Schneider Electric (Barber Colman) CP-8301-120 Actuator Drive

The Schneider Electric CP-8301-120 is a high-performance electronic actuator drive designed to interface electronic controller signals with Barber-Colman proportional actuators. This solid-state HVAC actuator interface operates on a 120 Vac power requirement and provides a regulated 20 Vdc, 50mA filtered power supply directly to the controller. This specific model serves as the CP-8301-620 direct replacement, ensuring seamless integration into existing BAS or pneumatic-to-electronic conversion systems. The drive accepts a wide input range of 1 to 15 Vdc, with a factory-set start point of 6 Vdc and a fixed 3 Vdc span. For specialized applications, the actuator control signal is field-adjustable from 2 to 12 Vdc across the full stroke. Built for durability in commercial mechanical rooms, the CP-8301-120 electronic drive eliminates common calibration drift issues found in older bridge-style interfaces. By maintaining precise voltage regulation, it ensures consistent damper or valve positioning, making it a critical component for commercial HVAC automation and energy management retrofits.

• Direct Replacement Logic: Engineered as the functional successor to the CP-8301-620, minimizing downtime during field upgrades.
• Regulated Power Output: Provides a stable 20 Vdc supply, eliminating the need for external transformers for many low-voltage controllers.
• Field Adjustability: Features an adjustable start point from 2 to 12 Vdc, allowing for precise sequencing and custom stroke control.
• Robust Solid-State Design: Built to withstand the electrical noise and thermal fluctuations common in industrial mechanical environments.
• Fixed Span Accuracy: The 3 Vdc fixed span ensures predictable actuator response and simplifies commissioning for technicians.

Common Questions

Is the CP-8301-120 compatible with obsolete CP-8301-620 units?
Yes, this unit is the specified direct replacement for the CP-8301-620, maintaining the same mounting footprint and terminal configuration for easy installation.

Can I adjust the start point of the actuator stroke?
While the factory setting is 6 Vdc for a 50% stroke position, the drive is fully adjustable between 2 and 12 Vdc to match the specific needs of your control sequence.

What type of power supply does this drive provide to the controller?
The drive includes a built-in regulated and filtered 20 Vdc, 50mA power supply, which is sufficient to power many Schneider Electric and Barber-Colman electronic controllers.
