IC800BIDK020输入模块IC800BIDK020输入模块维控plc在恒压供暖系统的应用一、简介供暖系统主要用于北方冬季暖气系统供暖，控制两电机对供暖系统水压控制在恒定范围内，用plc控制减小了工作人员工作量，无需值班人员看守。二、特点1、使用维控的PLC，PLC型号为20MT。2、PLC程序内置算法，通过modbus通讯读取水压值以及变频器当前频率值，当水压不够使plc控制变频器让补水泵开始工作，一定时间内，启动1#补水泵变频启动，变频一定时间即变频达到50hz，水压仍然达不到值，1#补水泵切换到工频，2#变频启动，直到水压保持在设定值内，当水压恒定在设定值内，即1#工频2#变频运行，此时如果变频器频率低于设定的频率运行超过设定时间，将自动切换到1#变频启动状态。2#电机停止运行。3、系统中还包含无水信号、变频器故障报警信号。水箱中无水信号、变频器故障报警信号送达plc，系统停止工作。三、组成部分1、PLC负责动作的直接控制和外界反馈的信息的采集，实现供水系统的自动运作和故障检测。MITSUBISHIMTA-100USPPMTA100NewinBox505-7028TexasInstruments/Si​emens5057028N741PanasonicACSERVOMOTORMUMS022A1E0S200WFreeShipASEABROWNBOVERI48990001-FKUSPP48990001FKTEXASINSTRUMENTSPLC555-1101NSPP5551101ASEABROWNBOVERINBRA-658CUSPPNBRA658CALLENBRADLEY1336-GM2FNFP1336GM2PanasonicACServoMotor***152A1C1.5kWwithPlugsPanasonicMQMZ012A2UACSERVOMOTORNEWDEZURIKP2000USPPP2000ASEABROWNBOVERIQHMM101USPPQHMM101TEXASINSTRUMENTSPLC505-7012ANSPP5057012ATexasInstrumentVPU200-3102ASEABROWNBOVERIDSQC-314AUSPPDSQC314AKOLLMORGENINDBDS4A-203J-000​1-104A21PUSPPBDS4A203J00011​01ASEABROWNBOVERID***B-144USPPD***B144GENERALELECTRICCR209U000AEAUSPPCR209U000AEAASEABROWNBOVERI3BSE013228R1USPP3BSE013228R1ASEABROWNBOVERI57411546USPP57411546COMPUMOTORPK-130USPPPK130OnePanasonicMSDA043D1AACServoDriverFreeShipPanasonicACServoDriverMCDDT3520003FreeshipPanasonicACServoMotorM***D022P1UNEWASEABROWNBOVERIYT204001-DTUSPPYT204001DTPanasonicACServoMotorM***082A4BFreeShipTEXASINSTRUMENTSPLC7MT-600NSFP7MT600ASEABROWNBOVERIYB560103-CCUSPPYB560103CCExpeditedshippingailablePanasonicACServoMotorMHMA102P1G1kWTEXASINSTRUMENTSPLC7MT-700USPP7MT700TISIEMENSTEXASINSTRUMENTSDUALCOMMPORT500-5029ASEABROWNBOVERI1953RAA0110009​0STDUSPP1953RAA0110009​0SOMRONCV500-MC221USPPCV500MC221ASEABROWNBOVERI3HAB6182-1USPP3HAB61821TEXASINSTRUMENTSPLC305-LICUSPP305LICASEABROWNBOVERIDSPC-171USPPDSPC171ASEABROWNBOVERI086369-001USPP086369001BALDOR35***98R334G1NSFP35***98R334G1ASEABROWNBOVERIPM665NSFPPM665PanasonicACServoMotorM***042A1GFreeShipSIEMENS6ES5-943-7UA11USPP6ES59437UA11ASEABROWNBOVERIYT212001-USPPYT212001NEWSIEMENSTEXASINSTRUMENTSTIINPUTMODULE500-5008TEXASINSTRUMENTS500-50235005023SAJF//PANASONICMFDDTA390L01ACSERVOUSEDTexasInstrumentsPM550-210Perceptron912-0008TricamSurfaceSensorUSMOTORS65-16347-670-F​077766USPP6516347670F077​76TEXASINSTRUMENTS5TII/0EXPANDER5TI-5500TEXASINSTRUMENTSPLC2490005-0001USPP24900050001PanasonicACServoDriveMQDB011AAD03new0190-19214ASEABROWNBOVERI58096067USPP58096067LAMBDALM-EE014USPPLMEE014OMRONF3S-A321-DUSPPF3SA321DPanasonicM***022J1SXACServoMotorwith60daywarrantyGEFANUCIC600LX648USPPIC600LX648GOULDSHAWMUTA055C1D0R0-300​ENSFPA055C1D0R0300EMOOREPRODUCTS16201-1-7NSPP1620117PACIFICSCIENTIFICR43HEAA-R2-NS-​VS-02NSPPR43HEAAR2NSVS0​2TEXASINSTRUMENTSPLC500-5013NSFP5005013PanasonicMADDT1207003ACServo200-240VACPERCEPTRON916-4079DIGITALCONTOURLASERSENSORREVCC0400-X0000-Y0​126-Z0287ALLENBRADLEY1336-151140NSPP1336151140ASEABROWNBOVERIFILM-VARCAPACITOR1N03300A08FTEXASINSTRUMENTSPLCPWB2490891-000​1AUSPPPWB24908910001​AOMRONF3SN-A0207P14USPPF3SNA0207P14GENERALELECTRICDS3800DOAAUSPPDS3800DOAATEXASINSTRUMENTSPLC7MT-210NSPP7MT210PanasonicACServoMotorM***A021A1FFreeShipASEABROWNBOVERIIOP-05USPPIOP05ASEABROWNBOVERIDSQC-325USPPDSQC325ASEABROWNBOVERI05MS00USPP05MS00)
