Abstract

PURPOSE: To prevent a controlled circuit from an important accident dependening upon anomaly occurrence, by checking data, which is output near the peak value of the power voltage waveform, near the next peak value to detect automatically presence or absence of anomaly of the output circuit accurately.
CONSTITUTION: The output of input circuit 1 which receives input signal Si is applied to shift register 2, and signal Si is converted to a series signal and is stored in memory circuit 3. Next, the series signal input to memory part 3 is operated and processed in operation and processed in operation part 4 on a basis of the program which is stored previously in the program storage area of memory part 3, and the operation result is stored temporraily in memory part under the control of control part 6, and further, the operation result is converted to parallel data by register 2 and is applied to output circuit 5 to output output signal So. Signal So is fed back as the check signal for the output circuit to register 2, and the input signal stored in memory part 3 and the check signal are compared with each other by com paring part 7; and if they do not agree with each other, an anomaly signal is output, and transmission of output signal S0 of circuit 5 is stopped by the output of comparing part 7.
