The Task
Industrial applications require the transmission and conversion of various standard signals (0 ... 20 mA, 4 ... 20 mA and 0 ... 10 V) with maximum precision.

The Problems
Long transmission paths can cause potential differences that lead to errors in the measuring result. Different products were also required for different signals and supply voltages.

The Solution
The VariTrans P 15000 signal conditioners feature excellent transmission quality combined with calibrated standard signal switching using DIP switches and a broad-range power supply.

The Housing
At a width of just 12.5 mm, the modular housing with pluggable screw terminals allows for simple and fast assembly and pre-wiring of enclosures. Housings with fixed screw terminals are also available for extremely high mechanical loads.

The easy-to-open housing allows for simple configuration of the input and output ranges and provides good protection against contact and unintentional adjustment.

The Advantages
The analog transmission of the measurement signal with transformer isolation and the new digitally controlled range selection guarantee almost perfect signal transmission:

  • Gain error only 0.08 %
  • Excellent pulse formation
  • Extremely low residual ripple
  • Maximum long-term stability and reliability

The Technology
A microcontroller monitors the control element settings and controls the calibrated range selection. Interference with the signal transmission – due to contact resistance in the range switch, for example – is ruled out in this manner.

Thanks to the VariPower power supply for all common supply voltages from 20 to 253 V AC/DC, the devices can be used internationally with virtually all supply voltages. The extremely low power consumption and the related minimal self-heating significantly increase reliability. The result: a 5-year warranty.
