PWD00A-400-19 PCD00A-400-22/18-30VDC PCD00A-400-15 E-Module for Proportional Directional Control Valves PWD00A PWDXXA PCD00A

Electronic modules PWDXXA-400 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 adaptation for proportional directional control valves with a position sensor through a comfortable interface program.

Features
The described electronic unit combines all necessary functions for the optimal operation of proportional directional control valves with a position transducer or valves in a closed loop
systems. 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 USB interface • 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 • Technology function
“linearization” • The PC software can be downloaded free of charge
