1.4. Block diagram
Parker electronic modules PWDXXA-40X for rail
mounting are compact, easy to install and provide
time-saving wiring by disconnectable terminals.
The digital design of the circuit results in good
accuracy and optimal adaption for proportional
directional control valves with position sensor by
a comfortable interface program.
1.5. Characteristics
The described electronic unit combines all neces-
sary functions for the optimal operation of pro-
portional directional control valves with position
sensor. The most important features are:
• digital circuit design
• parametrizable control as position control for
valve spool or external closed loop control
• constant current control
• differential input stage with different signal options
• monitor output for spool stroke/feedback, status
output
• four quadrant ramp function
• enable input for solenoid driver
• status indicator
• parametering by serial interface RS-232C
• connection by disconnectable terminals
• compatible to the relevant European EMC-
standards
• Comfortable PC user software, free of charge:
