Signal amplifier EWM-A-PV

EWM-A-PV- Universal amplifier for proportional valves This card is designed for proportional valves control: directional, pressure or throttle valves. Current output controlled in closed loop. — Function control mode as parameter to be configured: - for dual solenoids proportional valves,with analogue command signal ±10V or 4÷20 mA. - for one or two single solenoid proportional valves (throttle, pressure, directional..), with analogue input signal 0 ÷10V or 4 ÷20 mA. - for proportional valves, single or dual solenoids either, with pre-programmed values, selectable by 3 digital inputs. — Card setup via software only, through an on-board USB-B port.
