ABSTRACT:
Electrical sequence control system. There is described an electrical sequence control system which is controlled according to a predetermined program by means of a switching circuit wherein the outputs of the binary counter are connected with n bits to the data inputs of the decoder and the address inputs of a multiplexer, the output of the latter being applied to one input of an AND-gate and the second input of said AND-gate being connected to a rectangular wave generator. The output of the AND-gate is connected to the input of the binary counter and the connection of the output of the multiplexer with the input of the binary counter acts as a return when one of the input signals at the multiplexer corresponds with the address input.
