| Abstract: | The paper,based on the analog signal transmission link of the research,developed the 0.1% precision analog signal distribution module. This article introduces the application background of the module, focuses on the hardware design. This module collects standard industrial analog signal into the output of the three channel standard current signal which are isolated between each other. In actual applications, the module has a lot of advantages such as the high measurement accuracy , high anti-interference a-... |
