DESCRIPTION
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 a 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.
TYPICAL APPLICATIONS
Hydraulic proportional valve driver
MOUNTING
The module mounts on a standard H-35 DIN rail. A spring latch holds it in place.
The module is demounted by using a screwdriver to release the latch. The latch
release is accessible at the bottom of the module.
