PURPOSE: To remove control time delay of each console unit, by providing a console unit logical circuit part so as to control each console unit simultaneously in a remote controlling device in which a main operation supervisory panel and plural console units independently by a time division multiple signal.

CONSTITUTION: An output of a counter 36 latches a control output 1 of the console unit logical circuit part 16 by an OR gate 33 to send data to a driving part 28. The output of the counter 36 also sets up a one-shot flip flop 38 and generates a waveform similar to an one shot output from the console unit logical circuit part 16 to send it to a relay driving part 28 through an OR gate 34 as a relay driving signal. When the control output 2 of the console unit logical circuit part 16 is set or reset, the main operation supervisory panel sends a control signal to the console units and controls a load 30 simultaneously, and if the control is temporally suspended to stop control from the main operation supervisory panel temporally, the whole loads can be simultaneously controlled at the timing.
