Protocol converters DA1500 series data adapter is suitable Scene 1, the control system is facing the kind of complex software protocol access; 2, system engineering, instrument mix of old and new, mixed protocol software; 3, Zhu inadequate control unit interfaces; an overview ??? DA1500 series data adapter focused on instrumentation software protocol standardization; it can be standardized to a different protocol simple common protocol --MODBUS (RTU), to achieve a unified data access, especially for resources like serial PLC, industrial touch screen like the very limited control equipment; in actual engineering project, the peripheral instruments are often subject to change by the master device port resources and software protocols, very difficult to implement; If you replace the master device, often because the price is too high budget and risk and lose transform value; DA1500 series can play in this type of problem in a very good adaptation action to solve the problem for device interconnection; ??? in system integration, various communication protocols are numerous, but the main device serial scarce resources the problem is particularly prominent; under limited hardware resources, use DA1500 series can easily solve their problem of interconnection; Features 1, wide voltage power supply: 9-28VDC, and provides overvoltage protection and reverse polarity protection; 2, the socket mode easy installation, maintenance; 3, the software fault codes, LED intelligent fault indication, convenient on-site problem diagnosis; 4, the machine address and communication parameters can be software modifications; 5, support for field communication parameters reset, do not worry about forgetting address; 6, the user According to need, set your own communication interface isolation mode; 7, rail mounting, easy loading and unloading modules, increase or decrease; 8, special software protocol provides custom development; technical parameters 1, power supply voltage: 9-28V wide voltage power supply under (normal circumstances provide DC12V or DC24V power); 2, the communication module physical interface: RS485 (connection using the socket mode); 3, IP rating: IP30 or more; 4, temperature, humidity: 5-60 degrees, 75%; 5, housing Size: DIN35mm rail fixed installation; 6 overall size: 100 × 40 × 50mm; 7, output voltage: DC12V voltage; how to purchase adapted equipment selection table Model Remarks DA1500 HACH LDO AQII probe DA1501 NPW150 DA1502 COD203???? ?
