HART Modem Communications

A range of devices which conform to the HART (Highway Addressable Remote Transducer) industrial communications protocol. HART communications frequently utilize 4-20mA networks and are widely used in Automation and Control applications. The HART standard provides for both point-to-point (analogue or digital) and multi-drop (digital only) modes of operation, the latter using a fixed loop current of 4mA.
