A manifold solenoid valve drive-controlled by serial signals permits extremely easy assembly and easy maintenance, and eliminates a possibility of erroneous wiring. For this purpose, compressed air is supplied and exhausted through manifold blocks 30 on which solenoid valves 20 are mounted and which are consecutively connected, and serial signals are transmitted to the respective solenoid valves. A fluid passage section 31 of the manifold block is provided with common passages 32 and 33 for air supply and exhaust that penetrate the respective manifold blocks 30, and channels 36 through 38 that communicate them with supply/discharge openings of the solenoid valves 20. In an electric circuit section 41 of the manifold block, a printed circuit board 45, which has connecting terminals 46a and 46b for transmitting serial signals, slave chips 47 for extracting operation signals for the solenoid valves from serial signals, and a feeder terminal 49 for supplying power to the solenoid valves 20 based on the operation signals, is accommodated. Assembling the manifold solenoid valve 10 completes communication of the passages and electrical connection.
