7.4.5 Output signals

Galvanic isolation
All circuits for inputs, outputs and power supply are galvanically isolated from each other.
Active current One or two current outputs are available depending on MS code position 13.
output lout
Depending on the measured value, the active current output delivers 4 – 20 mA.
It may be used for output of the following measured values:
▪ Flow rate (mass, volume, net partial component flow of a mixture)
▪ Density
▪ Temperature
▪ Pressure
▪ Concentration
For HART communication devices, it is supplied on the current output lout1. The current
output may be operated in compliance with the NAMUR NE43 standard.
