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

46

a

and

46

b

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

46

a

and

46

b

to be interconnected.
