7.1.4 Requirements for the supply unit
Supply voltage
An external power supply is required for each output. The following supply voltage values
apply for the 4-20 mA and 4-20 mA HART current output:

1) External supply voltage of the power supply unit with load (→  21)
2) For device versions with local display SD03: The terminal voltage must be increased by DC 2 V if backlighting is
used.
Load
Load for current output: 0 to 500 Ω, depending on the external supply voltage of the power
