Honeywell MS7520A2205 Actuator

The Honeywell MS7520A2205 is a high-torque, 175 lb-in spring return direct coupled actuator engineered for precise control of dampers and quarter-turn valves in commercial HVACR systems. Operating on 24V AC/DC, this S20 Series powerhouse provides ultimate flexibility by supporting both floating and modulating (0/2-10 Vdc) control signals. Built with a rugged metal housing and a brushless DC motor featuring electronic stall protection, it ensures high reliability without the need for limit switches. This model is a direct 1-to-1 professional replacement for legacy MF41-715-502 and MF41-7153-502 units, fitting seamlessly into existing Honeywell actuator layouts. The integrated self-centering shaft adapter accommodates a wide range of shaft sizes, ensuring a stable mechanical connection. With two internal SPDT auxiliary switches and a field-selectable spring return direction, this direct coupled actuator delivers the fail-safe performance and feedback necessary for complex building automation sequences.

• Universal Control Compatibility: Features a selector switch to toggle between proportional (analog) and floating control, simplifying truck stock.
• High Torque Performance: Delivers 175 lb-in of torque, capable of driving large dampers or valves with a 90-second drive time and 20-second fail-safe spring return.
• Precision Mounting: The self-centering shaft coupling eliminates mechanical play and fits 3/8" to 1.06" round or 3/8" to 11/16" square shafts.
• Integrated Feedback: Equipped with two adjustable internal auxiliary switches (SPDT) for position verification and equipment interlocking.
• Durable Construction: NEMA 2/IP54 rated aluminum housing with a manual winding crank for easy commissioning and maintenance.

Can I use this to replace an older MF41 series actuator?
Yes, the Honeywell MS7520A2205 is the recommended replacement for MF41-715-502 and MF41-7153-502. It matches the footprint and provides equivalent or superior 175 lb-in torque specifications.

What is the fail-safe position of this actuator?
The spring return direction is field-selectable. By simply flipping the actuator over, you can determine if the unit fails clockwise (CW) or counter-clockwise (CCW) upon loss of 24V power.

Does this unit require an external relay for floating control?
No, the MS7520A2205 handles floating/modulating signals directly through its internal 24V circuitry and brushless DC motor, reducing installation complexity in the field.
