Application description

Connection of 2-wire-measurement transmitter, e.g. for elimination of ground loops. 

The isolation amplifier ExTVA-500-UC supplies the sensor with auxiliary energy and transmits the 4...20mA measurement signal to the output. A bidirectional HART communication with SMART-transmitters is possible. The optional intrinsically safe input circuit fulfills die ignition protection class intriniscally safe (i)
