Proportional amplifier type EV

Proportional amplifiers actuate proportional solenoid valves by converting an input signal into a corresponding control current.

The proportional amplifier type EV is available as a module for top-hat rail mounting or, alternatively, as a card for a card holder. Highly precise functions are possible thanks to the feedback measurement at the valve outputs.

Thanks to the excellent control accuracy and highly precise feedback measurement, even challenging hydraulic applications can easily be realised.

A multi-turn potentiometer is used to configure the valve parameters such as the base and maximum current, dither and ramps.

The control parameters (Imin, Imax, dither, ramp times) are configured using either pushbuttons or a potentiometer.
