5.4 Supplementary electronics
To make a second measured value available for use, you can use the supplementary electron-
ics - additional current output.
Both current outputs are passive and need a power supply.

1 First current output (I) - Voltage supply and signal output (HART)
2 Second current output (II) - Voltage supply and signal output (without HART)
3 Ground terminal for connection of the cable screen
The radio module PLICSMOBILE is an external GSM/GPRS radio unit for transmission of mea-
sured values and for remote parameter adjustment.
