Abstract:
1. A solenoid valve control device equipped with a plurality of solenoid valve blocks arranged in the form of a manifold, and a solenoid valve control unit for controlling the solenoid valve blocks, wherein: the solenoid valve blocks are connected to the solenoid valve control unit; the solenoid valve control unit includes a power supply line for performing supply of power to the solenoid valve blocks, a serial communication line for carrying out serial communications among the solenoid valve blocks, and block selection lines provided in the same number as the solenoid valve blocks; each of the solenoid valve blocks includes a plurality of solenoid valves, a solenoid valve operating circuit that operates the solenoid valves, and transfer lines; the solenoid valve operating circuit of each of the solenoid valve blocks is connected to any one of the block selection lines via one of the transfer lines within the same block; the solenoid valve control unit supplies a block selection signal for selecting a given solenoid valve block to be controlled, to the solenoid valve operating circuit of the given solenoid valve block to be controlled, via any one of the block selection lines and the transfer lines for the given solenoid valve block to be controlled, which are connected to the one of the block selection lines; and based on the block selection signal, the solenoid valve operating circuit to which the block selection signal is supplied operates the plurality of solenoid valves that are connected to that solenoid valve operating circuit.
