Abstract

PURPOSE:To avoid the waste of both capacity and volume for an input power source, by selecting an optional input unit circuit out of the input power source capable of supplying the current to a prescribed number of input unit circuits to supply a prescribed amount of voltage. CONSTITUTION:The input power source 10 has a capacity just enough to supply the current to a prescribed number among the input unit circuits 12a-12d. Both the input instruction and input address are applied to each input unit circuit from the controller 14 via the bus line 15. The selectors 11a-11d corresponding to the input unit circuits equivalent to the input addresses are turned on to supply the input power source 10. Accordingly, the capacity of the power source suffices for that corresponding to a part of numbers of the input unit circuits. And the value of voltage can also be varied with every input unit circuit.
