1794-IF8IH控制器1794-IF8IH控制器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。ASEABROWNBOVERI3HAA3563-AMA/0USPP3HAA3563AMA0ASEABROWNBOVERIGNT0137211P5USPPGNT0137211P5ASEABROWNBOVERIYYT-102CUSPPYYT102CTEXASINSTRUMENTS505-4832USPP5054832TEXASINSTRUMENTSPLC500-2153NSFP5002153TexasInstruments500-2109CommunicationModuleAssemblyTEXASINSTRUMENTSPLC505-7002NSPP5057002TEXASINSTRUMENTSPLC525-1104USPP5251104PanasonicACServoDriverMSDZ023A1AFreeShipTEXASINSTRUMENTSPLC949025-000USPP949025000ASEABROWNBOVERIS4H250MW-2S4WNSFPS4H250MW2S4WPanasonicMHMD02P1UACServoMotorInput30ACGEFANUC44A297062-G01USPP44A297062G01PANASONICACSERVODRIVERMDD203A1W200V50/60HZ2.0KW2500P/RHASEAseaBrownBoveriABBAxodynServoDriveD05010/R0004PanasonicACServoMotorM***011P1CNewinBoxFreeShipTexasInstruments505-4616***ARCPU-700-AUSPPCPU700ATEXASINSTRUMENTSPLC560-2122USPP5602122GEFANUCIC650AEM000USPPIC650AEM000TexasInstruments500-5052ResistanceTempDetectorTIGENERALELECTRIC193W-277ABG02USPP193W277ABG02PanasonicACServoDriverMSD103A1VVFreeShipTEXASINSTRUMENTSPLC500-5037AUSPP5005037AASEABROWNBOVERI58130435NSPP58130435ASEABROWNBOVERIYB560103-CE-26USPPYB560103CE26PanasonicACServoMotorM***A04211AFreeShipBAILEYCONTROLSIMFBS-01NSFPIMFBS01TEXASINSTRUMENTSPLCPWB2490891-0001AUSPPPWB24908910001APanasonicACServoDriverMSDA083A1AFreeShipTEXASINSTRUMENTSPLC305-01ZNSFP30501ZTEXASINSTRUMENTSPLC500-2101USPP5002101ROCHESTERINSTRUMENTSYSTEMSCL-9001USPPCL9001LIMITRONKTU-3000NSFPKTU3000PanasonicACServoDriverMADDT1207052FreeshipGEFANUCIC3600AOAL1D1USPPIC3600AOAL1D1SQUAREDMAP36500USPPMAP36500TEXASINSTRUMENTSPLC500-5006USPP5005006TEXASINSTRUMENTSPLC500-5828AUSPP5005828AASEABROWNBOVERIXI678004-ACM/9USPPXI678004AC***DATALOGICDS6300-100-010USPPDS6300100010PanasonicACServoDriverMSDA103A1AFreeShipTEXASINSTRUMENTSPLC505-7016USPP5057016ASEABROWNBOVERIACS501-025-4-00P5USPPACS501025400P5ASEABROWNBOVERI1912RA001100000STDUSPP1912RA001100000SALLENBRADLEY2711-K6C1L1USPP2711K6C1L1TexasInstruments435-CPUPANASONICMSDA023A1ASERVODRIVEAC200-230VACASEABROWNBOVERIDSCA-125AUSPPDSCA125ATEXASINSTRUMENTSPLC505-6860USPP5056860FANUCA05B-2351-02NSPPA05B235102AUTOMATEDLOGICSE6104NSFPSE6104ASEABROWNBOVERI750191000BNSFP750191000BSQUAREDMAL-36400USPPMAL36400ASEABROWNBOVERI1SDA046043R1NSFP1SDA046043R1PanasonicMFA150LB5NPJACServoMotorPanasonicACServoMotorM***012A1EEFreeShip500-2109TexasInstrumentsTIDistributedBaseController5002109N742ASEABROWNBOVERI7525A67G10NSPP7525A67G10ROBERTSHAWRMSC-GPCUSPPRMSCGPCPanasonicACSERVOMOTORAMKA100B10KA0AMKA100B10KAOFreeShipASEABROWNBOVERIQK-140-1R6500USPPQK1401R6500ASEABROWNBOVERININT-52NSFPNINT52TEXASINSTRUMENTSPLC500-2112USPP5002112ASEABROWNBOVERI57288531USPP57288531DELTATAUDATASYS3A0-602804-108NSPP3A0602804108ASEABROWNBOVERI57520001-BZUSPP57520001BZTEXASINSTRUMENTSPLC945170-0001-MUSPP9451700001MGEFANUCTGT-S000-1-1-AAUSPPTGTS00011AATEXASINSTRUMENTSPLC500-5056USPP5005056TEXASINSTRUMENTSPLCU-01ZNSFPU01ZACDCREV-804B-2448-9001USPPREV804B24489001)
