HART Solutions from ABB



The HART protocol is the preferred way to convey digital signals from traditional field instrumentation while preserving the 4-20 mA signal. By overlaying a small digital signal over the 4-20 A current, it gives access to instrument status and allows for parameterization and set up of device characteristics.

The HART communication solution is backward compatible with the installed base of instrumentation in use today in securing investments in cabling and control strategies.

ABB is equipped to answer all your needs for a comprehensive HART solution. With a worldwide installed base of about one million HART compatible instruments, ABB is one of the leading suppliers of automation solutions for this technology. This includes systems, stand alone tools, interface products and field instrumentation.


Our experience and technology will enable you to seamlessly integrate the best products from different suppliers, for true interoperability.
