KREIS ZUR STEUERUNG VON PNEUMATISCHEN AUTOMATIKSYSTEMEN

摘要

A sequencing logic circuit comprises a blocking means for preventing phase jumps caused by the untimely presence of a release signal. An inhibitor device is placed on one of the channels feeding a storage relay, placed upstream of said release signal, in such a manner as to prevent the transmission thereto of a pressure for placing it in logic state "1." This inhibitor device is actuated by the release signal and does not permit any communication between the latter and the channel controlled.
