Abstract
The safety control device with digital input and analog output, is intended to deliver a mean output power above a specified threshold when two binary input sequences which are complementary or in phase opposition are applied to the input and an output power appreciably below the threshold in all other cases. It comprises a primary voltage source (18) supplying a cascade of several modules (16.sub.1 , . . . , 16.sub.k) each having an AC converter bridge and a rectifier, each branch of the AC converter bridge being controlled by one of the sequences.
