Abstract
A field device of process automation technology having an interface for output of an electrical current signal and a specifying unit, which provides a value, on which depends an electrical current signal to be output via the interface. A first controllable electrical current sink and a second controllable electrical current sink are provided. The first controllable electrical current sink and the second controllable electrical current sink are settable to predeterminable electrical current levels, and that the first controllable electrical current sink and the second controllable electrical current sink are connected with the interface in such a manner that the electrical current signal which at the interface essentially depends on the lower of the predeterminable electrical current levels, to which the first controllable electrical current sink and the second controllable electrical current sink are set.
