Model AP4003-0001 is the new version of the previous AP4003-xxxx series. Wide-ranging technology from the Ultra Slimpak II series has been utilized in this new version. This single model contains all of the input capability of previous dash numbers without the need for custom ranging from the factory. The resistance range is still 100 to 100k ohms. The default range is 0 to 100% but any portion of the span from 10% to 100% can be selected by pushbutton ranging. Four output ranges (0-5VDC, 0-10VDC, 0-20mA and 4-20mA) are available. A 15VDC output can also be used, but at a reduced drive level of 3mA. The default output is 4-20mA.

The AP4003-0001 is useful for converting potentiometer settings to voltage or current. It can be used anywhere a potentiometer or slidewire is used to determine position, displacement or rotation. The constant-voltage excitation allows use with potentiometers/slidewires with total resistances from 100 ohms to 100k ohms without affecting accuracy.
