Abstract
PURPOSE:To prevent malfunction, by providing the detection circuit discriminating the operating state of a load with the load terminal of the output conversion unit, and giving the discriminating signal of this circuit to the other output conversion unit as the interlocking signal, in the sequence controller for machine tools. CONSTITUTION:A detection circuit 5d discriinating the operating state of a load is provided at the load terminal of an output conversion unit. The interlocking adaptor terminal receiving a plurality of inputs is provided at a memory circuit 5a' using the discrimination output of the circuit 5d as the feedback signal to the control unit, and the output adaptor delivering a plurality of outputs is provided and the output terminal adaptor delivering a plurality of outputs. Further, the discrimination signal of the output conversion unit circuit 5d is given to the other conversion unit as the interlocking signal.
