HART modem

HART® technology is an accompaniment to many of Analog Devices’ tailored industrial 4 mA to 20 mA converters. 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.
