7.1.5 Requirements for the supply unit
Supply voltage
Transmitter
An external power supply is required for each output.
The following supply voltage values apply for the outputs available:
Supply voltage for a compact version without a local display
1)
Order code for "Output" Minimum
terminal voltage
2)
Maximum
terminal voltage
Option A: 4-20 mA HART ≥ DC 12 V DC 35 V
Option B: 4-20 mA HART, pulse/
frequency/switch output
≥ DC 12 V DC 35 V
Option C: 4-20 mA HART + 4-20 mA
analog
≥ DC 12 V DC 30 V
Option D: 4-20 mA HART, pulse/
frequency/switch output, 4-20 mA current
input
3)
≥ DC 12 V DC 35 V
1) In event of external supply voltage of the power supply unit with load
2) The minimum terminal voltage increases if local operation is used: see the following table
3) Voltage drop 2.2 to 3 V for 3.59 to 22 mA
