To provide a safety device in which a plurality of arithmetic units that operate in an asynchronous manner can execute processing without being aware of synchronization with other systems, and comparison processing can be executed on output data of both systems without malfunction, the safety device includes a plurality of arithmetic units each configured to output an arithmetic result of input data as arithmetic data in each control period, a first comparison unit configured to compare information indicating the control period at a timing at which each of the plurality of arithmetic units outputs the arithmetic data, a plurality of temporary storage units configured to hold the arithmetic data output by the plurality of arithmetic units, a second comparison unit configured to compare the arithmetic data held by the plurality of temporary storage units, and an output unit configured to output the arithmetic data to outside. Each of the plurality of temporary storage units outputs the arithmetic data held therein according to a comparison result from the first comparison unit, and the output unit outputs the arithmetic data output by the temporary storage units to the outside according to a comparison result from the second comparison unit.
