Abstract

PURPOSE:To eliminate unnecessry power consumption when the switch is left turned on by mistake, etc., by supplying electric power to a load only for a required time previously. CONSTITUTION:When an AC current is supplied between seven o'clock and eight o'clock, data [7,00] and [8,00] are set by operation part 2 and inputted to timer 3. Timer 3 is noraml one and, according to the setting, generates an output signal between seven o'clock and eight o'clock. The output signal of timer 3 is converted by output part 4 into a light signal, which is sent to receiver 7 of switch circuit 6-1 via optical fiber 5. Consequently, receiver 7 turns on switch 8 between seven o'clock and eight o'clock to supply the AC current to load 9-1. Similarly, loads 9-2 and 9-3 are supplied with the currents.
