ANALOG AMPLIFIER FOR SERVOVALVE CONTROL EWM-A-SV
Descripcion
The EWM-A-SV card is an analogue amplifier for servo valves with output current regulated in closed loop, for DIN EN 50022 rail mounting.
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, up to 200 mA. The output current is controlled in closed loop, independently of the power supply and the resistance of the solenoids. This card has an embedded auxiliary supply positive and negative to power an external potentiometer.
