Functional Description
The control electronics is intended for the open-loop control of proportional valves with one solenoid. Its great advantage is its miniature design
in form of a socket for a standardized DIN connector base.
The unit supplies a variable current proportional to the reference signal, independently of temperature or load impedance variations.
To optimizie valve control and minimize valve hysterezis the unit contains a PWM stage to supply the solenoid.
The card's top surface contains two revolving selectors, a terminal block to connect supply and control wires, and a three-digit LED display.
The selector marked as "SELECT" is used to select the parameter to be adjusted. The second selector, marked as "ADJUST", is used to set the desired
value. In basic operational mode, the display shows an input/output parameter value; in adjustment mode, the selected parameter abbreviation
and the value being set up are indicated. The correct input signal type must be selected before operation.

Attention: A cable with a circular cross-section and outside diameter of 4 to 6 mm should be used for the electronics supply,
only this way the declared degree of IP protection can be secured.
