Adjustable characteristic function

A modulating positioning signal DC 0..35 V from a controller drives the actuator. The
angular rotation is proportional to the positioning signal. Using potentiometer "Uo", you
can set the offset for DC 0...5 V, and with potentiometer "
DC 2...30 V.

The adjustable span
Define the adjustable span
signal of Y = DC 2...10 V. The offset Uo thus amounts to 2 V. The angle of rotation is
90°.
