7.1.6 Requirements for the supply unit
Supply voltage
Transmitter
An external power supply is required for each output.
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 ≥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
Option G: PROFIBUS PA, pulse/frequency/
switch output
≥DC 9 V DC 32 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
Increase in minimum terminal voltage
Local operation
Increase in minimum
terminal voltage
Order code for "Display; Operation", option C:
Local operation SD02
+ DC 1 V
Order code for "Display; Operation", option E:
Local operation SD03 with lighting
(backlighting not used)
+ DC 1 V
Order code for "Display; Operation", option E:
Local operation SD03 with lighting
(backlighting used)
+ DC 3 V
Load
Load for current output:
0 to 500 Ω, depending on the external supply voltage of the
power supply unit
Calculation of the maximum load
Depending on the supply voltage of the power supply unit (U
S
), the maximum load (R
B
)
including line resistance must be observed to ensure adequate terminal voltage at the
device. In doing so, observe the minimum terminal voltage (→  30)
