DC 24 V
The display is only ever operated in a 4 ... 20 mA current loop. A direct
connection to a voltage supply (e.g. DC 24 V) will lead to the display
being damaged and will invalidate the warranty.
For a functional check, the display must be powered from a mA source
(e.g. mA transmitter or calibrator).
In normal operation, the display is connected in series with a 4 ... 20 mA
transmitter or connected to the 4 ... 20 mA analogue output of an
instrument.
