The Duplomatic EWM-S-AA card is designed for an easy stroke positioning control of hydraulic actuators in closed loop systems. Target positions are defined by the external command input, and an accuracy of approx. 0,01% of the sensor stroke can be achieved.
Typical applications are positioning drives.
The card controls a directional proportional valve with integrated electronics and allows an optimal use of overlapped and zero-overlapped proportional valves.
Velocities can be defined also by an external speed command. Versions with output value in voltage, in current. or with an integrated power amplifier are available.
Internal function and failure are monitored with two digital output easy to read.
The card use the RS232C interface, and is settable via notebook, using the kit (EWMPC).
