Abstract
A fluid pressure apparatus of this invention provides advanced control without imposing an excessive burden on a sequencer. When a plurality of fluid pressure apparatuses are connected to one another by manifolds, the individual fluid pressure apparatuses are provided with controller circuits each having a memory inputted with a control step, wherein each of the controller circuits activates each of control valves and a sensor based on an operating instruction issued from the sequencer to thereby execute processes such as confirmation of a controlled state, a trouble decision, etc.
Claims14
A fluid pressure apparatus for supplying and cutting off positive or negative fluid pressure to a fluid pressure controlled device connected to said apparatus, comprising:
- a housing;
- at least one directional control valve for switching between supply and cut-off of a fluid to said fluid pressure controlled device;
- detecting means including a pressure sensor disposed in an interior space inside said housing for detecting an internal pressure of the fluid flowing through said fluid pressure apparatus;
- control means disposed in said housing and having a memory means in which a plurality of different control steps are stored for locally controlling an operation of said at least one directional control valve;
- and
- display means for displaying a status of said fluid pressure apparatus thereon;
- wherein said fluid pressure apparatus comprises a plurality of blocks having respectively different functions, each block having at least one connector made of conductive elastic bodies, and wherein an electrical connection between adjacent blocks is made through the conductive elastic bodies included in said connector.
