Standard 0/4...20 mA and 0...10 V signals are galvanically isolated and converted into any standard output signals. The analog measurement signal transmission with transformer potential isolation and the digitally controlled measurement range switching guarantee virtually perfect signal transmission with a gain error of just 0.08 %, while at the same time providing excellent pulse formation and extremely low residual ripple with maximum long term stability and reliability. Suitable for applications requiring a high level of isolation between the input and output: basic isolation 1000V AC/DC. Test voltage 4000 V AC.

The VariTrans A 21000 isolates, transmits and converts 0 … 20/4 … 20 mA and 0 … 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 24V DC or 230V AC.
