Valve Driver Efficiently and Economically Manages Proportional Valves
The D1 allows a 12 or 24 VDC power supply, to accommodate most applications. Its valve deadband, dither amplitude and maximum current are all adjustable. For applications using programmable logic controllers (PLCs) or computers, the D1 easily interfaces with the valve, eliminating the need to write valve management routines that consume valuable processing cycles needed for other machine functions.
Its digital closed loop current control implemented by software efficiently compensates for different types of perturbations such as change in the input voltage and change in the coil resistance due to temperature. Other features of the D1 Driver include short circuit protection, highly efficient design (no heat sink is required) and LED indicators for power and status/fault activity. With a temperature range of -40 to 65°C. (-40 to 150°F), the versatile D1 is designed for use in a variety of environments.
The unit’s enclosed format is ideal for panel mount systems or applications where the electronics will be exposed to end-users. The D1 comes with a DIN clip for rail mounting, or the clip can be removed for flat surface mounting either from within the enclosure or from the bottom.
