    Extremely low failure rate  (MTBF of 280 years) due to reduced self-heating
  • High accuracy and temperature stability
    Gain error 0.2 % and temperature coefficient 0.01 %/K
  • Calibrated range selection
    without complicated readjustments
  • Easy configuration
    DIP switch accessible from outside

The VariTrans A 21000 isolates, transmits and converts 0 to 20/4 to 20 mA and 0 to 10 V with a high level of accuracy. In spite of its modular housing being only 6 mm wide, the new VariTrans isolation amplifier provides maximum protection of personnel and equipment through protective separation up to a working voltage of 300 V conforming to EN 61140. The test voltage is 2.5 kV AC. It can be supplied with either 24 V DC or 230 V AC.
