4-Channels HART Analog Output Module
Product model:UW7521

UW7521 4-Channels HART analog output module integrates 4 isolated analog output module to verify, lock, protect and export the analog output data. According to the configuration requirement, the data output can be maintained or output specified value in abnormal condition; It supports HART Equipment Communication and instrument equipment management (AMS); Communication of HART equipment does not affect the real-time data acquisition and procession.  Hardware configuration software with the instrument equipment system manage, is convenient for users to remote view, edit, configure field devices record all the related operations, and improve maintenance efficiency with integrated digital signal between the each Heart field devices and conventional digital signal in the same platform.

    • High-reliability Sub-modules, to-channel isolation, channel-to-channel inter-isolation, to-channel power supply, to-channel Removal/Insertion Under Power, meeting requirements of high reliability & security fields like nuclear power and emergency shutdown;

   Automatic module recognition ,support analog 4-20mA output and online quick release through software configuration;

    •    Automatic ambience-temperature compensation and zero & gain correction; No further calibration or maintenance necessity;

    •   Abnormal condition configuration, can select either output-holding or output user-set value when abnormal conditions happen;

    •   HART facilities directly via UWnTeK control engineering application software platform to achieve the remote control management functions;

    • Less ripples, less temperature shift, more efficient, more reliable, better voltage isolation withstand. Protection functions include soft-start, input short-circuit protection, output power limitation, channel power-supply current limitation, etc.

    • Equipped with industrial wiring terminal sets, cancelled accessories such as system rack, bottom support, terminal blocks and wiring cables for easier maintenance

    • Internal optional input voting algorithm, input self-diagnosis and error report mechanism; Non-Redundant  configurations  scheme.
