Honeywell M847A1031 Bracket Mounted Actuator Overview
The Honeywell M847A1031 is a dependable bracket-mounted actuator engineered for reliable two-position control in commercial and residential HVAC applications. Designed for straightforward installation and long-term performance, this spring return actuator ensures fail-safe operation — automatically returning to its default position upon loss of power. The foot-mounted design and included chain linkage make integration into damper and valve control systems fast and efficient.
Key Features
- 24 VAC operating voltage for compatibility with standard HVAC control systems
- Two-position (open/close) control for simple, reliable operation
- SPST switching for straightforward wiring and integration
- Spring return mechanism provides automatic fail-safe positioning on power loss
- Foot-mounted (bracket mount) design for secure, stable installation
- Includes chain linkage for flexible mechanical connection to dampers or valves
- Operating temperature range: 40°F to 125°F (4°C to 52°C)
Application
The M847A1031 is ideal for controlling dampers and valves in HVAC zoning systems, air handling units, and building automation applications. Its two-position SPST control logic makes it well-suited for on/off damper or valve actuation where precise modulating control is not required. The spring return function ensures the actuator defaults to a safe position during power interruptions, making it a trusted choice for critical airflow and fluid control points.
