Abstract

PURPOSE: To establish the failsafe of a controller by which many kinds of control is effected, and to improve the safety, by means of monitoring the signal of the outputting terminal which repeats the state of ON and OFF by the frequency based on a program.
CONSTITUTION: One tip microcomputer 200 operates logic operation according to the program memorised in a fixed memory, and generaters the output of scan at output terminals CoWC3. A safety circuit 79 is supplying the signal to a drive circuit 70 of a relay 72 by means of receiving the input of the outputs of scan Co, C2. When the microcomputer 200 will not effect a program by some abnormalness, the outputs of scan CoWC3 are stopped, and the relay 72 becomes to OFF, and one part or the whole of the electric circuit of the control object is interrupted.
