Abstract

PURPOSE: To enable one control unit to control the power supply of several input- output units by holding the power supply in ON mode by sending control signals from the control unit at short intervals of time.
CONSTITUTION: Center 1 and master equipment 100 are coupled together via modems; control unit 10 of master equipment 100 exercies ON-OFF control over the power supply of input-output units composed of device unit 20 ad terminal equipment 30 as well as data transmission control, and input-output units 20' and 30' of slave equipment 200 are brought under control over its power supply and data transmission and reception by unit 10. Power control part 21 and 21' of input- output unit 20 are provided with a circuit which supplies power for constant time on detection of a power feed command from control unit 10, and as far as the control unit repeats polling at intervals shorter than the above-mentioned constant time, the power supply is put to work.
