On the side surface of the serial wiring block 1, there are formed a port 3 and a wiring insertion hole 4 to be connected to a port of a manifold (not shown) having waterproof and dustproof properties.
Around the opening ends of the port 3 and the wiring insertion hole 4, a second
Of the serial wiring block 1 and the manifold, and the ports and the wiring insertion holes are sealed.

The serial wiring block 1 and the solenoid valves connected to the manifold are electrically connected by wiring passing from the wiring insertion hole 4 to the wiring insertion hole of the manifold.

From the unit wiring port 5 opened on the front surface of the serial wiring block 1, wiring electrically connected to a master station unit (not shown) or another serial wiring block is connected to the wiring waterproof adapter 13. Have been taken out through.

When a local power supply is used due to a voltage drop from a local power supply wiring port 6 simultaneously opened on the front face of the serial wiring block 1, a predetermined power supply is electrically connected to the power supply waterproof adapter 14. The wiring connected to is taken out. On the other hand, when the local power supply is not used, the local power supply wiring port 6 is closed by the bushing 15.

A terminal block 16 is provided inside the serial wiring block 1. The control signal converted in parallel in the serial transmission block 2 is transmitted from each terminal of the terminal block 16 to each solenoid valve through the wiring. You.

Next, the waterproof and dustproof action of the serial wiring block 1 in this embodiment will be described.

As described above, the serial wiring block 1 of the present embodiment has the serial transmission block 2 coupled to the upper surface, the manifold (not shown) having the solenoid valve mounted on the side surface, and the serial transmission block 2 coupled to the front surface.
