The Festo CPV18-GE-MP-6 is an electrical valve interface that sits in the PLC expansion modules category — it bridges the control signal from a PLC or higher-level controller to pneumatic valve islands on a machine line.
Integration note
This valve interface receives the PLC's discrete output signals and converts them to pneumatic pilot commands for the valve terminal — typical in pick-and-place, packaging, or material-handling cells where centralized control drives distributed pneumatics.
