Abstract:
PURPOSE:To reduce the size of a pneumatic output type timer, by a method wherein a program stored in a memory is executed, and a pilot-type air valve is controlled in accordance with a predetermined time schedule while referring to a time generator which outputs data on elapsed time. CONSTITUTION:A central controlling circuit 4 provides a driving circuit 3 with a controlling signal necessary for energizing solenoids 21-2n in accordance with a predetermined time schedule. The time generator 5 gives elapsed time data to the controlling circuit 4, while a program memory 7 stores several kinds of controlling programs, and the contents of the memory 7 are read out to the circuit 4 by an operating switch group 6 and are excecuted.
