Manifold solenoid valve driven by serial signals

摘要

A manifold solenoid valve is drive-controlled by serial signals which are transmitted to solenoid valves 20 through interconnected manifold blocks 30 on which solenoid valves 20 are mounted. The solenoid valve 20 is made capable of receiving serial signals for single valves or double valves so as to simplify assembly and reconfiguration of the manifold solenoid valve. Each manifold block 30 is provided with female/male connecting terminals 46a and 46b for transmitting serial signals and a connector 49 for transmitting drive control serial signals to the solenoid valve 20 mounted thereon and supply drive power for switching a main valve 22 of the solenoid valve 20. A connector 25 for transmitting and receiving power is provided at a position on the solenoid valve 20 matched to the transmission and power supply connector 49 of the manifold block such that the connectors 25, 49 are connected when the solenoid valve 20 is mounted. The solenoid valve 20 is provided with a slave chip 28 that derives operation signals for the solenoid valve from serial signals received through the connectors.
