IC646MPM101***IC646MPM101***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。TEXASINSTRUMENTSPLC500-5023NSFP5005023STIMS4344BUSPPMS4344BTEXASINSTRUMENTSPLC990-307USPP990307(AB01)DRIVER-ACSERVOPANASONICMATSUSHITAMSDA041A1A100V400W,400ASEABROWNBOVERILC820TL-R0639USPPLC820TLR0639TEXASINSTRUMENTSPLC100-3101USPP1003101TEXASINSTRUMENTSPLC565-2820USPP5652820ASEABROWNBOVERIYB560103-BD/1USPPYB560103BD1PanasonicACServoMotorMHMD082P1C750WFreeShipTEXASINSTRUMENTS500-5037-A*USED*MOOREPRODUCTS16201-1-7NSPP1620117ASEABROWNBOVERI57310001-CX/2USPP57310001CX2PanasonicACServoMotorMHMA102P1G1kWTEXASINSTRUMENTSPLC505-3516NSPP5053516SAJF//PANASONICADKF5085AAACSERVODRIVERUNITUSED7MT-1504TexasInstrumentsTIThermocouple7MT1504G309ASEABROWNBOVERIDSTC-456NSFPDST56TEXASINSTRUMENTSPLC2238675-0002USPP22386750002TEXASINSTRUMENTS500-5037-AANALOGINPUTMODULENEW5005037APanasonic750WServoDriverMCDDT3520L01(freeshipping)PANASONICACSERVOMOTORMQMA011A2BHEWLETTPACKARDTEST&MEASURE1645AUSPP1645AOneM***A5AZA1APanasonicACServoMotorFreeShipTEXASINSTRUMENTSPLC500-7103USPP5007103TexasInstruments7203interfaceASEABROWNBOVERI48931006-KSUSPP48931006KSKEYENCECORPLC-2100USPPLC2100(AG01)PANASONICM***A041A1EACSERVOMOTORWORKINGFOXBORO280H-SBBA-TSA-​GUSPP280HSBBATSAG505-7202TexasInstruments/Si​emens5057202R-33ASEABROWNBOVERI3ADT306200R1NSPP3ADT306200R1ASEABROWNBOVERIL***63600USPPL***63600TEXASINSTRUMENTSPLC500-2161NSFP5002161HONEYWELLTC-O061USPPTCO061TEXASINSTRUMENTSPLC55PL8312000328USPP55PL8312000328ASEABROWNBOVERIDSDX-110NSPPDSDX110Siemens/TI575-2103CPUModuleVMEPLCTexasInstruments5752103PanasonicACServoMotorMHMD042G1UNIBFreeShipASEABROWNBOVERI086370-001NSFP086370001FOXBORO138SP-4-EUSPP138SP4ETexasInstrumentsProgramableControlerPLCM#305-02BTISiemensCTi500-50355005035ProgrammableBasic0006PLCASEABROWNBOVERIEH300C-1LUSPPEH300C1LPanasonicACServoDriverMSD2A121EFreeShipTEXASINSTRUMENTSPLC510-2101USPP5102101ASEABROWNBOVERI3HAB2209-1USPP3HAB22091TEXASINSTRUMENTS500-2151POWERSUPPLY5002151ASEABROWNBOVERIQFVF502USPPQFVF502KTRON9191-700810USPP9191700810PanasonicACServoMotorM***042A5FFreeShipPanasonicM***D082PJAACServoMotorPanasonicACServoMotorM***3AZA2AXFreeShipGENERALELECTRICCK08CE311JNSFPCK08CE311JASEABROWNBOVERID***B-138USPPD***B138USEDPerceptron96KDSPFrameGrabber495-0191RevNASEABROWNBOVERIDSQC-236BUSPPDSQC236BTEXASINSTRUMENTSPLC510USPP510ASEABROWNBOVERIDSPC157USPPDSPC157PanasonicMSD203A1VACServoDriverASEABROWNBOVERIEH550G-PRL11NSFPEH550GPRL11PanasonicACSERVOMOTORAMKA100B10KA0AMKA100B10KAOFreeShipASEABROWNBOVERIHIEE320604R1NSFPHIEE320604R1TEXASINSTRUMENTS505-7354USPP5057354SAFTRONICSGP10E1ST32030B​1USPPGP10E1ST32030B​1OnePanasonicACServoMotor***202A1GFreeShipAPWMCLEAN28-0226-003USPP280226003TEXASINSTRUMENTSPLC560-2120WNSFP5602120WDANFOSSVLT5022P-T5-C2​0-SB-R3-D0-F00​-A00-C0NSPPVLT5022PT5C20S​BRPanasonicServoMotorM***011P1BFreeShipASEABROWNBOVERI086369-001USPP086369001TexasInstrumentsSequencerType#571SEQUENCER!ALLENBRADLEY825-PUSPP825P)
