1757-DNBUPG65输出模块;1757-DNBUPG65输出模块;1757-DNBUPG65输出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。YASKAWAELECTRIC***C-2000-2USPP***C20002WESTINGHOUSE7381A93G05USPP7381A93G05ASEABROWNBOVERIYT212003-UBUSPPYT212003UBTEXASINSTRUMENTSPLC7MT-1300NSFP7MT1300TexasInstruments500-5037BAILEYCONTROLSNP***02USPPNP***02TEXASINSTRUMENTSPLC500-2114USPP5002114TEXASINSTRUMENTSPLC505-3508NSFP5053508TexasInstruments5TI-2459514TexasInstruments7MT400SIEMENS6ES5-946-3UA21USPP6ES59463UA21ASEABROWNBOVERI3ADT306200R1NSPP3ADT306200R1TEXASINSTRUMENTSPLC305-25NNSFP30525NORIENTALMOTORBLD180A-MKUSPPBLD180AMKTEXASINSTRUMENTSPLC505-4932USPP5054932TEXASINSTRUMENTSPLC505-CP1434TFNSPP505CP1434TFPanasonicMinasACServoDriverMSD43A1XXMSD023A1XXMSD013A1XX400W60dayswarTEXASINSTRUMENTSPLC530-1102USPP5301102TEXASINSTRUMENTSPLCVPU-200USPPVPU200TexasInstruments5TI-1032-2(AG01)PANASONICM***011A1EECP-16A-11-J213​A-SPM***011AT7SERVOMOTORWORKINGASEABROWNBOVERIINNPM-22NSFPINNPM22TEXASINSTRUMENTSPLC7MT-100AUSPP7MT100AITESIEMENSCED63B015LNSFPCED63B015LELECTROCRAFT9101-1133USPP91011133TEXASINSTRUMENTSPLC505-2557NSFP5052557ASEABROWNBOVERIDSQC-313USPPDSQC313PanasonicMSD153A1VACServoDriverALLENBRADLEY1784-KTK1NSPP1784KTK1ALLENBRADLEY1775-AD1USPP1775AD1ASEABROWNBOVERIYT204001-FSI1USPPYT204001FSI1TexasInstruments500-2151-APowerSupply500-2151(TESTED)PanasonicACServoDriverMSDA083A1AFreeShipASEABROWNBOVERI(ABB)DSDP140BTexasInstrumentTMS9901NLIntegratedCircuit*NEW*PanasonicACServoMotorM***022ASBFreeShipPanasonicM***102H1CACSERVOMOTORALLENBRADLEY1336-C010-EADUSPP1336C010EADASEABROWNBOVERIGJV3-0743-11-R​0001USPPGJV3074311R000​1TEXASINSTRUMENTSPLC500-5056USPP5005056Expeditedshippingailable(AG01)PANASONICM***021ABFACSERVOMOTORWORKINGTEXASINSTRUMENTSPLC505-5151USPP5055151TEXASINSTRUMENTSPLC505-4332NSFP5054332TEXASINSTRUMENTSPLC510-2102USPP5102102#TEXASINSTRUMENTS505SIEMENSTEXASINSTRUMENTS500-5031OUTPUTMODULEASEABROWNBOVERIHIEE300025R2NSFPHIEE300025R2ALLENBRADLEY849-ZOA32NSFP849ZOA32PanasonicServoDriveADKA400BPFADIworking(AB02)DV8C150SDDBPANASONICSERVODRIVERUSEDWORKINGASEABROWNBOVERIQDBB-153MUSPPQDBB153MALLENBRADLEY825-PUSPP825PASEABROWNBOVERI57088630USPP57088630(AS01)MFA250LB2NLPANASONICACSERVOMOTORUSEDWORKINGTEXASINSTRUMENTSPLC5TI-1021-1USPP5TI10211PERCEPTRONTRICAMCONTOURSENSOR9110007ASEABROWNBOVERIS6N600BW-4USPPS6N600BW4TEXASINSTRUMENTSPLC505-4232AUSPP5054232ABRISTOLBABCOCKRTU-3305USPPRTU3305PanasonicM***022J1SXACServoMotorwith60daywarrantyFLUIDCOMPONENTSLT81A-A1D00000​1DA001446BB075​3C2A201A1A1B1A​10002B1AUSPPLT81AA1TEXASINSTRUMENTSPLC505-4616NSFP5054616TEXASINSTRUMENTS500-5056**(AJ01)MSDA083A1AM***A082S1FPANASONICSERVOMOTORUSEDWORKINGASEABROWNBOVERIQMVU501USPPQMVU501ASEABROWNBOVERIFILM-VARCAPACITOR1N03300A08FPACIFICSCIENTIFICR46GENA-TS-LS-​NV-02USPPR46GENATSLSNV0​2PanasonicMFA020LE2NSCACServoMotorwith60daywarrantyASEABROWNBOVERIYPQ108AUSPPYPQ108AASEABROWNBOVERI5716075KUSPP5716075KALLENBRADLEY1785-CHBMNSPP1785CHBMTEXASINSTRUMENTSPLC7MT-400NSPP7MT400TEXASINSTRUMENTSPLC3RW2-E045NSFP3RW2E045BARBERCOLMANA-11844-1USPPA118441TIGEAR35S15RNSPP35S15RPanasonicMinasACServoDriverMSD43A1XXMSD023A1XXMSD013A1XX400W60dayswarTexasInstrumentsPM550-102)
