The digital control devices A, B, 'C systems, 1, 2.degree. 3.1 are connected by transmissions 12, 13, 141-, so that information can be transmitted between each system. Although the final analog output is optimal for the signal to be transmitted, these important signals are mutually transmitted and their values are compared in each system. The most common comparison is 2 out of 3, but since it is a digital judgment device, it can be easily processed if compared to an analog control device. The comparison results are output as digital outputs from each system, and a switching determination section 4' switches to one of the A, B, and C systems.
