Fluid power systems and components - Fluid logic circuits - Part 3: Symbols for logic sequencers and related functions
This part defines graphical symbols for sequencers and gives some rules concerning their use in circuit diagrams. Symbols given in this part shall be used for all documents and circuit diagrams concerning sequencers for data processing. Specifies two types of symbols for sequence function modules: type “input/output” (see annex A), and type “step/return” (see annex B).

About This Item
TS ISO 5784-3 addresses the graphical symbols used for logic sequencers and related functions in fluid power systems. This part standardizes how sequence steps and related functions are represented in technical documentation, helping engineers and draftspeople present the same functional idea consistently across circuit diagrams and related documents.
How sequencer symbols are organised
In general technical terms, a logic sequencer is used to describe operations that must occur in a defined order. In fluid logic circuits, that means the symbolic representation of step-by-step control logic, transitions, and associated conditions. The symbols defined in this part are intended for use in circuit diagrams and in documents connected with sequencers for data processing.
The standard specifies two symbol types for sequence function modules: an input/output type and a step/return type. This distinction helps show where a signal enters or leaves a function block, and how the sequence advances or returns between steps. In practice, such symbolic conventions make a diagram easier to interpret without changing the underlying control concept.
- Defines graphical symbols for sequencers and related functions.
- Provides some rules for using those symbols in circuit diagrams.
- Specifies two symbol types: input/output and step/return.
