The Task
Transmission and conversion of bipolar standard 0 ... ±20 mA and 0 ... ±10 V signals frequently used in industry, e.g., for speed monitoring with tachogenerators.

The Problems
Measuring errors occur due to potential differences when bipolar measuring signals are transmitted. In addition, the signal matching previously required calibration of the isolators.

The Solution
Knick provides a tailor-made solution. Thanks to the calibrated selection of the input and output parameters using DIP switches, VariTrans A 26000 universal signal conditioners can be used without complicated readjustment. The broad-range power supply for all common supply voltages from 20 to 253 V AC/DC offers maximum flexibility.
