In a manifold solenoid valve drive-controlled by serial signals, control systems for a single valve and a double valve are achieved by simple switching of a single control system. For this purpose, in order to transmit serial signals to solenoid valves through manifold blocks 30 on which solenoid valves 20 are mounted and which are connected, a printed circuit board 45 having connecting terminals 46a and 46b for transmitting serial signals, a slave chip 47 for extracting operation signals for the solenoid valves from the serial signals, a feeder terminal 49 for supplying power to the solenoid valves 20 based on the operation signals, and a switching device 48 for switching the slave chip between a single solenoid valve mode and a double solenoid valve mode is detachably accommodated in an electric circuit section 41 of each manifold block 30. Connecting adjacent manifold blocks 30 enables common passages 32 and 33 for supply and exhaust that penetrate the manifold blocks 30 to be placed in communication and also enables the connecting terminals 46a and 46b to be interconnected.
