Abstract

The circuit controls automatic pneumatic systems, comprising modules each with a bistable tipping circuit with passages connected to a pressure source, a registering input moving it into logic state 1, a cancellation input moving it into logic state 0, and a control output connected to a user unit. The registering input is supplied from the output of an AND-grid, and the cancellation one from signals derived from the control output of a subsequent tipping circuit. The AND-grid has a first input from the output of a preceding tipping circuit and a second one is fed by signals from a user unit controlled by the tipping circuit before the grid. The signals delivered to a particular module (11) are transferred via a locking passage (rp, rx, ra, rb) to a pneumatic barrier circuit (Op, Px) on one of the passages (Cp, Cx, Ca, Cb) through which the medium flows to the tipping circuit (12) of the module and which it can interrupt at this point.
