Schneider Electric (Barber Colman) ADDA-902-5 Potentiometer Kit

The Schneider Electric (Barber Colman) ADDA-902-5 Potentiometer Kit is a field-essential OEM replacement part engineered for precise position feedback in industrial HVAC control loops. Built for seamless integration with Barber Colman MP-2000, MP-3000, and MP-4000 series electric actuators, this 100 Ohm potentiometer provides the critical signal feedback required for accurate valve and damper positioning. With a calibrated 90-degree rotational range, it ensures that your building automation system (BAS) receives stable, linear resistance data to maintain optimal environmental setpoints and system efficiency.

For technicians servicing legacy equipment, the ADDA-902-5 is the direct equivalent to the ADDA-902-05, maintaining identical electrical characteristics and mounting footprint. This kit is designed to withstand the thermal cycling and mechanical wear common in air handling units (AHUs) and commercial boiler controls. Replacing a worn potentiometer with this genuine Schneider Electric kit eliminates "hunting" or erratic actuator behavior caused by dead spots in older resistive elements, restoring reliable proportional control and reducing overall energy consumption.

Key Benefits for Contractors

• Precise Signal Feedback: 100 Ohm resistance provides accurate positioning data for proportional control actuators.
• Full 90-Degree Travel: Matches the standard stroke of Barber Colman HVAC actuators, ensuring complete range of motion monitoring.
• OEM Compatibility: Specifically balanced for Schneider Electric and legacy Barber Colman control circuits to prevent signal noise.
• Direct Replacement: Verified identical to model ADDA-902-05 for simplified cross-referencing and inventory management.
• Rugged Electrical Design: Constructed to provide consistent feedback in demanding industrial temperature control applications.

Common Questions

Which actuators are compatible with the ADDA-902-5?
This kit is primarily designed for use with Barber Colman MP series actuators, including models MP-2130, MP-3130, and MP-4130, which require position feedback for closed-loop operation.

Can this be used for applications requiring more than 90 degrees?
No, this potentiometer is specifically calibrated for a 90-degree rotational angle. Using it beyond this range may damage the resistive element or provide inaccurate signal feedback.

Is the ADDA-902-5 the same as the ADDA-902-05?
Yes, these two part numbers refer to the same 100 Ohm potentiometer kit and are interchangeable in all technical documentation and HVAC applications.
