Abstract

PURPOSE:To prevent power from being consumed unnecessarily by electrically operating only an interface part corresponding to a address sent out currently. CONSTITUTION:As for a digital input scan system which sends out digital inputs, applied in parallel, in series in terms of time, its interface part has an interposing switch composed of transistor Tr, and a power supply of +24V is connected to the emitter side. To the collector side, resistances R1...Rn are connected and the base side to which a voltage providing switching operation is used as address input terminal AD. Then, the address of a currently-sent signal from parallel-series converting circuit PS is inputted to each terminal AD of interface parts IF1...IFm and only an interface part in which this address agrees with that of a digital input provides signal conversion. Consequently, unnecessary power consumption can be prevented.
