What a pneumatic circuit diagram is.
A pneumatic circuit diagram documents the control side of a compressed-air machine: the command devices, relay or PLC outputs, valve coils, and feedback switches. It makes clear what energizes each actuator and when.
The air paths through the directional valve, regulator, and cylinder are usually documented alongside this electrical control drawing. Together, the two views let technicians trace a motion fault from a button or sensor to a solenoid coil and the actuator it controls.

Who uses pneumatic circuit diagrams.
Cylinder and valve controls for clamps, stops, pick-and-place units, and other compact pneumatic mechanisms.
Compressor pressure-switch and contactor control circuits when diagnosing a machine that will not build or hold pressure.
PLC output and solenoid wiring before adding sensor inputs and sequence logic to a machine program.

Common questions
What is a pneumatic circuit diagram?
It shows the electrical and control connections that command pneumatic equipment, such as switches, relays, PLC outputs, valve coils, and position sensors. The air-flow circuit is often shown in a separate but related drawing.
What pneumatic components can I diagram?
You can describe solenoid valves, single- and double-acting cylinders, pressure switches, limit switches, relays, contactors, fuses, and PLC I/O.
What is the difference between a 3/2 and 5/2 valve?
A 3/2 valve supplies and exhausts one working port, which suits many single-acting cylinders. A 5/2 valve alternates pressure and exhaust between two working ports for a double-acting cylinder.
Can a PLC control a pneumatic valve?
Yes. A PLC digital output can switch a correctly rated valve coil directly or through an interface relay. Match the output type, supply voltage, coil current, and suppression method.
