4-20mA

4-20 mA is a robust, reliable communication protocol that has been used widely in industrial settings for many years. Analog Devices’ 4-20 mA portfolio for industrial systems offers a high level of accuracy, integration, and flexibility, with guaranteed specifications and a long life cycle not found in alternative products. Our many field proven reference designs, example circuit diagrams, and application notes ease the designers’ task of implementing customizable, 4-20 mA communications systems, while the reliability, robustness, and considerable control functionality of our drivers, DACs, ADCs, and loop interfaces address a host of system challenges. Analog Devices leads the way in industrial communications with our ever-broadening 4-20 mA product line.

ADI integrated solutions combine both the D/A converter and driver in one chip to provide the required output directly from the digital domain. Analog Devices’ portfolio of leading industrial D/A converters and drivers provides a range of programmable output ranges from standard 4 mA to 20 mA for current loop communication to ±10 V for actuator control. ADI industrial converters offer considerable control functionality and advanced on-chip diagnostics to maximize system uptime, as well as eliminate the need for costly calibration routines needed by some traditional discrete architectures. HART technology offers a complementary mode of communication to 4 mA to 20 mA that provides additional information in the form of remote diagnostics and system troubleshooting where it can be used to enhance the safety integrity level rating of a system. ADI offers a family of HART modems and 4 mA to 20 mA converters that can be used together to realize a robust, accurate, and HART Foundation registered solution. Our solutions address requirements for both loop and non-loop powered transmitters, and isolated and non-isolated analog I/O cards.
