The EWM-A-PV card is a universal power amplifier, for proportional valves, with output current regulated in closed loop, for DIN EN 50022 rail mounting.
The power amplifier generates a PWM signal up to 2.6 A. Depending on how it is configured, the card allows the control of one proportional directional valve (2 solenoids) or the control with analog signal of one or two single solenoid proportional valves (flow rate, pressure, directional ..) or the control via three digital input signals of a single or double solenoid proportional valve; ramps and max eight values per command must be pre-configured via software. There are functions for curve linearization and failures monitoring.
To configure it you need the EWMPC/20 software, which can be downloaded from this page. Connection by USB port on the front panel.
