Abstract (en)
[origin: EP1808837A2] The apparatus has signal lines (7, 8) that provide a life-zero signal current (Is) representing a measuring signal with defined minimal and maximal values of 4 milliampere (mA) and 20 mA in a measuring mode. An operating condition is fed with high power requirements in a supply mode. The signal lines provide a supply current with a value above a maximal value of the life-zero signal current such as above 21 mA. A control signal activates the supply mode. The control signal is provided by a pushbutton (16).
