Abstract: The paper presents an 18-input air-operated logical "OR" module on the basis of throttle-diaphragm elements. Some relations are derived defining the switching process of throttle-diaphragm elements. A decoding circuit of pneumatic signals is synthesized for encoding objects that have reached the working position in a conveyer line. An application example is discussed.

Keywords: logical module, throttle-diaphragm element, pneumatic signals decoder, acoustic sensors, conveyer line.
