Abstract (en)
[origin: WO2010043468A1] The invention relates to a field device (10) of process automation technology, having an interface (11) for the output of a current signal, a specifying unit (12) which specifies a value upon which a current signal to be output via the interface (11) is dependent. The invention comprises a first actuatable current sink (1) and a second actuatable current sink (2), the first actuatable current sink (1) and the second actuatable current sink (2) each adjustable to a predetermined rated current, and the first actuatable current sink (1) and the second actuatable current sink (2) being connected to the interface (11) such that the current signal applied to the interface is substantially dependent upon the lowest rated current of the predetermined rated currents at which the first actuatable current sink (1) and the second actuatable current sink (2) are set.
