The Duplomatic EWM-S-B* cards are designed for an easy stroke control of hydraulic actuators connected to a simple PLC with only I/O functions. The target position can be selected by a binary input up to 8 different position.
Typical applications are positioning drives, handling axis and fast transportable drives (adaptation of non-linear valve characteristics).The card controls a directional proportional valve with integrated electronics. As option, an integrated power amplifier is available.
This card allows an optimal use of overlapped and zero overlapped proportional valves.
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).
