BENTLYNEVADA125800-01外部安全电路系统是为了确保整个系统能在安全状态下牢靠工作，避免由于外部电源发作问题、PLC呈现异常、误操作以及误输出形成的严重经济损失和人身伤亡事故，而装置的必要维护电路。①电源过负荷的防护。假如PLC电源发作问题，中缀时间少于10秒，PLC工作不受影响，若电源中缀超越10秒或电源降落超越允许值，则PLC中止工作，一切的输出点均同时断开;当电源恢复时，若RUN输入接通，则操作自动停止。因而，对一些易过负载的输入设备应设置必要的限流维护电路。②严重问题的报警及防护。关于易发作严重事故的场所，为了确保控制系统在严重事故发作时仍牢靠的报警及防护，应将与严重问题有联络的信号经过外电路输出，以使控制系统在安全情况下运转。③急停电路。关于能运用户形成伤害的风险负载，除了控制次第中加以思索之外，还应设计外部紧急停车电路，使得PLC发作问题时，能将惹起伤害的负载电源牢靠切断。④维护电路。正反向运转等可逆操作的控制系统，要设置外部电器互锁维护;往复运转及升降挪动的控制系统，要设置外部限位维护电路。⑤可编程控制器有监视定时器等自检功用，检查出异常时，输出全部关闭。但当可编程控制器CPU问题时就不能控制输出，因而，关于能运用户形成伤害的风险负载，为确保设备在安全状态下运转，需设计外电路加以防护。70908AIC693CPU372FE7C-TC6VGRDSUB311MVI56-PDPMV1JUSP-RA05CU211DI325DO321PS242EE-04053-042DEH11BMDX60A0150-503-04-00MDX61B0011-5A3-04-00140ACI04000140CHS11000140CPS11420140CPU43412A140CRA93100140CRP93100140DDI35300140DDO35300140NOE77101140XBP00600140XBP016006DD1610-0AH06DD1688-0AD0TC-PRR021140CPS11420E1426AE1438DABBRVC8-1/5AAO810V23BSE038415R1SME021336F-BRF100-AE-ENPC-E984-265DPI8803704EMDV60A0022-5A3-4-0T1FK6081-6AF71-1ZZ9-ZS07140CPS11420NTNQ95AAAFC1500MULTI-1140CPS114201336F-BRF100-AE-EN19170FCM10EP0914YM5VPS6ES5-955-7NC12PMV-EP5IRBA06B-6093-H152IRBFTW420-R0G0A1336F-BRF100-AE-ENPM3428PCP10CP40CP40AFTDNBI1756-A101756-ENBT1756-IF6CIS1756-L611756-N21756-PA721756-TBCH1756-TBNHMVI56-MCM140ACI03000140CPU11302140CRA21110140DDI35300140DDO35300600544000DLS61002000DRIVE6RA7025-6DV62-0-Z6RA7081-6DS22-0-ZJWS300-24TRICON3008TRICON4351BTRICON8312205DL240SSN-BG89AC98043-A1045-L31336F-B030-AN-EN1336S-B040-AN-ENPFTL101AYT204001-DT621-6575RC3HAC15639-11769-IQ161769-OW16IMDS011IMFEC12COMPUTERBOARDYPQ-201IC695ALG312UFX71123503E/TRICONEX1756-L62140CPS11420505-6660PCE78/9PS9300-RADES2214-30SLQTACP6201APC810-HAPC810-HMS116-6.3S264-C639200SHDS200DCFBG1BLCDS200LDCCH1ALAIC660BBA0261771-A3B1771-IAD1771-OW161746-IM161746-N04INW-RR85-001IPM0230084351B831221508-02-12-10-0221747-080-01FWA-ECODR3-FGP-02VRS-MS627B.1TBD1BWINBLOCDP-32DI-P-2*16X67AM1323QPJ2D100S2PSGDR-AXA01A1756-CNB1756-L61GWK-AI1161000-010替代型号US2:1161000-010GWK-AI2020164-001替代型号US2:2020164-001GWK-AI2020169-001替代型号US2:2020169-001140CRP81100CACR-SR15BE12G-EATV61HC22N46087010181756-L61MSK061C-0600-NN-M1-UGO-NNNNIK-CU44GOULDTA240LA9-B102NXPP-02CSTUBBEETLB32-1256SE6440-2UD17-5AA11000BASE-LXX250E-24TL3SWITCH1766-L32BWAA1756-CNB/E1757-SRM/B1746-P41785-L30B770-XYC1746-P21746-P41747-L5421770-XYC1785-L30B/EVM3611T57C422B1746-IB321746-N181746-OW161747-L551JWS75-152711P-T10C4D86ES7331-7KF02-0AB06ES7332-5HF00-0AB0A06B-6130-H0021784-PKTXFAS-PCI8000PCL6045BL6AV6545-OBA15-2AXO44DA001IC693MDL753IC693PWR321NFEZQ882335-60001BL450/A(K2-400)MR-SA22MR-SA52TC110XFR600-4140CPS11420140CPS12400RCM470LYLFL1.322SC902-001-0144DA001IC697BEM731IC697BEM733FHA-40C-100-E250HA-675-4-200A86L-0001-0125N860-3117-T010CACR-SR15BB1BFDPS-400ABF3LC12-1F140ACI04000140ARI03010140CRP93200140NOE77101140XBE100001DDN0143BRC400IMASI23INICT13AMZ-15/ECE4809-436-016-DPCI-5565PIORC-110000FC-280SAVMD-420-00-000CKK20-145HC-KFS23HC-SFS5026ES7414-3EM06-0AB0RON905-36000SYS68K/CPU-40B/16-0106087010181203-CN11746-NI16I1746-NI81746-P41747-ASB1747-BSN1747-L5411747-L541C1747-L5421747－L5511747-L5531747-SN1756-CNB1756-CNBR1756-ENBT1756-IB321756-IF161756-IM16I1756-L55M121756-L611756-OF6CI1756-OW16I1756-PA721756-TBCH1784-CF641784-PCIC1784－PKTX1786-TPS1786-XT1794-IB161794-PS31C31129G03/1C31132G011C31224G01/1C31227G011C31234G01/1C31238H015X00070G04/1C31116G045X00119G01/5X00121G01CH-1290140CPS214001179BX12CR14VS364HE693PBM101FIC200GBI001-BFIC200PWR001DIC693MDL231M3AA200MLA6ES5246-4UB21XC5000-400±2X5%/230AK-BX5536AV6647-0AE11-3AX0972-0DP01972-0DP101771-IBD1771-OBD1771-P6S1785-L11BDS200TBQCG1ABBDS200TCTGG1ADS200TBQCG1ABBDS200TCTGG1ANRG05-D240AC-4QA16B-1212-0950IC200CPU002KR-210AUKR-A55MSIC693APU3011747-L532SST-1500-105SDCS-FIS-311179BX12CR14VS364SDCS-FIS-31AKM43G-ACSN2-02SERVOSTAR400-A808PCIPPC5C-AAC-AGBA-BBB-FOSGMPH-01A1A-YR22A-06B-6079-H104TKL4V46101C31129G03/1C31132G011C31224B01/1C31227G011C31234G01/1C31238H015X00070G04/1C31116G045X00119G01/5X00121G011746-A101746-A131746-A71746-C91747-CP3IS215UCVEM06AE5CS-R1KJ1746-IB161746-N141746-OB16E1746-P3UDK5128NW1336-SN-SP16ASCPSD-250-04-17IC698CMX016IC698PSA350A16B-3200-0260MP3101PI3381ATV312HU22N41FK6081-6AF71-1ZZ9-ZS47VAP025V18345-10105210016ES7331-7KF02-0AB03HAC023195-001/02LS803DML:420MMID:20908923SSN-BG89ASSN-BG89D3HAC033203-0013HAC033234-0013HAC14550-46ES74143XM050AB0MDX61B0075-5A3-4-00JEPMC-AN210MP3101PI3381ENRZ-DU101746-IB161746-NI81761-L10BWA919C7010061CFS300R12KE3AGDR-71CLT9213A1794-L3386142BFHA-40C-100-E250HA-655(675)-4-2001C31194G011C31197G01RMIO-01LQ104V1DG51PS-M06D12S5-NJ1L(S)1756-ENBT1756-L611756-PA72HFD3070MR-H500ACN1C31194G011C31197G01SGMG-30A2ABSGMG-44A2ABSGMG-75A2ABAINT-14CFS450R12KE3/AGDR-71CA860-2005-T301MP3101PI33816ES7972-0AA02-0XA06GK1100-2AB006GK1102-6AA001756-CNB1756-ENBT1756-L611756-PA72SST-PB3-CLX-RLLFBM204M3707CP303250CL223E31756-OB32/A460K78.00DI801DO801MP3101PI3381NC80CPC25022A-A4P5N1041756-AP751770-XYC51402645-200IC698CHS017IC698CRE0301771SC-OMI16IC693MDL231IC693MDL330A06B-6102-H222#H520PCI-2727A140CPU67160TSXMRPC007
