Manifold solenoid valve driven by serial signals

摘要

In a manifold solenoid valve compressed air is supplied and exhausted through manifold blocks (30) on which solenoid valves (20) are mounted and which are connected, and the manifold solenoid valve is drive-controlled by serial signals transmitted to the respective solenoid valves. A fluid passage section (31) of each 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) that communicate the passages (32,33) with supply/discharge openings of the solenoid valves (20). In an electric circuit section (41) of each manifold block there is accommodated 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. Assembling the manifold solenoid valve (10) produces both communication of the passages and electrical connection.
