E-Module for Proportional Valves

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””
