A safety related analog input module based on diagnosis and redundancy

Abstract

This paper introduces a safety-related analog input module to achieve data acquisition of 4-20mA current signals. It is an integral part of the safety-instrumented systems (SIS) which is used to provide critical control and safety applications for automation users. In order to ensure the performance of analog input circuit in good condition, a combination… (More)
