EDM-M*

The EDM-M* card is a digital amplifier for open loop proportional valves control. It is designed for rail mounting type: DIN EN 50022. The unit supplies a variable current in proportion to the reference signal and independently of temperature variations or load impedance.




.

EWM-S-B*

The EWM-S-B* cards are designed for an easy stroke controlhydraulic actuators connected to a simple PLC with only I/O functions.



.

EWM-S-AA

The EWM-S-AA card is designed for an easy strokecontrol of hydraulic actuators in closed loop systems.



.

EWM-S-AD

This card has been developed for closed loop positioninghydraulics actuators where an high accuracy is, using a digital sensor with SSI interface to measure the position.


.

EWM-S-DAD

Card for positioning and velocity stroke control with Profibus communication interface

EWM-SP-DAD

Card for axis control (stroke and pressure) with Profibus communication interface

EWM-MS-AA

This card has been developed for an easy synchronization of two actuators with an overriding synchronization controller.

EWM-SS-DAD

Card for axis syncronization control for systems from 2 to 24 axis.

EWM-P-AA

The EWM-P-AA has been developed for pressure closed loopof pressure reducing and pressure relief valves, with an embedded power amplifier for proportional valves.

EWM-PQ-AA

The EWM-PQ-AA has been developed as a classic p/Qbut it work well also with high response valves via an analogue command input for pressure and flow.

EWM-DP

This card has been developed for the displacement,and max power / torque limitation control for servo pumps.

EWM-PID-AA

This card has been developed for universal closed loop control.

EWM-RL

This card is designed to control proportional valvesone or two solenoids, with the current output controlled in open loop.
