Parker electronic modules PWDXXA-40µ 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.
Features
The described electronic unit combines all necessary functions for the optimal operation of proportional directional control valves with position transducer or valves in closed loop systems (series D1FC, Dµ1FS). The most important features are:
Digital circuit design
Parameterizable position control of valve spool
Constant current control
Differential input stage with different signal options
Monitor output for spool stroke
Four-quadrant ramp function
Enable input for solenoid driver
Status indicator
Parametering by serial interface RS-232C
Connection by disconnectable terminals
In combination with valves without spool feedback
Pressure control with proportional pressure valve and pressure sensor
Position control with proportional DC valve and actuator position transducer
Optional technology function "linearization"
