Network Controls - HART with DTM

BRAND: Limitorque

HART® (Highway Addressable Remote Transducer) is a digital communication protocol that is based upon the Bell 202 telephone communication standard. By using FSK (frequency shift keying) to superimpose low level digital signals on top of an analog 4-20 mA signal, two simultaneous communications channels exist. The 4-20 mA signal communicates the primary measured value, and the digital signal communicates additional device information to the plant control system.

Configurations

Network Protocol
HART (Highway Addressable Remote Transducer) was developed by Emerson for the purpose of communicating a digital signal over analog (4-20 mA) input. It is perhaps the most widely used type of digital protocol.
