Isolated Standard Signal Conditioner

VariTrans A 21000

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.
