The EDM-M* card is a digital amplifier for open loop proportional valves control by a PWM stage.
The card supplies the current to the solenoid according to the reference signal and independently of temperature variations or load impedance.
The card is available in 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.
Each version is available with different maximum current settings and switching frequencies (PWM), optimized according to the relevant valve.
Card setup via software only, through on-board micro USB port or by IO-Link.
— The EDM-J* card is a digital amplifier intended for closed loop control of single solenoid or double solenoids proportional and servo-proportional valves.
— The card controls the position of the spool of the valve according to the reference signal, ensuring linear regulation with minimum hysteresis.
— The card is available in different versions according to the valve type and reference signal types.
— The front panel houses the leds for diagnostic and card operation, and a micro-USB port intended for card setup.
This card is designed for a dynamic control of servovalves with the current output controlled in closed loop.
This card is an analog amplifier that receive an analog input +/- 10V to move the servovalves via different values of current adjustable by DIL switches on board with steps of 10mA.
This card has embedded an auxiliary supply positive and negative to power an external potentiometer.
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.
