PROPORTIONAL VALVES — ELECTRONIC DRIVERS FOR OPEN LOOP CONTROL

HD-US-DAS2 SERIES

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
