Operating voltage
For proper operation, the
MD 10.010
requires depending of its version:
Material No. 527320:
85 … 250 VAC
Material No. 528240:
18 … 30 VDC
Only operate the measured value display within the defined op-
erating voltage range and type.
Undervoltage may result in malfunction; overvoltage can lead to
irreversible damage.
Supply voltage for sensor
The measurement display provides a voltage source for the operation of
a sensor (or even several sensors).
The supplied nominal voltage is 24 VDC, its tolerance is type depending:
Material No. 527320:
±15 %
Material No. 528240
2
: ±20 %
The maximum load current is limited to 160 mA.
Analog input
The jumper in the housing cover selects the signal characteristic (modus)
of the analog input of the display (current or voltage).
If the bridge is placed on the left contact pin pair (
Voltage
) a voltage signal
is expected. If the plug connects the right pair of pins (
Current
), a current
signal must be active.

The supply voltage of the display is connected through, with a series resistance of 25
.
