Johnson Controls M9104-GGA-3S Actuator 322055-301 Optimized Airflow: Precision-spaced collecting platesThe Johnson Controls M9104 GGA 3S is a high performance proportional damper actuator engineered for precise control in VAV boxes and zone applications. Designed as a non spring return direct coupled actuator, this unit delivers a consistent 35 lb in torque (4 Nm) to ensure reliable operation of small to medium dampers. It supports versatile 0 10 VDC or 2 10 VDC control signals, and can effectively handle 4 20 mA inputs when paired with a 500 ohm
