CONTROL

Series 130 electronic control device for

proportional valves

PWM control device, with current control system for directly operated

proportional valves

Series 130 electronic control device allows to pilot any proportional valve with a maximun

current of 1 A.

It turns a standard inlet signal (0-10V or 4-20 mA) into a PWM signal to obtain at the

solenoid outlet a current which is proportional to the inlet signal.

A control system of the provided current

allows to compensate variations due to

heating of the solenoid or to the variation

of the supply voltage.It is possible to adjust

the maximum current and the minimum

current provided to the solenoid. The outlet

signal can have a ramp progress that is

adjustable between 0 and 5 s. The device

has a firmware dedicated to the proportional

valve to pilot in order to guarantee the best

performance.

Closed loop current

can be provided = 1A)
