERYPOWEREDRATE/TOTDANIELWOODHEAD61430-MAXHAZARDOUSLOCATI***HANDHELDSCIMATCOCORROSIVELIQUIDSTORAGECABINET2DOOR47"X18ADEPTTRANSFORMERREV.ACATNo.15300-00010MMC-9871-RELIANCE3/4HPDCELECTRICMOTOR90VOLT1750RPMSQUARED250AMPMAG-GARDCIRCUITBREAKERKHP3625029MCARLSONPOWERFLO625CAB-CCB-33782PNEUMATICBRAKECARLSONPOWERFLO625CAB-CCB-36177PNEUMATICBRAKEFISHERCONTROLSPRESSUREREGULATOR1-1/2"95H-118RELIANCE5HPELECTRICMOTOR230/460VAC184TFRAME3PASHCROFTTEMPERATURESWITCH480VAC15AMPS0-100°FROYALPRODUCTSFILTERMISTCOMPLETEFILTERELEMENT2MAGNETEK1HPDCELECTRICMOTOR56CFRAME1750RPMOMRONROTARYPOSITIONERH8PR-16AO***ITH1/2HPDCMOTOR90VDC1725RPM56CFRAMEHAWS7720EYE/FACEWASHSTATIONPEDESTALMOUNTEDINDECCOCABINETUNITHEATER922U05000U5000BTU480VTEMPOSONICS011050050106LINEARDISPLACEMENTTRANSDALLENBRADLEYSLC500PROCESSORUNIT40I/OSERIESB12020:1RATIOGEARREDUCERWILFLEYPUMP1.5X1-6-A7NICE!!LIGHTUSETEXTRONCONEDRIVEGEARREDUCER40:1RATIOMODELMHV35BVERSAVALVEVPP-4302MILLTRONICSHYDRORANGER1CONTROLLERWITH4-20MAISOLAJAMESBURY2-1/2"STAINLESSSTEELBUTTERFLYVALVEW/KILLARKEXPLOSIONPROOFLIGHTINGFIXTUREHZN-61G-HX212PARKERPROGRAMMABLEAIRREGULATING3-WAYVALVE24VDC1RELIANCEELECTRICDCS5000PROCESSORMODULE0-57407-4JPHOENIXCONTACTRAD-I***-900-TX-ACWIRELESSTRAN***ITTERWESTINGHOUSE250AMPENCLOSEDCIRCUITBREAKER175TRIPMACVALVEMANIFOLDASSEMBLY24VDC92B-AAF-CJA-DM-DMB-DCUNO1"INDUSTRIALFILTERHOUSING125PSIGMODELEGARMSTRONG1-1/2"INVERTEDSTEAMTRAPMODELNo.214FOXBOROCHARTDRIVE24HR9DAYWINDM0152KFTECHNOLOGY80COMPUTERDYNAMICS3240BOARDMODULEMAGNETROLF10-4D28-BNBCONTROLFLOWSWITCHMODELVAGE600AMPCIRCUITBREAKERWITH600AMPTRIP600VAC3SIEMENSTD200OPERATORINTERFACEPANEL24VOLTDC1BROOKCROMPTONELECTRICACMOTOR220/230/240V30REGEMSENSORS816031316STAINLESSVISUALLEVELINDICATORNALCOTRASARWATERTREATMENTCHEMICALCONTROLLER6000-0LENZESERVOMOTORMCS-06***1-RS0B0-B11N-ST5S00N-R2SUOPTO22ETHERNETSNAP-B3000-ENETTCP/IPTRANSPORT10BARELIANCEELECTRICTRANSISTERVVIINVERTER602909-68FLOWSERVEB34SPNEUMATICVALVEACTUATORSERIES34VEEDERROOTCOUNTER195326-045HEDLANDFLOW-ALERTFLOWMETERWITHELECTRICALSIGNAPOWERSN011REGULATOR595ST100H-C08DN05ALLENBRADLEY837-V2ATEMPERATURECONTROLLERSQUAREDOPERATINGMAGNETICCOIL800:5AMPC31105-004-)
