Abstract 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, each manifold block 30 is provided with connecting terminals 46a and 46b for transmitting serial signals and a connector 49 for transmitting drive control serial signals to the solenoid valves 20 and supplying drive power for switching a main valve 22. A connector 25 for transmitting and receiving power that is connected to the connector 49 when the solenoid valve 20 is mounted is provided at a position matched to the connector 49 of the manifold block. The solenoid valve 20 is provided with a slave chip 28 that extracts operation signals for solenoid valves from serial signals received through the connectors.
