HART Communication Protocol

The HART (Highway Addressable Remote Transducer) protocol is a widely accepted standard for digitally enhanced communication with instrumentation within the process industries.

HART Communication Protocol
  • Overview
  • Documentation
  • Resources


  • The HART Protocol is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring systems
  • We offer a variety of analog I/O modules with HART connectivity
  • Additional products are available from our Encompass™ Partners

Additional Information
