Computer controlled signal transformer for potentiometric input signals to be converted to standardized voltage or current signals. The signal conditioner supplies the potentiometric sensors with a highly stable constant voltage. The wiper signal is sampled without load via a high-resistance input stage and transformed into a proportional standardized output signal. The adjustment of the desired output signal (current or voltage, switchable) is done easily by a teach-in procedure using only 2 buttons on the front panel of the device. The input span can be limited down to 80 % of the total input range. This permits standardized output signals to be adjusted if the maximum travel or angle of the sensor is not completelyutilized.

The electronic circuitry is accommodated in a plastic housing designed for mounting to a standard DIN EN 50022 mounting rail. The wide operating voltage range allows use of unstabilized direct voltage sources. High-grade DC/DC transformers are used in the models with electrically isolated supply voltage and signal conditioning.

The excellent linearity and temperature drift characteristics of the MUP400 ensure optimum electrical implementation of potentiometers. By locating the MUP400 physically close to the potentiometer, reliable and interference free transmission of the position signal is guaranteed, even over long transmission distances.

• High precision signal conditioner Interfaces with potentiometric position sensors
• Auto-calibration: one button press to set zero and another for span
• User selectable output of either 0 to 10 V or 4 to 20 mA
