Abstract

In this paper, a new integration of linear mapping capability with 4-20mA current loop receiver. This module allow user to change instrument variable instantly. Configurations are easy to set by using console command through serial communication port. Break in current loop or faulty current transmitter are easily detect through indicator. The implementation of the module and the test results are discussed.

본 연구에서는 4-20mA 수신기를 가진 선형매핑용량의 새로운 집적방법에 대한 것이다. 본 연구에서 제안한 모듈은 즉각적으로 기구변환을 사용자들이 편리하게 할 수 있도록 하였다. 구성은 직렬통신포트에 콘솔명령을 사용하여 쉽게 배치하였다. 전류루프나 디폴트전류송신기에서의 중단되는 현상을 표시에 의하여 쉽게 발견되도록 하였다. 이러한 모듈의 적용과 실험에 대하여 상세히 연구하였다.
