EDM-M* - Digital amplifier

The series 30 EDM-M* card is a digital amplifier for open-loop proportional valves' control. It is designed for rail mounting type: DIN EN 50022.
The card supplies the current to the solenoid, according to the reference signal, and independently of temperature variations or load.

The card is available in three versions: for the control of a single solenoid valve (M1), a double solenoid valve (M2), and two single solenoid valves (M3) by two independent channels.

EWM-A-SV - Analog amplifier

EWM-A-SV - designed for dynamic control of servo valves with the current output controlled in a closed-loop.

This card is an analog amplifier that receives an analog input +/- 10V to move the servo valves via different values of current adjustable by DIL switches on-board with steps of 10mA.

This card has an embedded auxiliary positive and negative supply to power an external potentiometer.

EWM-A-PV - Universal amplifier

EWM-A-PV - designed for the control of proportional, directional pressure or throttle valves. The current output is controlled in a closed-loop. The card is set up only via software through an on-board USB-B port.

Function control mode can be configured: for dual solenoids proportional valves, with an analog command signal of ±10V or 4÷20 mA.

Also, for one or two single solenoids' proportional (throttle, pressure, directional) valves, with an analog input signal of 0 ÷10V or 4 ÷20 mA, and single or dual solenoids' proportional valves, with either, pre-programmed values or selectable by 3 digital inputs.
