Abstract

The invention is a field device with an input unit comprising a first number of switch elements in order to generate first input signals and a second number of magnetically actuatable sensor elements assigned to the switch elements in order to generate second input signals which are OR-linked to the first input signals. Each switch element is assigned to at least two sensor elements, which are arranged and connected such that the respective second input signal is output only when at least two specified sensor elements assigned to a switch element are activated.
