Overview

Description

The 4mA to 20mA current loop is the dominant standard for sensor systems in many industries, primarily because it is the simplest option to configure and connect. It also uses less wiring and connections than other signals, therefore reducing overall system cost. In addition, in large locations, it is better for traveling long distances, since current doesn't degrade like voltage does.

This winning combination shows a possible receiver solution with Renesas’ precision digital power monitor (DPM), stable power source, and low power processing capabilities of the Arm® Cortex®-based RA2A1 MCU.

System Benefits:

  • Low power and signal processing features of Renesas’ RA2A1 Arm Cortex-M23 microcontroller
  • Precision digital power monitoring with the ISL28022 and low current consumption
  • Stable voltage from Renesas’ ISL9001A for low-noise and high-PSRR applications
