The DM3801 valve driver provides a bipolar current drive to a current controlled valve.

The unit uses a pulse-width modulated square wave output that switches at a high frequency. The duty cycle of the output wave changes to create an average DC current through the valve magnet winding.

The DM3801 valve driver is housed in an aluminum DIN rail mountable case with a stainless steel mounting plate and plastic front panel.

Connections are made via two 4-pin plug-in terminal blocks. These terminal blocks allow the product to be removed without disconnecting the wires.
