Product Description
. . . . . Johnson Controls M9216-GGA-2 Proportional Control Electric Spring Return Actuator, 140 lb∙in (16 N∙m) or 280 lb∙in (32 N∙m) in tandem electric spring return actuator for proportional control with 0 to 10 VDC feedback and auto-calibration
The M9216-GGx-2 and M9216-HGx-2 Series direct-mount, spring return electric actuators operate on 24 VAC or VDC power and are available for use with proportional controllers. These bidirectional actuators do not require a damper linkage, and are easily installed on a damper with a round shaft up to 3/4 in. (19 mm) in diameter or a square shaft up to 5/8 in. (16 mm). M9216-GGx-2 and M9216-HGx-2 actuators may be direct or remote mounted to a damper, or mounted to a valve using one of the M9000-5xx Valve Linkage Kits. A single M9216-GGx-2 or M9216-HGx-2 model delivers up to 140 lb∙in (16 N∙m) of torque. Two GGx models in tandem deliver twice the torque or 280 lb∙in (32 N∙m). The angle of rotation is mechanically adjustable from 30 to 90°. Integral auxiliary switches are available to indicate end-stop position or to perform switching functions at any angle within the selected rotation range. Position feedback is available through switches, a potentiometer, or a 0 (2) to 10 VDC signal. . Johnson Controls. Johnson Controls. M9216-GGA-2.
