Johnson Controls M9104-GGA-3S Series M9104 Electric Non-Spring-Return Actuator, Proportional Control, 4 Nm Torque, M3 Screw Terminals

The M9102 and M9104 Series Actuators are direct-mount, non-spring-return electric actuators that operate on AC 24 V power. These synchronous motor-driven actuators provide floating control (AGA), floating control with automatic shutoff (IGA), and proportional control with selectable 0-10 or 2-10 VDC (GGA). The -2S models are equipped with plenum cables, and the -3S models are equipped with terminal blocks. All models are compact in size and are easily installed on VAV boxes, Variable Volume and Temperature (VVT) two-position zone applications, or small- to medium-sized dampers with a round shaft up to 1/2 in. (13 mm) in diameter or a 3/8 in. (10 mm) square shaft. The M9102 Series Electric Non-Spring-Return Actuators provide a running torque of 18 lb·in (2 N·m), and the nominal travel time is 30 seconds at 60 Hz (36 seconds at 50 Hz) for 90° of rotation. The M9104 Series Electric Non-Spring-Return Actuators provide a running torque of 35 lb·in (4 N·m), and the nominal travel time is 60 seconds at 60 Hz (72 seconds at 50 Hz) for 90° of rotation.

• Short 30-Second Travel Time Available — provides a quick response for two-position zone applications
• 35 dB Nominal Audible Noise Rating — meets the audible noise requirements for open-ceiling environments
• Synchronous Drive — provides a constant rotation time that is independent of the load
• 100,000 Cycle Rating — provides years of trouble-free service
• Direct Shaft Mounting with Single-Screw Coupler — reduces installation time and provides three-point shaft gripping
