1771-ACN15***;1771-ACN15***;1771-ACN15***为适应工业环境使用，与一般控制装置相比较，PLC机有以下特点：1.可靠性高，抗干扰能力强工业生产对控制设备的可靠性要求：①平均故障间隔时间长②故障修复时间（平均修复时间）短任何电子设备产生的故障，通常为两种：①偶发性故障。由于外界恶劣环境如电磁干扰、超高温、超低温、过电压、欠电压、振动等引起的故障。这类故障，只要不引起系统部件的损坏，一旦环境条件***正常，系统也随之***正常。但对PLC而言，受外界影响后，内部存储的信息可能被***。②***性故障。由于元器件不可***的***而引起的故障。如果能限制偶发性故障的发生条件，如果能使PLC在恶劣环境中不受影响或能把影响的后果限制在范围，使PLC在恶劣条件消失后自动***正常，这样就能提高平均故障间隔时间；如果能在PLC上增加一些诊断措施和适当的保护手段，在***性故障出现时，能很快查出故障发生点，并将故障限制在局部，就能降低PLC的平均修复时间。为此，各PLC的生产厂商在硬件和软件方面采取了多种措施，使PLC除了本身具有较强的自诊断能力，能及时给出出错信息，停止运行等待修复外，还使PLC具有了很强的抗干扰能力。PanasonicMCDDT3520053ACServoDriverFreeShipSIEB&MEYER26.39.67USPP263967505-6850ATexasInstrumentsSiemensSimaticTI505-6850-AR100GEFANUC44A297062-G01USPP44A297062G01ASEABROWNBOVERIACS800-U1-0006​-5-L502-L503-N​660USPPACS800U100065L​52FOXBOROD3005PK-BBNSPPD3005PKBBASEABROWNBOVERI58096067USPP58096067TEXASINSTRUMENTSPLC164-2111NSFP1642111ASEABROWNBOVERIE-32235USPPE32235ALLENBRADLEY1326AB-B410G-2​1-K4USPP1326ABB410G21K​4ASEABROWNBOVERI3BSE004940R1NSFP3BSE004940R1ASEABROWNBOVERIPSTB57060070USPPPSTB57060070GENERALELECTRICDS3800HXPA1D1DUSPPDS3800HXPA1D1DRELIANCEELECTRIC413338-1YAUSPP4133381YATEXASINSTRUMENTSPLC505-4308NSPP5054308505-6840TexasInstruments/Si​emensTI5056840R31ASEABROWNBOVERI3HAB2242-1USPP3HAB22421ASEABROWNBOVERIP-HC-BRC-30000​000NSFPPHCBRC30000000NEWPANASONICServoMotorM***A041A1ACNC/ROUTERTEXASINSTRUMENTSPLC500-5029USPP5005029ASEABROWNBOVERI6232BP10810USPP6232BP10810ASEABROWNBOVERIYB560103-CHUSPPYB560103CHTEXASINSTRUMENTSPLC500-5884USPP5005884TEXASINSTRUMENTSPLC505-3508NSFP5053508(AG01)PANASONICM***A042A1BACSERVOMOTORWORKINGPerceptron912-0008TricamSurfaceSensorPanasonicServoMotorM***D012P1UM***DO12P1UNIBFreShipBALDORDBSC1105-BAAUSPPDBSC1105BAAGENERALELECTRICDS3800DOAAUSPPDS3800DOAASIEMENSTEXASINSTRUMENTSMONITORCVU100OMRONNT631C-ST141B-​***USPPNT631CST141BEV​2FINCOR5002695USPP5002695TEXASINSTRUMENTSPLC0983801-0003USPP09838010003PanasonicACServoMotorM***082D1ATEXASINSTRUMENTSPLC505-4432USPP5054432NewandOriginalPanasonicACServoDriverMSDA043A1AWITH60DAYSWARRANTYPanasonicACServoMotorMHMD082P1SASEABROWNBOVERI57510001-AAUSPP57510001AAKISTLERMORSESONO2BAABAGYYUSPPSONO2BAABAGYYTEXASINSTRUMENTSPLCVPU-200-3102USPPVPU2003102PanasonicServoDriverMCDHT3520ENewinBoxFreeShipALLENBRADLEY1785-LT2NSFP1785LT2FANUCA06B-6077-H111USPPA06B6077H111ExpeditedshippingailableTEXASINSTRUMENTSPLC425DC-CPUUSPP425D***UALLENBRADLEY1336-C007-EADUSPP1336C007EADTEXASINSTRUMENTSPLC505-2557USPP5052557PERCEPTRONUS400D45VNICETEXASINSTRUMENTSSERIES500CONTROLLER520C-1102PanasonicACServoMDDDT55401.5KWDriverASEABROWNBOVERI5730030-DNUSPP5730030DNPanasonicACServoDriverMSD011A0XXALLENBRADLEY813S-VOHUSPP813SVOHTexasInstruments500-5001TexasInstrumentsPM550-212ASEABROWNBOVERI750191000BNSFP750191000BTEXASINSTRUMENTS5TI-1034-2USEDSEQUENCERMODULE5TI10342TEXASINSTRUMENTSPLC500-7203USPP5007203SYMAX8881-MD2USPP8881MD2505-4832TexasInstruments/Si​emensTI5054832R25TEXASINSTRUMENTSPLC305-14ABM-TMUSPP30514ABMTMALLENBRADLEY150-A35NB-NANSFP150A35NBNAASEABROWNBOVERI57360001-EB/1USPP57360001EB1MODICONPLS-4USPPPLS4RELIANCEELECTRIC45C-381NSFP45C381PanasonicACServoMotorM***042N2NFreeShipASEABROWNBOVERI57088613USPP57088613TEXASINSTRUMENTSPLC500-6224USPP5006224ASEABROWNBOVERI3HAC-17484-2/0​0NSPP3HAC17484200TexasInstruments7MT900SANYODENKIP80B22350HBV27USPPP80B22350HBV27TexasInstrumentPM550-200PanasonicACServoDriverMBDDT2210003NewinboxFreeShipASEABROWNBOVERI57288531NSPP57288531TEXASINSTRUMENTSPLC505-4916AUSPP5054916ANIKKIDENSONPSA-TMTA-752USPPNPSATMTA752ASEABROWNBOVERI57510001-AUSPP57510001AASEABROWNBOVERIS6H600BWUSPPS6H600BW)
