   Sunyuan Technology is a high-tech enterprise in Shenzhen in 2007 and a national high-tech enterprise in 2011-2018. The company takes "customer's success, our value" as the business philosophy, accordance to the requirements of ISO2012 quality technology management system, insists on improving, promote and innovating, continuously improving product quality, reducing production cost, expanding product application range, and innovating research and development. Products to adapt to the current evolving development of electronic information technology and meet the needs of user product innovation and upgrading.

   Sunyuan Technology has 17 years of experience in design, production and application of DC-DC Converter, data acquisition, isolation amplifier and display control instrument. The whole series has more than 50 national patents and software copyrights. The company's professional team of engineers provides solutions for industrial field intelligent control and instrumentation and sensor signal interference suppression, analog signal isolation and amplification conversion, load matching, ground-line isolation, power isolation conversion, data acquisition, AD/DA conversion, etc. A lot of solutions.

   The patented "Low cost intelligent 2 channels data acquisition control system terminal" is mainly used for the ISO 4021 series of analog data acquisition of the company. This product can realize signal acquisition between the sensor and the host to detect analog signals or Control remote devices. Through software configuration, it can be used in a variety of sensor types, including: analog signal input, analog signal output, and digital signal input / output (I / O), ISO 4021 series products can be applied to RS232 or RS485 bus industrial automation control system, 4-20mA / 0-5V signal measurement, monitoring and control, small signal measurement and industrial field signal isolation and long-line transmission etc.

   ISO 4021 series products are designed and manufactured according to industry standards. The signal is isolated between the input and output, it can withstand 3000VDC isolation voltage, strong anti-interference ability and high reliability. Operating temperature range - 25 ° C ~ +70 ° C.Products include power isolation, signal isolation, linearization, AD conversion and RS485 serial communication. Each serial port can connect up to 256 ISO 4021 series modules. The communication mode adopts ASCII code communication protocol or Modbus RTU communication protocol. The instruction set is compatible with ADAM module. The baud rate can be set by code and can be linked with other manufacturers' control modules. On the same RS-485 bus, it is convenient for computer programming. 

   In the industrial intelligent system, the analog current or voltage signal output by the PLC, PCC AO module or SCADA or DCS system usually directly controls the remote execution device, which often causes signal attenuation and distortion due to long-distance transmission. It will also cause signal error due to other external signal interference, affecting the normal operation of the whole system. This patented product can convert 4-20mA analog quantity into RS485/232 digital quantity (AD conversion) and then communicate with MODBUS RTU bus system. Then, you can also pair another ISO DA module of our company to restore RS232/485 to analog (DA conversion), which can effectively improve the system's anti-interference ability, and communicate the baud rate and address through RS485 bus. Settings, in some cases can also reduce wiring, reduce equipment control costs and improve the reliability of industrial control systems.
