Abstract
A fluid control system has a first series of connected circuit boards that each actuate a respective valve unit mounted to a manifold block. A first communication module has a valve driver with a plurality of outputs for actuating the valve units connected to the first series of connected circuit boards. A serial control line extends through the first series of connected circuit boards and is connected to a second driver for actuating a second series of connected circuit boards.
Claims6
A fluid control system comprising:
- a driver device and plurality of slave devices connected to said driver device through an operating circuit for operating;
- a detection circuit connected to each slave device to detect whether said operating circuit is active;
- said respective detection circuit connected to a single serial communication line that is in communication with said driver for communicating information between said driver and said plurality of slave devices;
- a fluid valve manifold having a plurality of valve manifold blocks fastened to each other so as to form fluid pathways extending through said fluid valve manifold and a passage through each valve manifold block that aligns with each other to collectively form a continuous electrical conduit receiving a series of connected circuit boards that each actuate a valve unit mounted to each valve manifold block;
- each circuit board having a set of conductive valve lines connected to and extending between a respective set of first electrical connectors and a respective set of second mating electrical connectors;
- a conductive common line in each circuit board connected to one voltage side of a respective first electrical connector and a respective second mating electrical connector for connection to a respective conductive common line in another valve manifold block;
- and
- said single serial communication line is formed by said series of connected circuit boards with each circuit board having a line segment with a respective first electrical connector and electrically connected to a respective second mating electrical connector for connection to a respective first electrical connector in another circuit board.
