Analogue command value conditioning<br />
< Analogue command value card for controlling valves with integral electronics<br />
< Suitable for generating, linking and normalizing command value signals<br />
< Configuration and parameterization of the command value card using potentiometers<br />
< Inversion of the internal command value signal via 24V input or by means of jumpers<br />
< Selection of ramp time through quadrant recognition<br />
(24V input) or ramp time call-ups (24V inputs)<br />
< Change-over of the ramp time range using jumpers<br />
< Characteristic curve correction through separately adjustable step-change heights and<br />
maximum values<br />
< Enable input<br />
