PROPORTIONAL VALVES — ELECTRONIC DRIVERS FOR OPEN LOOP CONTROL

    HD-US-DAS2 SERIES

    HUADE LOGO

    The HD-US-DAS2 is Huade's electronic driver series for controlling proportional valves with one or two solenoids. Powered at 8–32 VDC, it manages two independent output channels with adjustable current up to 3 A each, separately configurable rise and fall ramps, and adjustable dither frequency. Compatibility with both voltage and current analogue signals —makes it integrable into any industrial control architecture.

    Benefits

    • Independent bidirectional control of both solenoids in a single driver, with no need for two separate amplifiers
    • Rise and fall ramps configurable separately for each channel, to adapt the dynamic response of the valve to the requirements of each phase of the cycle
    • Wide supply range (8–32 VDC) and compatibility with all standard analogue signal formats, simplifying integration into existing systems
    • Integrated diagnostics with error codes displayed on screen, reducing fault identification and resolution time
