M9124 Series Proportional Control Electric Non-spring Return Actuators

The M9124-GGx and M9124-HGx Series direct-mount electric actuators operate on 24 VAC or VDC power. These actuators 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). They may be direct- or remote-mounted to a damper or mounted to a valve using the M9000-518 Valve Linkage Kit. A single M9124-GGx or M9124 HGx-2 model delivers up to 210 lbin (24 Nm) of torque. Two GGx or HGx models in tandem deliver twice the torque or 420 lbin (48 Nm). The angle of rotation is mechanically adjustable from 0 to 90° in 5-degree increments. Integral auxiliary switches are available to indicate end-stop position or to perform switching functions at any angle within the selected rotation range. Jumpers on the actuator allow users to select the direction of action, range of control input, and calibration (fixed or adjustable). Position feedback is available through a 0 (2) to 10 VDC signal.
