简介

4-20mA 电流环是工业领域传感器系统的主要标准是 因为它具有极为简单的配置和连接方式。另外,它也比其他传输信号使用更少的布线及接线,因此降低了系统总体成本。在大空间的应用场景中,它更适合远距离传输,因为电流不像电压那样容易衰减。

这一成功的组合展示了一种可行的发射器解决方案,包含我们的精密数字电源监视器(DPM)、稳定的电源﹑带有低功耗和模拟功能的16位RL78/I1D MCU

系统优势:

  • RL78/I1D 是一个具有超低功耗和丰富模拟功能的 MCU,适用于检测器和传感器应用
  • ISL80410 是高输入电压,可调输出电压低静态电流线性稳压器,是“始终在线”应用的理想选择
  • 基于瑞萨电子的 ISL21080 纳安功耗(典型电流 310nA)电压基准源的精密电压
