Products Intro: HART 475 Coommunicator Hand Held Communicator is a hand held interface based on HART protocol, which could perform configuration, management, maintenance and adjustment to all HARTcompatible instruments. Hand Held Communicator can be easily connected into 4~20mA loop, to achieve the configuration of instrument parameters (upper limit and lower limit etc.), the reading of instrument variables, as well as the diagnosis and maintenance of the instrument. This Communicator could support not only the HART main device (HART multiplexer etc.), but also the peer-to-peer and multidrop HART communication modes. Technical Specifications 1.
