Abstract
A radio unit for a plant of process automation technology. The radio unit has a power circuit, which serves to derive first and second supply voltages from a voltage source, wherein the power circuit has a first output, via which the first supply voltage is tappable to serve for driving an operating electronics of the radio unit, wherein the power circuit has at least a second output, via which the at least a second supply voltage is tappable to serve for driving at least one field device connectable to the second output.

A radio unit for a plant of process automation technology, comprising:
- a voltage source;
- operating electronics;
- a power circuit, which serves to derive first and second supply voltages from said voltage source, wherein:
- said power circuit has a first output, via which said first supply voltage is tappable to serve for driving said operating electronics of the radio unit;
- said power circuit has at least a second output, via which the at least a second supply voltage is tappable to serve for driving at least one field device connectable to the second output.
A method for operating a radio unit for a plant of process automation, wherein the radio unit has a power circuit, by which an operating electronics of the radio unit is supplied with a first supply voltage and a field device connected to the radio unit is supplied with a second supply voltage, the method comprising the steps of:
- deriving the first and second supply voltages from a voltage source;
- and
- the first supply voltage is tapped via a first connection of the power circuit and the second supply voltage via a second connection of the power circuit.
