ABSTRACT:
A programmable relay control device is provided for determining the level of at least two outputs as a function of signals present at the inputs and timing signals from a clock, comprising down-counting decades and programming and reprogramming means. This device comprises reprogrammable remanent memories and logic networks whose configuration is controlled by the outputs of said remanent memories. These logic networks comprise routing grids in which one output at most corresponds to every input, these grids receiving different input signals and intermediate variable signals and delivering parameter signals and different output signals, and a combination grid in which every output may correspond to a logic combination of the inputs, receiving said parameter signals for delivering said intermediate variable signals.
