KFD2-CR4-1.2O Transformer Isolated Amplifier.The device supplies 2-wire and 3-wire transmitters, and can also be used with 2-wire current sources.

It transfers the analog input signal as two isolated current values.

Both outputs provide a 0/4-20mA current corresponding to the input signal. The minimum available field voltage is 16V at 20mA.
