Circuit for detecting the positions of contactors in a turbine engine

摘要

A circuit for detecting individual positions of a plurality of electrical contactors, including a plurality of modules each including a contactor having k separate contact positions each connected in series to a resistor associated with an integer status value between 1 and k and separate from other status values of a same module, each module being associated with a weighting coefficient and the weighting coefficients following a geometric progression of no less than k+1, the electrical conductance value of each resistor being equal to the status value thereof multiplied by the weighting coefficient of the module thereof.

1. A circuit for detecting individual positions of a plurality of electrical contactors, comprising:
a plurality of modules connected in parallel or in series and each comprising a contactor with k distinct contact positions each connected in series to a resistor associated with a whole state value of between 1 and k, in which the state values in a same module are in distinct pairs; each module is associated with a weighting coefficient and these weighting coefficients follow a geometric progression of reason greater than or equal to k+1; and wherein the electrical conductance or ohmic resistance value of each respective resistor is equal to its state value multiplied by the weighting coefficient of its module.
