Johnson Controls M9124-GGA-2 Electric Damper Actuator

The Johnson Controls M9124-GGA-2 Electric Damper Actuator provides precise proportional control for HVAC systems. This non-spring-return actuator operates at 24 Volt AC/DC and delivers reliable 90-degree rotation to modulate dampers with smooth, accurate positioning.

Engineered for reliability in commercial environments, it supports 50/60 Hz, a 24 VAC/DC supply, and a power rating of 7.5 VA. The rugged NEMA 2, IP42 enclosure and compact footprint (4.2W × 2.68D × 6H) fit tight spaces, with flexible shaft options for round (3/8–3/4 in) or square (3/8–5/8 in) damper linkages. A robust torque rating of 210 in-lb ensures quick, stable damper movement for precise airflow control.
