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

The card moves the proportional valve via preset value input. Eight demand value input can be activated in binary mode, so it is possible to control speed, directional and ramp values without any analog card into the PLC.

The card use the RS232C interface, and is settable via notebook, using the kit (EWMPC).
