PURPOSE:To easily control a function relay by only applying a signal showing a desired operating state, by temporarily storing a control signal by 2 latching circuits alternately, taking exclusive OR between their storage contents, and sending out a function relay driving signal. CONSTITUTION:A control signal by a generating circuit 1 is temporarily stored in latching circuits 2, 3 alternately, exclusive OR4 is taken between temporary storage contents of the latching circuits 2, 3, and a driving signal of function relays Ry0-Ry3 is sent out. Accordingly, since the function relay can be controlled by only applying a signal showing a desired operating state, its constitution and operation are simplified. |
