捷晟达JSD 隔离模块接线问题[0]

Posted on 2023年11月14日 by

采集系统常需要隔离模块用于屏蔽干扰和信号转换。尤其对于输出为电压的传感器,有多个采集系统同时进行采集时需要避免电路的干扰,一般采用光电隔离模块实现。对于传感器输出为电流信号的情况下,而采集系统为电压时,需要信号转换模块。以下以捷晟达(官网地址)隔离模块为例,简单介绍接线问题。

  • JSD TA-1002-215 (0-10V转0-10V)

datasheet,一进两出模拟隔离器

  • JSD TA-1001-D15(4-20mA转0-10V)

datasheet,一进一出模拟隔离器

接线示意图如下:无源隔离器,此时两线制压力传感器需要供电的接法

  • JSD TA-1022-D15(4-20mA转0-10V)

datasheet,一进两出

接线示意图,有源隔离器,此时两线制压力传感器需要供电的接法

补充说明:JSD 隔离变送器 目录
