Honeywell MS7505A2130 Actuator

The Honeywell MS7505A2130 is a high-performance spring return direct coupled actuator designed for reliable control of air dampers and quarter-turn valves in commercial HVAC systems. This 24VAC/DC unit delivers 44 lb-in (5 Nm) torque and is engineered to provide fail-safe operation in the event of power loss. Featuring a 0/2-10 VDC modulating control signal, this actuator is a direct technical superior for MF40-7043-501 replacements. Its brushless DC submotor utilizes electronic stall protection across the entire 95-degree stroke, eliminating the need for limit switches and reducing mechanical wear. The self-centering shaft adapter ensures a secure fit on round or square shafts, while the integrated auxiliary switch allows for precise position monitoring or interlocking with auxiliary equipment. Built with a NEMA 2 plenum-rated housing, the MS7505A2130 handles ambient temperatures from -40°F to 150°F, making it a rugged choice for demanding mechanical room environments.

• Precise Modulation: Provides accurate 2-10VDC feedback and control for proportional damper positioning.
• Broad Compatibility: Efficiently replaces legacy models like the MF40-7043-501 and integrates with standard Series 70 controllers.
• Fail-Safe Reliability: Mechanical spring return ensures the damper or valve returns to its safe position during power interruptions.
• Simplified Installation: The self-centering clamping mechanism accommodates 3/8" to 5/8" round and 1/4" to 1/2" square shafts without extra linkage.
• Quiet Operation: Designed for low-noise environments with a driving rating of only 40 dB(A).

Is this actuator compatible with 4-20mA signals?
Yes, the MS7505A2130 can accept a 4-20mA control signal when utilized with a 500-ohm resistor across the input terminals.

Can the spring return direction be changed?
The fail-safe direction (clockwise or counter-clockwise) is determined by the orientation of the actuator mounting on the shaft.

What is the typical drive time for this model?
This model features a nominal 90-second drive time for modulating service, with a rapid spring return timing of less than 25 seconds.
