Johnson Controls M9104-IGA-2S Actuator

The Johnson Controls M9104-IGA-2S is a non-spring return direct-coupled actuator designed for reliable control of dampers and valves in HVAC systems. Operating on 24VAC power, this unit provides 35 lb-in torque (4 Nm), making it an ideal choice for small to medium-sized air handlers and terminal units. It supports both floating control and two-position control configurations, featuring an integrated timeout function that de-energizes the motor after 90 seconds of inactivity to extend service life. With a 60-second travel time at 60Hz, it delivers precise positioning for HVAC damper actuators. The M9104-IGA-2S comes equipped with a 48-inch plenum cable (Cabl-48), simplifying plenum-rated installation. This motor is engineered for field-mount applications, offering a compact footprint for tight mechanical spaces. For technicians, the M9104 series actuator remains a staple for variable air volume (VAV) systems due to its straightforward brushless DC motor design and durable gear train.

• Versatile Control Logic: Supports 24VAC floating or on/off signals for seamless integration with existing building automation systems.
• Enhanced Durability: The electronic timeout feature prevents motor burnout, ensuring long-term reliability in high-cycle environments.
• Labor-Saving Install: Direct-coupled mounting with a single screw and a pre-wired plenum cable reduces field wiring time.
• Compact Profile: Small housing design allows for installation in narrow ductwork or crowded terminal boxes where space is limited.

How do I wire the M9104-IGA-2S for floating control?
The unit utilizes three wires for floating control: a common wire and two signal wires for clockwise and counterclockwise rotation. Ensure the 24VAC transformer is sized correctly for the 2.4VA power consumption.

Can this actuator be used in return air plenums?
Yes, the included 48-inch cable is plenum-rated, meeting requirements for installation within environmental air spaces.

What happens if the actuator reaches the end of its stroke?
The integrated microprocessor detects the end of travel or a stall condition and automatically cuts power to the motor after 90 seconds to prevent mechanical stress.
