The 4-20mA 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.
Renesas' Lab on the Cloud is an online environment where Renesas solutions, including popular evaluation boards, winning combinations and software, are hosted in a remote lab that customers access and test online.
This board uses the standard 4-20mA loop to transmit data over large distances in industrial environments. It is resistant to surrounding noise and, unlike voltage based interfaces, the current in the loop will remain constant.
Renesas' complementary product portfolios of Analog + Power + Embedded Processing + Connectivity work together to deliver comprehensive solutions. Our product experts have developed "Winning Combinations," compelling product combinations that help our customers accelerate their designs and get to market faster.
