PURPOSE:To stop the data delivery even if the signal is continuously outputted from the stack, by connecting pulse transformer to the final output stage and controlling the data delivery with the output signal of the transformer. CONSTITUTION:The inspection circuit 1 checks the normality of signal from the control unit A and controls the delivery of data to the unit A via the common bus from the output circuit 2 if normal. In this case, the pulse transformer PT is connected to the final stage of output as the resule of checking normality of the signal from the unit A and the output signal of the transformer PT performs data delivery control to the unit A. Thus, even if the signal is continuously outputted with the stack, the output signal of the transformer PT is zero avoid the data delivery. |
