FIELD DEVICE WITH AN INPUT UNIT

摘要

The invention relates to a field device with an input unit (1) comprising a first number of switch elements (S1 to S4; S1 to S8) in order to generate first input signals (E11 to E14) and a second number of magnetically actuatable sensor elements (H1 to H5) assigned to the switch elements (S1 to S4) ) in order to generate second input signals (E21 to E24) which are OR-linked to the first input signals (E11 to E14). Each switch element (S1 to S4) is assigned to at least two sensor elements (H1 to H5) which are arranged and connected such that the respective second input signal (E21 to E24) is output only when at least two specified sensor elements (H1 to H5) assigned to a switch element (S1) are actuated.
