Honeywell MS7503A2023 DCA 24V 27 lb-in Spring Return U-Bolt Actuator

Description

Honeywell MS7503A2023 Direct Coupled Actuator Overview

The Honeywell MS7503A2023 is a Direct Coupled Actuator (DCA) engineered for dependable damper control in commercial and residential HVAC applications. Featuring a 24V power supply, 27 lb-in torque output, and a spring return (SR) fail-safe mechanism, this actuator ensures your damper returns to a defined safe position upon loss of power — a critical feature for life-safety and energy management systems. The U-bolt mounting design simplifies installation on round damper shafts, reducing labor time and ensuring a secure, vibration-resistant connection.

Key Features

• Direct Coupled Actuator (DCA) design — no crank arm or linkage required
• 24V operating voltage for compatibility with standard HVAC control systems
• 27 lb-in torque output for reliable damper positioning
• Spring Return (SR) fail-safe operation — returns damper to safe position on power loss
• U-bolt mounting for secure, tool-friendly installation on round shafts
• Compact form factor suitable for tight mechanical spaces
• Designed for use with zone dampers, fresh air dampers, and ventilation control applications

Application

The MS7503A2023 is ideal for HVAC zoning systems, air handling units, and ventilation control where a spring return fail-safe actuator is required. The direct-coupled design eliminates the complexity of external linkages, while the U-bolt mount provides a fast, reliable connection to damper shafts in both new construction and retrofit installations.
