Johnson Controls M9124-AGA-2 Actuator

The Johnson Controls M9124-AGA-2 is a heavy-duty, non-spring return electric actuator engineered for precise positioning of dampers and valves in large-scale HVAC systems. Delivering a robust 210 lb-in torque, this direct-coupled actuator is designed for floating control or two-position signaling, operating on 24 VAC or 24 VDC power. With a standard travel time of 115 to 175 seconds, it ensures stable modulation without the risk of system hunting. The unit features 1/4 inch spade terminals for rapid electrical termination and adapts easily to round shafts up to 3/4 inch or square shafts up to 5/8 inch. This HVAC damper motor utilizes a synchronous motor technology to provide constant stall protection throughout its rotation. Field-proven in technical environments, the M9124-AGA-2 actuator is a reliable solution for air handling units and zone control systems requiring high torque output and long-term mechanical endurance.

• High Torque Output: Provides 210 lb-in (24 N·m) to drive large dampers and ball valves effectively.
• Versatile Power Compatibility: Accepts both 24 VAC and 24 VDC inputs for flexible field installation.
• Simplified Wiring: Equipped with 1/4" male spade terminals for quick, secure electrical connections.
• Easy Installation: The direct-coupled design eliminates the need for complex linkages in damper actuator applications.
• Manual Override: Features a manual gear release to allow for easy positioning during commissioning or maintenance.

Can the M9124-AGA-2 be used for proportional control?
No, this specific model is designed for floating control or on/off two-position applications. For 0-10 VDC or 4-20 mA modulation, a different series or controller interface would be required.

What is the difference between this and a spring return actuator?
This is a non-spring return actuator, meaning it stays in its last position during a power loss rather than returning to a "fail-safe" open or closed state.

What shaft sizes are compatible with this direct-coupled mount?
The universal scale allows for mounting on 3/8" to 3/4" round shafts and 1/4" to 5/8" square shafts, making it highly adaptable for various HVACR hardware replacements.
