Honeywell M847A1031 Bracket Mounted Actuator, 24 VAC, Two Position, Spring Return

Description

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.
