PURPOSE:To obviate movable portions, useless time and cost for regular part interchange by generating two kinds of rectangular wave signals having different frequency dividing ratios so that a relay circuit controllably turns on and off the output signal according to these kinds of the output value and commands a generating circuit and each counter to start and stop. CONSTITUTION:A 4 bit decimal IC counter 22 generates two kinds of rectangular wave signal D, E having different frequency dividing ratios on the basis of the rectangular wave signal C of a generating circuit 20. Two 4 bit IC counters 23, 24 are operated by the respective rectangular wave signals D, E. And these counters generate count value set output signals F, H having different timing and thereby controllably turn on and off two relay contacts 26, 27 to generate the outputs from terminal 15, 16. Thus, movable parts, useless time and cost for regularly interchanging parts are obviated. |
