Schneider Electric (Barber Colman) CP-9302 Actuator Drive

The Schneider Electric CP-9302 Actuator Drive provides high-precision proportional control for electric gear train actuators, converting a 4 to 20mA current input signal into reliable mechanical positioning. This unit is the direct industry replacement for the legacy Barber Colman CP-8391-910, engineered to mount directly onto proportional actuators like the MP-2000, MP-300, and MP-400 series. With a factory-preset 3% deadband and an input span of 16mAdc starting at 4mAdc, this drive ensures tight loop control and minimizes hunting in demanding HVACR environments. Because power is supplied directly from the actuator's shading coil windings, there is no need for an external power source, simplifying field wiring for contractors. The integrated jumpers allow for quick field adjustments of the input signal type and deadband, while secondary potentiometers facilitate precise calibration of the start point and span to match specific controller outputs.

• Direct Replacement: Seamlessly replaces the CP-8391-910 without requiring extensive harness modifications.
• Internal Powering: Draws necessary voltage directly from the actuator motor, reducing installation complexity and material costs.
• Advanced Override: Equipped with violet/white and violet pigtails for external override (purge) functionality, essential for smoke or freeze-stat safety sequences.
• Legacy Compatibility: Fits 24V, 120V, and 240V gear train actuators including MA-series and MP-series oil-submerged or spring-return models.
• Field Adjustable: Features onboard adjustable potentiometers to fine-tune the 16mAdc input span and 4mAdc start point for exact valve or damper modulation.

Common Questions

Can I use the CP-9302 with a voltage input instead of current?
Yes. While factory preset for 4-20mA, the CP-9302 features internal jumpers that allow technicians to reconfigure the drive for a 6 to 9 Vdc voltage input signal in the field.

Does this unit require a separate transformer?
No, the drive is powered directly from the shading coil windings of the gear train motor. However, if the actuator has an internal transformer (suffix -2 models), you must disconnect and tape the red and blue secondary leads to prevent circuit damage.

What is the purpose of the additional lead wires?
The CP-9302 includes color-coded pigtails specifically for input signal override. Connecting these to a contact closure allows for a manual or safety-triggered purge override, driving the actuator to full travel regardless of the 4-20mA signal.
