1794-IE81794-IE81794-IE8系统接地：PLC控制器为了与所控的各个设备同电位而接地，叫系统接地。接地电阻值不得大于4Ω，一般需将PLC设备系统地和控制柜内开关电源负端接在一起，作为控制系统地。信号与屏蔽接地：一般要求信号线必须要有惟一的参考地即“单点接地”，屏蔽电缆遇到有可能产生传导干扰的场合，也要在就地或者控制室***接地，防止形成“地环路”。信号源接地时，屏蔽层应在信号侧接地；不接地时，应在PLC侧接地；信号线中间有接头时，屏蔽层应牢固连接并进行绝缘处理，一定要避免多点接地；多个测点信号的屏蔽双绞线与多芯对绞总屏蔽电缆连接时，各屏蔽层应相互连接好，并经绝缘处理，选择适当的接地处单点接点。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！！！————————————————————————————————ALLENBRADLEY1336-B010-EAD-L3HALMARROBICONRF3PCI-48-415KVA-12%CONTROLPANELYAMADANDP-25BSTINABOXFANUCA16B-3200-0260/12CTELEMECANIQUETSXCCM100ESIEMENS6FX1120-5BB01PCBOARDGECIRCUITBOARD44B398293-001/44A394699-G03RELIANCE2GU41003ACDRIVEEMERSON960114-01POSITIONINGSERVODRIVEPCM-16RELIANCEELECTRICPCBOARDRELAYCARD0-54374ALLENBRADLEY1336S-CWF20-AN-FR4RELIANCEELECTRIC1326AB-B430E-21-LCINCINNATIINCORPORATED829808HONEYWELLELECTROPLEBS1AADLTGEFANUCIC600CB536LCOMMUNICATI***CONTROLMODULERANSBURGPOWERSUPPLY74306-02DANFOSSVLT3004VARIABLESPEEDDRIVE175H1737FANUCA16B-2100-0080ALLENBRADLEY20AE011A0AYNNNNNSERIESAFANUCA61L-0001-0093CRTDISPLAYMODULED9MM-11BACCU-SORTSYSTEMPEBOX-SB/CSPACIFICSCIENTIFICBRUSHLESSSERVOMOTORR43HENA-R2-NS-...LINXXYMARKLASERPRINTERCONTROLBOARD0632-706-00USGECIRCUITBREAKERSFPA36AT0250GEFANUCIC697CMM711PCOMMUNICATI***PROCESSOROUTALLENBRADLEY1336T-C007-AN-GTOROSEMOUNT3051CD1A22A1AB4S2OUTOFABOXALLENBRADLEY20BE9P0A0AYNAND0POWERFLEX700RELIANCEELECTRIC14C303FLEXPAKPLUS20HPBAILEYBUSINTERFACEMODULENBIM02DYNAMATICNEGATIVEBASEDRIVER15-591-8FANUCUNITMODULEA05B-2452-***73ALLENBRADLEYSERVOMOTOR1326AB-B720E-21ALLENBRADLEY22C-D045A103SERIESAROSEMOUNT3050CD2A22A1AM5GEFANUCIC660BBS102PISOLATEDBLOCK115VAC/125VDCFACALLENBRADLEY1747-L553SERIESAW/KEYCPUMODULEUSEVALCONVWX150CIKN115ACINABOXSICKLUT3-920TECHMOTIVE***700A01V217CONTROLLERGEFANUCTHERMOCOUPLEBLOCKINPUTMODULEIC660BBA103RC...CUTLER-HAMMERHMCP050K2SGEFANUCIC600YB827CCOUNTERMODULEGEFANUCIC693APU302NPOSITIONMODULENO***ON171031CYASKAWAUSAREM-07CSL2KBROSEMOUNT8711TE020R1N0MAGNETICFLOWTUBEOUTOFHONEYWELLDR4302-0000-G0100-0000-0000-00-000-E0OMOORE352PEA21VNNNNA4/MX033898004HONEYWELLSTG90L-E1G-00000-AN,ZS,-X+XXXXOUTOFASICKFGSE-1050-111PARKERCEET00-104-10PCBET00101DRIVERBOARDINSEMMT30U4-36MOTORMITSUBISHIFR-A540-11K-NAFANUCA16B-2200-0090/05AFANUCA16B-2200-0090/09AFANUCA16B-2200-0390/09B)
