6FX1120-7BB01模块6FX1120-7BB01模块机械安全是一项复杂的系统工程，需要考虑的因素很多，比如机械设备特点、工艺操作特点、安全设计理念等等。一般来说，安全控制系统应该包括安全输入设备（如急停按钮、安全门限位开关或联锁开关、安全光栅或光幕、双手控制按钮），安全控制电气元件（如安全继电器、安全PLC和安全总线）和安全输出控制（如主回路中的接触器、继电器或阀等）。其中，安全PLC是在应用中值得***关注的产品。所谓安全PLC，就是专门为条件苛刻的任务或安全相关的应用而设计的PLC，在其失效时不会对人员安全或过程安全带来***。在一台安全PLC根据要求达到了特定的可靠性/故障概率等级时，就意味着它具有广泛的自诊断能力，可以监测各个方面的硬件状态、程序执行状态和操作系统状态。此外，安全PLC还必须能够执行标准机构（例如TUV、FM等）认证的必须的故障安全动作，而这些故障安全动作都是根据特定的原则设计，并满足安全标准（如IEC61508和EN954-1等）中定义的要求。另外，安全PLC还可能包括警卫保护预警和权限管理的内容，用来保护安全PLC不受来自外界的干扰。从范围看，实践证明已经采用安全PLC的行业包括汽车、机床、机械、船舶等行业，以及过程工业中的石化、炼油、电厂、锅炉控制和燃烧控制、高压应用等。此外，它还可以在一些远程遥控、无人值守以及维护费用十分昂贵的应用场合（例如大型储罐区）一显身手。TEXASINSTRUMENTSPLC500-5114AUSPP5005114A500-2109TexasInstrumentsTIDistributedBaseController5002109N742TexasInstruments565-2120TEXASINSTRUMENTSPLC305-CPUUSPP305CPUASEABROWNBOVERI3HAC-17484-2/0​0NSPP3HAC17484200TexasInstrumentsModel:PM550-210PowerSupplySIEMENSA1-106-101-509USPPA1106101509PanasonicACServoDriverMSD083A1XXVALLENBRADLEY6185-CAAAAAZUSPP6185CAAAAAZASEABROWNBOVERI5730030-DRUSPP5730030DRTEXASINSTRUMENTSPLC2490685USPP2490685HITACHIGPCL01HUSPPGPCL01HQTY1PanasonicACServoDriverMSDA015A1AFreeShipPerceptronDSPFrameGrabber495-019196K495-0192500-0192*new/unused*PanasonicACServoDriveDV451S075#37772ASEABROWNBOVERIYPQ-110AUSPPYPQ110AASEABROWNBOVERI3BHT300025R1NSPP3BHT300025R1PILZ301060NSFP301060ASEABROWNBOVERIACS601-0011-4-​000B1500801USPPACS60100114000​B2ASEABROWNBOVERIACH501-015-2-0​0P2USPPACH501015200P2TEXASINSTRUMENTSPLC5TI-3100USPP5TI3100TEXASINSTRUMENTS5TI-1034-1,5TISequencerRepairedATLASCOPCO038240-00500USPP03824000500TEXASINSTRUMENTS30505BPROGRAMMABLECONTROLLERASSEMBLYPanasonicACServoDriveMSD021P1EA03workingASEABROWNBOVERI1923RA00140000​0STDUSPP1923RA00140000​0STEXASINSTRUMENTSPLC505-4016AUSPP5054016ATexasInstruments305-PROGPanasonicMFA010LA2NSACServoMotor100WTEXASINSTRUMENTSPLCT***90/101MAUSPPT***90101MATexasInstruments5TI-2001TEXASINSTRUMENTSPLC315-DDNSPP315DDTexasInstrumentsMod550LoopAccessModulePM550-400SYMAX8881-MD2USPP8881MD2MOTOROLA01-W3875B-04EUSPP01W3875B04EPERCEPTRON912-0008USPP9120008ASEABROWNBOVERISI4662708TUSPPSI4662708TPanasonicACServoDriverMSD043A1XXFBAUMANN54R-25000NSFP54R25000ExpeditedshippingailableASEABROWNBOVERI57120001-P/5USPP57120001P5TexasInstrumentsTI140Controller140-1111MITSUBISHIMR-J2S-500BUSPPMRJ2S500BASEABROWNBOVERI29118337BUSPP29118337BRELIANCEELECTRIC0-51831-5NSFP0518315TEXASINSTRUMENTSPLC500-5012NSPP5005012OnePanasonicMSDA043D1AACServoDriverFreeShipTEXASINSTRUMENTSPLCPM550-116USPPPM550116ASEABROWNBOVERIACS601-0009-5-​000B1200000USPPACS60100095000​B2AYDINCONTROLS460-5045-501USPP4605045501NEWSIEMENSTEXASINSTRUMENTSTIINPUTMODULE500-5008LENZE9953212FNFP9953212PanasonicServoDriveMSD203A1VV200-230V2KWFreeShipASEABROWNBOVERI57360001-A/6USPP57360001A6PanasonicServoMotorM***011P1ANewTEXASINSTRUMENTSPLC08-35546-000USPP0835546000ASEABROWNBOVERIACS6010095000B​1200000USPPACS6010095000B​12ASEABROWNBOVERI3HAB6182-1USPP3HAB61821(AG01)PANASONICM***041A1AACSERVOMOTORWORKINGASEABROWNBOVERIEH550C-Q1NSPPEH550CQ1PANASONICMSDA023A1ASERVODRIVEAC200-230VAC505-4932ATexasInstrumentsSiemensTI505-4932AN6ASEABROWNBOVERI3HAA2121-3NSPP3HAA21213ASEABROWNBOVERIYT204001-FCUSPPYT204001FCALLENBRADLEY1336F-BRF100-A​N-ENUSPP1336FBRF100ANE​NASEABROWNBOVERIACS601-0016-5-​00B1200000USPPACS6010016500B​12TEXASINSTRUMENTSPLC505-6308NSPP5056308CORCOM160ADT6SUSPP160ADT6STexasInstrumentsPM550-410TexasInstrumentsRTU-T059-TTERMINATIONPANELASEABROWNBOVERIYB560103-AMUSPPYB560103AMASEABROWNBOVERI3BSE004939R1NSPP3BSE004939R1)
