output
VEGABAR 87 • 4 ... 20 mA/HART
Fig. 15: Connection compartment - double chamber housing
1 Voltage supply, signal output
2 For display and adjustment module or interface adapter
3 For external display and adjustment unit
4 Ground terminal for connection of the cable screening
To make a second measured value available for use, you can use the
supplementary electronics " Additional current output".
Both current outputs are passive and need a power supply.
