An external power supply is required for each output. The following supply voltage values
apply for PROFIBUS PA and the pulse/frequency/switch output:
Order code for "Output"
Minimum terminal

Option A
1) 2)
: 4-20 mA HART For 4 mA: ≥ DC 18 V
For 20 mA: ≥ DC 14 V DC 35 V
Option B

For 4 mA: ≥ DC 18 V
For 20 mA: ≥ DC 14 V DC 35 V
Option C
1) 2)
: 4-20 mA HART, 4-20 mA For 4 mA: ≥ DC 18 V
For 20 mA: ≥ DC 14 V DC 30 V
Option G
3)
: PROFIBUS PA, pulse/frequency/switch output 9 V DC 32 V
1) External supply voltage of the power supply unit with load.
2) For device versions with SD03 local display: The terminal voltage must be increased by DC 2 V if backlighting is
used.
3) For device version with SD03 local display: The terminal voltage must be increased by DC 0.5 V if backlighting is
used.
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 (→  26)
