Checking for live stock

The Festo CMSX-P-S-C-U-F1-D-50-A is a double-action digital electropneumatic positioner designed to control pneumatic actuators with accuracy and repeatability. It converts electrical control signals into precise pneumatic output, allowing valves to move and hold their position reliably during operation. This unit is commonly used in process automation where stable valve positioning directly affects flow, pressure, or process consistency. Built for industrial environments, it focuses on dependable positioning rather than complex configuration or unnecessary features.

How It Benefits Users

This positioner is housed in a robust IP65-rated enclosure, making it suitable for dusty areas and locations exposed to splashing water. It is intended for installation directly on actuators, reducing the need for external tubing and simplifying setup.

Double-acting pneumatic control.
Compact, actuator-mounted design.
IP65 protection for harsh environments.
Suitable for continuous operation.
Supports long service life even in demanding plant conditions.

Control Behaviour and Signal Handling

The CMSX series uses digital control logic to ensure consistent actuator movement in response to the input signal. Once set, it maintains accurate valve positioning even when supply pressure or load conditions vary. This helps reduce process fluctuations and improves overall system stability. Because it is digitally controlled, adjustment and monitoring are more predictable compared to purely mechanical positioners. This makes it easier for maintenance teams to diagnose behaviour and keep systems running smoothly.

Typical Use of the Festo 3929313 Digital Electropneumatic Positioner IP65

This positioner is widely used in automation systems where controlled valve movement is essential. Typical uses include:

Process control valves in manufacturing lines.
Pneumatic actuators in chemical and water treatment plants.
Industrial air and fluid control systems.
Automated machinery requiring repeatable valve positioning.
