KL3021X1-BA1 Emerson AI 4-20mA HART CHARM

Description

The KL3021X1-BA1 Emerson AI 4-20mA HART CHARM is an analog input module designed for industrial automation systems, with key technical specifications derived from comparable Emerson CHARM products. It operates on DC 12-24V power, with a maximum ripple of 200mV and operating current less than 50mA. For communication, it supports HART protocol alongside Modbus RTU via RS485, with selectable baud rates including 1200, 2400, 4800, 9600, and 19200 bps. The module features 4 independent 4-20mA HART current input loops, each compatible with loop loads ranging from 230 to 1100 ohms. It is built to perform reliably in harsh industrial environments, with an operating temperature range of -20 degrees Celsius to 80 degrees Celsius and relative humidity tolerance of 10% to 80%. Physical specifications include dimensions of 135x72x42mm and a weight of 141g. Additional potential features include passive 4-20mA HART output capabilities, compliance with global safety certifications such as ATEX, IECEx, and CE, and adherence to functional safety standards like IEC 61508 for use in safety-rated applications.
