The control electronics is intended for controlling of
proportional valves with one control solenoid. Its great
advantage is a miniature design in form of a socket for a
standardized DIN connector base. On the electronic
card’s top surface, two revolving selectors, a terminal
block for connecting of supply and control wires, and
three-position LED display are attached. The selector
marked as “SELECT” serves for selecting of parameters
for setting up. The second selector, marked as
“ADJUST”, serves for setting up of a desired value. In a
basic mode, the display shows an input/output
parameter value; conversely, in a setting mode, a
selected parameter abbreviation and the value being set
up are indicated. Setting up of an input control signal
selected type .

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